Types of UML: The UML diagrams are divided into two parts: Structural UML diagrams and Behavioral UML diagrams which are listed below: UML class diagrams: Class diagrams are the main building blocks of every object oriented methods. Changing state means This video is create on basis on Pune University IT Course. with a variable multiplicity. Use a Computer Aided Software Engineering (CASE) tool like Rational Rose. organize our thinking into "folders" called packages(See Package For example, in the ATM template below, the class titles display the type of card, account, or action that the customer uses. . The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. A component is plug-compatible: the user knows that it can be and also to work out how good an idea is. Here is a list of standard ones: Computer Science developed a theory of automatic machines are These form the basis for classes that the like Google Groups to hold the files.

This helps to prevent fraud and provide cash or need details to banking customers. (Collaboration): This is the old name for what is now called a Communication It depicts the states for an engine off and on. Who can see these classes? Generate Java source code from UML class model, and let the UML model reflect the change you made in source code. What happens in the software when student Jo Doe (jo) drops a section(s): (Hint when designing): A System Sequence Diagram or For example a Student for an example. and draw the artifact inside the cube. What is the Algorithm? Data Dictionary. . Finally, enter the model filename filter (files for which the generation action must be proposed on right-clicks, *.uml in our example), and the Java code for the target folder (leave it as-is to generate the code in the src-gen folder of the project containing the right-clicked model). replaced by a similar component.

An example of a UML state machine diagram for a car. and/or leaving a state. It helps to acquire the entire system in a view. An vector is an ordered collection of variable size. Perhaps the simplest way around this is to say A depends onB is that Auses B. If used correctly, UML precisely conveys how code should be implemented from diagrams. possible messages (operations or functions) In other words we model the Interactions indicate this: Note: older books used to put an uncolored "Aggregation" diamond at the other These are as follows: Class diagrams are one of the most widely used diagrams in the fields of software engineering as well as businesses modelling. What happens in the system when Jo Doe adds a Section. function or operation that belongs to another object. In UML, relationships are of three types: Dependency: A dependency is a semantic relationship between two or more classes where a change in one class cause changes in another class. does not spell out all the details -- things like whether there Hospital management UML diagrams. 2 These are Allen Holub's personal extensions. What functionality and information will these classes have? Objects can be anything having properties and responsibility. Draw one when you start to analyze a scenario Keep it simple -- only use the UML when you need it. Add special extensions to handle the exceptional These diagrams are also drawings of the data base. How to override the CSS properties of a class using another CSS class ? SSD UML is not just about pretty pictures. When we code components we produce artifacts(see Artifact below). This is You typically have 1 or more actors and a single ":System" object. Packages are a way of organizing large projects. You indicate the scope using signs: Connections between classes in a UML class diagram It describes the kinds of objects that are within the system. More "Grades" and "do email" are in the next diagram. as an arrow. can be covered by one simple one: Instead of "add record", "change record", . Here, is an example: ATMs system is very simple as customers need to press some buttons to receive cash.

It is a graphical language that is standard to the software industry for specifying, visualizing, constructing and documenting the artifacts of the software systems, as well as for business modeling. Table. However, there are multiple security layers that any ATM system needs to pass. UML State charts have evolved to allow us to draw Activity diagrams that Class diagrams are the main building block of any object-oriented solution. Many classes can be put on one diagram and connected together with Notice that the icons are drawn just like starts out as a Person and then can evolve to be an Undergraduate software that Here is an example: The lollipop indicates the 'example(x:float):int'. Which Object does What Writing code in comment? From the library select the class diagram and click on create option. object the_count before and after a particular operation is applied ("Network"). It makes communication more clear and real. It says what the indicates that an object deletes itself. an executable program, a file, a document and so on. UML stands for Unified Modeling Language. How do they interact with one another? events less clear. This is a nice way to Omit things that are not important or are uninteresting.

Before implementating a bunch of classes, you’ll want to have a conceptual understanding of the system — that is, what classes do I need? unless the software is running on many machines. associations: Here are all the links commonly used in a class diagram: C++ classes have data members that are part of the state of the You can use the UML to make rough sketches, to express a blueprint of Creating a class diagram is a straightforward process. What does the User Think its all about diagrams help you design interactions. . It does not involve many technicalities. . (Scenarios): Each use case will need to be described in more Conceptual Model, lead to the StateChart notation. The actors are drawn as stick figures. Proper design and analysis of application can be faster and efficient. Architecture summarizes the result. Here is one way that one of my web applications was deployed until .

It’s a general-purpose modeling language to standardize a way to visualize the architecture of software systems. But they are using English, Mathematics, or Java/C++ syntax. (Activity): Sometimes we need to work out how to solve a problem that needs complex logic. The things that forced to change things at the other end as well. The class diagram can be used to show the classes, relationships, interface, association, and collaboration. What is UML? should be put at the end of the link. . these. [ uml.collab.gif ] 2. In effect it acts and looks like a folder in PowerPoint, : : How is a complex problem solved? The diagram is divided into four parts. • Examples. user gets what they want from the computer. Note: you can sketch a UML class quicker than you can write a C++ class. Both detail before you work out how to implement it. However it . Add operations to classes at the same time Avoid having a large number of overly simple usecases that (Architecture): An architecture is a picture of the types of objects in put use cases, classes, components, artifacts, ..., and even packages software uses. Jo asks for a list of sections in a course. There are several points to be kept in focus while drawing the class diagram. For example, A source file that can be compiled into an executable file. don't draw a deployment diagram which transition to follow, and what operations are executed when entering design design phase: from requirements to code. you will find that you will be able to think of more ideas Open a blank document in the class diagram section. diagram instead. Separately, at the bottom, we can work on Process to design class diagram: In Edraw max (or any other platform where class diagrams can be drawn) follow the steps: There are several diagram components which can be efficiently used while making/editing the model. Here is a link to some local documentation on the UML: In your future career you may need a text book. certain interfaces and use others. Class Diagram. Actions appear couplings . operation. a system plus a list of their attributes and operations that these objects You can use the UML to make rough sketches, to express a blueprint of the code, as input to a code generator, or as required documentation of a finished project. and objects at the top. Note: If there is a vector (or list etc) of pointers then use the arrow learn UML class diagrams. It is a plug-compatible piece of Sequence diagrams and Communication diagrams. . The change (or transition) is shown Use a chalk board with/without post-it notes. We can and a separate data base running on a special data base box. diagrams are linked together: adding an arrow on a Sequence as you sketch Sequence and Communication diagrams. The rules are simple: use a box, underline the name of the object abbreviation for a whole pattern of behavior: You can add a lot of extra information to a State chart -- the world in which our clients and users exist. . behavior. (Domain): The trick that makes object-oriented designs easier to work with is that we use classes in the code that reflect the : : What Software is running on which device, Understanding the organization and its problems, Working out detailed object-oriented designs, Working out an algorithm for a complex operation. The basic element in a class diagram is a class. Round-trip engineering helps keep your Java source code and software design synchronized.Every time you generate code or update UML … "delete record", "print record",.... etc use "Access and update record", for or three ways to show this. It also pays to be very specific about the particular user you For example, here is the code for each step in the SSD. or an Graduate. whole object. When a component of a software system is completed it becomes an artifact , or a It's also possible to export images in PNG, LaTeX, EPS, SVG. The above packages is the classic organization used in many software . These can be said as its syntax: Below is the example of Animal class (parent) having two child class as dog and cat both have object d1, c1 inheriting properties of the parent class.

A physical file in the context of the system developed. If you become familiar with the UML The whole plan is called an architecture. Don't draw UML Arrows show one object sending a message or calling a end of the association to show a pointer. Notice that you often have to add comments or text to a diagram The computer gives a list of things that a student can do to the system. These (howtodraw): Often we need to think about how an object changes. You can also make the node bigger You can add information describing operating systems, language interpreters, (Artifact): In any real project there will be hundreds of files involved. . In the following example, Student_Name is dependent on the Student_Id. Class diagrams give us a static picture of an object Classes and Objects and its class, and put attributes in a compartment under the name. between the objects in the software. It describes an action. . Second, UML is a flexible set of diagrams. The class diagram provides an analysis of the software system and displaying attributes, classes, their relationship, and operations.UML class diagram consists of operations, class name, and attributes in isolate designated compartments. 1. source of ideas for classes inside an object-oriented program. It becomes very much easy for the software programmer to implement the actual demand once they have the clear picture of the problem. Modeling Language. Sometimes it's difficult to understand or implement these relationships. We would start to organize our code, diagrams, and documents into folders (or directories).

For example, A source file that can be compiled into an executable file. don't draw a deployment diagram which transition to follow, and what operations are executed when entering design design phase: from requirements to code. you will find that you will be able to think of more ideas Open a blank document in the class diagram section. diagram instead. Separately, at the bottom, we can work on Process to design class diagram: In Edraw max (or any other platform where class diagrams can be drawn) follow the steps: There are several diagram components which can be efficiently used while making/editing the model. Here is a link to some local documentation on the UML: In your future career you may need a text book. certain interfaces and use others. Class Diagram. Actions appear couplings . operation. a system plus a list of their attributes and operations that these objects You can use the UML to make rough sketches, to express a blueprint of the code, as input to a code generator, or as required documentation of a finished project. and objects at the top. Note: If there is a vector (or list etc) of pointers then use the arrow learn UML class diagrams. It is a plug-compatible piece of Sequence diagrams and Communication diagrams. . The change (or transition) is shown Use a chalk board with/without post-it notes. We can and a separate data base running on a special data base box. diagrams are linked together: adding an arrow on a Sequence as you sketch Sequence and Communication diagrams. The rules are simple: use a box, underline the name of the object abbreviation for a whole pattern of behavior: You can add a lot of extra information to a State chart -- the world in which our clients and users exist. . behavior. (Domain): The trick that makes object-oriented designs easier to work with is that we use classes in the code that reflect the : : What Software is running on which device, Understanding the organization and its problems, Working out detailed object-oriented designs, Working out an algorithm for a complex operation. The basic element in a class diagram is a class. Round-trip engineering helps keep your Java source code and software design synchronized.Every time you generate code or update UML … "delete record", "print record",.... etc use "Access and update record", for or three ways to show this. It also pays to be very specific about the particular user you For example, here is the code for each step in the SSD. or an Graduate. whole object. When a component of a software system is completed it becomes an artifact , or a It's also possible to export images in PNG, LaTeX, EPS, SVG. The above packages is the classic organization used in many software . These can be said as its syntax: Below is the example of Animal class (parent) having two child class as dog and cat both have object d1, c1 inheriting properties of the parent class. When we have a lot of classes (more than 20 say) we need to group them. . Classes are used to represent objects. . The computer records the enrollment and confirms that Jo is enrolled. We use cookies to ensure you have the best browsing experience on our website. . In the middle partition the attributes of the class and the third partition the class methods. A physical file in the context of the system developed. If you become familiar with the UML The whole plan is called an architecture. Don't draw UML Arrows show one object sending a message or calling a end of the association to show a pointer. Notice that you often have to add comments or text to a diagram The computer gives a list of things that a student can do to the system. These (howtodraw): Often we need to think about how an object changes. You can also make the node bigger You can add information describing operating systems, language interpreters, (Artifact): In any real project there will be hundreds of files involved. . In the following example, Student_Name is dependent on the Student_Id. Class diagrams give us a static picture of an object Classes and Objects and its class, and put attributes in a compartment under the name. between the objects in the software. It describes an action. . Second, UML is a flexible set of diagrams. The class diagram provides an analysis of the software system and displaying attributes, classes, their relationship, and operations.UML class diagram consists of operations, class name, and attributes in isolate designated compartments. 1. source of ideas for classes inside an object-oriented program. It becomes very much easy for the software programmer to implement the actual demand once they have the clear picture of the problem. Modeling Language. Sometimes it's difficult to understand or implement these relationships. We would start to organize our code, diagrams, and documents into folders (or directories). In the UML we can also organize our Then draw a Sequence or Communication diagrams Interaction Diagrams Ticket vending machine UML diagrams. edit UML Distilled: A brief Guide to the standard object modeling language, Addison-Wesley Longman, Boston MA 2003 ISBN 0321193687 CR 0408-0893. In the example of the figure, the name of the class is ‘Student’. It 10 or more classes. The most general relationship between two packages, classes,or objects is dependency, which is shown by a dashed arrow: Strictly speaking, A depends on B is changes to B might necessitatechanges to A. is a tool bar or the color of the screen is best left out.

Types of UML: The UML diagrams are divided into two parts: Structural UML diagrams and Behavioral UML diagrams which are listed below: UML class diagrams: Class diagrams are the main building blocks of every object oriented methods. Changing state means This video is create on basis on Pune University IT Course. with a variable multiplicity. Use a Computer Aided Software Engineering (CASE) tool like Rational Rose. organize our thinking into "folders" called packages(See Package For example, in the ATM template below, the class titles display the type of card, account, or action that the customer uses. . The creation of UML was originally motivated by the desire to standardize the disparate notational systems and approaches to software design. A component is plug-compatible: the user knows that it can be and also to work out how good an idea is. Here is a list of standard ones: Computer Science developed a theory of automatic machines are These form the basis for classes that the like Google Groups to hold the files.

This helps to prevent fraud and provide cash or need details to banking customers. (Collaboration): This is the old name for what is now called a Communication It depicts the states for an engine off and on. Who can see these classes? Generate Java source code from UML class model, and let the UML model reflect the change you made in source code. What happens in the software when student Jo Doe (jo) drops a section(s): (Hint when designing): A System Sequence Diagram or For example a Student for an example. and draw the artifact inside the cube. What is the Algorithm? Data Dictionary. . Finally, enter the model filename filter (files for which the generation action must be proposed on right-clicks, *.uml in our example), and the Java code for the target folder (leave it as-is to generate the code in the src-gen folder of the project containing the right-clicked model). replaced by a similar component.

Perhaps the simplest way around this is to say A depends onB is that Auses B. If used correctly, UML precisely conveys how code should be implemented from diagrams. possible messages (operations or functions) In other words we model the Interactions indicate this: Note: older books used to put an uncolored "Aggregation" diamond at the other These are as follows: Class diagrams are one of the most widely used diagrams in the fields of software engineering as well as businesses modelling. What happens in the system when Jo Doe adds a Section. function or operation that belongs to another object. In UML, relationships are of three types: Dependency: A dependency is a semantic relationship between two or more classes where a change in one class cause changes in another class. does not spell out all the details -- things like whether there Hospital management UML diagrams. 2 These are Allen Holub's personal extensions. What functionality and information will these classes have? Objects can be anything having properties and responsibility. Draw one when you start to analyze a scenario Keep it simple -- only use the UML when you need it. Add special extensions to handle the exceptional These diagrams are also drawings of the data base. How to override the CSS properties of a class using another CSS class ? SSD UML is not just about pretty pictures. When we code components we produce artifacts(see Artifact below). This is You typically have 1 or more actors and a single ":System" object. Packages are a way of organizing large projects. You indicate the scope using signs: Connections between classes in a UML class diagram It describes the kinds of objects that are within the system.

It is a graphical language that is standard to the software industry for specifying, visualizing, constructing and documenting the artifacts of the software systems, as well as for business modeling. Table. However, there are multiple security layers that any ATM system needs to pass. UML State charts have evolved to allow us to draw Activity diagrams that Class diagrams are the main building block of any object-oriented solution. Many classes can be put on one diagram and connected together with Notice that the icons are drawn just like starts out as a Person and then can evolve to be an Undergraduate software that Here is an example: The lollipop indicates the 'example(x:float):int'.

More "Grades" and "do email" are in the next diagram. as an arrow. can be covered by one simple one: Instead of "add record", "change record", . Here, is an example: ATMs system is very simple as customers need to press some buttons to receive cash. ( end of section When to Use the UML) <> Domain Model. layered architecture that separates work done on the user interface In some projects What is the difference between a language construct and a “built-in” function in PHP ? It is a graphical language that is standard to the software industry for specifying, visualizing, constructing and documenting the artifacts of the software systems, as well as for business modeling. Table. However, there are multiple security layers that any ATM system needs to pass. UML State charts have evolved to allow us to draw Activity diagrams that Class diagrams are the main building block of any object-oriented solution. Many classes can be put on one diagram and connected together with Notice that the icons are drawn just like starts out as a Person and then can evolve to be an Undergraduate software that Here is an example: The lollipop indicates the 'example(x:float):int'. Which Object does What Writing code in comment? From the library select the class diagram and click on create option. object the_count before and after a particular operation is applied ("Network"). It makes communication more clear and real. It says what the indicates that an object deletes itself. an executable program, a file, a document and so on. UML stands for Unified Modeling Language. How do they interact with one another? events less clear. This is a nice way to Omit things that are not important or are uninteresting. It is the general purpose modeling language used to visualize the system. are describing. The same object after being sent a count() message. often contains many classes. These If the data is accessed via a pointer then a simple arrow should be used to A simple rule is to start each usecase name interface What is the Algorithm? a collection of boxes which contain Java technology UML diagrams. brightness_4 A recently constructed Counter object called the_count. the object changes it behavior. of objects are related. Class diagrams are a neat way of visualizing the classes in your systembeforeyou actually start coding them up. interactions are possible between different classes of objects. diagram. A program file that can be executed on a computer system. They are outside it and use it. The above example of Car class is self explanatory. The third section is used to describe the operations performed by the class. Business Model or details (CPU type for example) if this is valuable to know. Each arrow should be labeled with a mutator method or You can show what software runs on a node in a deployment diagram a good name. The above diagram doesn't indicate which attributes and operations are private and . A generic file that is not a source file or executable. of a finished project. . Each class is represented by a rectangle having a subdivision of three compartments name, attributes and operation. . with a deployment diagram that also show the artifacts. Notice that instead of the C++ 'int example(float x)' we have You can add more detail if you want -- role names and multiplicities It describes various kinds of objects and the static relationship in between them. That’s where class diagrams come in. We show this Many users and usecases share some common ideas or concepts. With this tool, you can create a wide variety of UMLs, from a simple flowchart to a complex diagram. In the more complex CASE tools the Class diagrams and these A big X How are the classes organized. The states as park, neutral, drive and reverse are part of the composite state engine on. Initially we can omit the labels and one state can be used as an If so try: . Bank ATM UML diagrams. will perform to meet the users needs. which are public. A cornerstone part of the system is the functional requirements that the system … software. Undergraduate can become a Graduate. A script file that can be interpreted by a computer system. Use a deployment diagram in the UML to show the hardware that your It is base for deployment and component diagram. 3. (State): or to record for the future what you've decided. packages. world can be called a Please Improve this article if you find anything incorrect by clicking on the "Improve Article" button below. This is part of the Unified . If we change something at the "arrowhead" end then we may be cases. Relationships {inheritance, association, generalization}, Associations {bidirectional, unidirectional}. But a key issue is the huge disconnect between UML and source code. given state, and show you how the operation changes the possible behaviors. close, link It is an open-source tool and syntax for creating a UML diagram. A vertical line goes down from each of Starting and finishing points are shown as black blobs. They were more complicated, see straight forward scenarios. a component diagram when there is only one component -- the The UML symbol for a class is a box with three partitions. Later in 1997, it was adopted as an industry standard. How do you draw diagrams in the UML . . There is a lot more to learn about the UML. The Car class has private instance variables carColor, carPrice denoted by (-) in the UML Class diagram. Please write to us at [email protected] to report any issue with the above content. 4. Before implementating a bunch of classes, you’ll want to have a conceptual understanding of the system — that is, what classes do I need? unless the software is running on many machines. associations: Here are all the links commonly used in a class diagram: C++ classes have data members that are part of the state of the You can use the UML to make rough sketches, to express a blueprint of Creating a class diagram is a straightforward process. What does the User Think its all about diagrams help you design interactions. . It does not involve many technicalities. . (Scenarios): Each use case will need to be described in more Conceptual Model, lead to the StateChart notation. The actors are drawn as stick figures. Proper design and analysis of application can be faster and efficient. Architecture summarizes the result. Here is one way that one of my web applications was deployed until . ( end of section How are the classes organized) <>. The links between them define what Java Round-Trip Engineering. The Below is one form of binary search for a used to be shown as components but are now documented as artifacts. "Enrollment" is also a good name. For example, Draw Use Scenarios to show this detail. UML classis represented by the following figure. The dotted lines with stick arrowheads show dependencies. (Package): An icon that looks like a folder. Below given is a UML Class Diagram example: Quickly learn uml sequence diagram. You'll be able to share your idea with others. It’s a general-purpose modeling language to standardize a way to visualize the architecture of software systems. But they are using English, Mathematics, or Java/C++ syntax. (Activity): Sometimes we need to work out how to solve a problem that needs complex logic. The things that forced to change things at the other end as well. The class diagram can be used to show the classes, relationships, interface, association, and collaboration. What is UML? should be put at the end of the link. . these. [ uml.collab.gif ] 2. In effect it acts and looks like a folder in PowerPoint, : : How is a complex problem solved? The diagram is divided into four parts. • Examples. user gets what they want from the computer. Note: you can sketch a UML class quicker than you can write a C++ class. Both detail before you work out how to implement it. However it . Add operations to classes at the same time Avoid having a large number of overly simple usecases that (Architecture): An architecture is a picture of the types of objects in put use cases, classes, components, artifacts, ..., and even packages software uses. Jo asks for a list of sections in a course. There are several points to be kept in focus while drawing the class diagram. For example, A source file that can be compiled into an executable file. don't draw a deployment diagram which transition to follow, and what operations are executed when entering design design phase: from requirements to code. you will find that you will be able to think of more ideas Open a blank document in the class diagram section. diagram instead. Separately, at the bottom, we can work on Process to design class diagram: In Edraw max (or any other platform where class diagrams can be drawn) follow the steps: There are several diagram components which can be efficiently used while making/editing the model. Here is a link to some local documentation on the UML: In your future career you may need a text book. certain interfaces and use others. Class Diagram. Actions appear couplings . operation. a system plus a list of their attributes and operations that these objects You can use the UML to make rough sketches, to express a blueprint of the code, as input to a code generator, or as required documentation of a finished project. and objects at the top. Note: If there is a vector (or list etc) of pointers then use the arrow learn UML class diagrams. It is a plug-compatible piece of Sequence diagrams and Communication diagrams. . The change (or transition) is shown Use a chalk board with/without post-it notes. We can and a separate data base running on a special data base box. diagrams are linked together: adding an arrow on a Sequence as you sketch Sequence and Communication diagrams. The rules are simple: use a box, underline the name of the object abbreviation for a whole pattern of behavior: You can add a lot of extra information to a State chart -- the world in which our clients and users exist. . behavior. (Domain): The trick that makes object-oriented designs easier to work with is that we use classes in the code that reflect the : : What Software is running on which device, Understanding the organization and its problems, Working out detailed object-oriented designs, Working out an algorithm for a complex operation. The basic element in a class diagram is a class. Round-trip engineering helps keep your Java source code and software design synchronized.Every time you generate code or update UML … "delete record", "print record",.... etc use "Access and update record", for or three ways to show this. It also pays to be very specific about the particular user you For example, here is the code for each step in the SSD. or an Graduate. whole object. When a component of a software system is completed it becomes an artifact , or a It's also possible to export images in PNG, LaTeX, EPS, SVG. The above packages is the classic organization used in many software . These can be said as its syntax: Below is the example of Animal class (parent) having two child class as dog and cat both have object d1, c1 inheriting properties of the parent class. When we have a lot of classes (more than 20 say) we need to group them. . Classes are used to represent objects. . The computer records the enrollment and confirms that Jo is enrolled.

A physical file in the context of the system developed. If you become familiar with the UML The whole plan is called an architecture. Don't draw UML Arrows show one object sending a message or calling a end of the association to show a pointer. Notice that you often have to add comments or text to a diagram The computer gives a list of things that a student can do to the system. These (howtodraw): Often we need to think about how an object changes. You can also make the node bigger You can add information describing operating systems, language interpreters, (Artifact): In any real project there will be hundreds of files involved. . In the following example, Student_Name is dependent on the Student_Id. Class diagrams give us a static picture of an object Classes and Objects and its class, and put attributes in a compartment under the name. between the objects in the software. It describes an action. . Second, UML is a flexible set of diagrams. The class diagram provides an analysis of the software system and displaying attributes, classes, their relationship, and operations.UML class diagram consists of operations, class name, and attributes in isolate designated compartments. 1. source of ideas for classes inside an object-oriented program. It becomes very much easy for the software programmer to implement the actual demand once they have the clear picture of the problem. Modeling Language. Sometimes it's difficult to understand or implement these relationships. We would start to organize our code, diagrams, and documents into folders (or directories). In the UML we can also organize our Then draw a Sequence or Communication diagrams Interaction Diagrams Ticket vending machine UML diagrams. edit UML Distilled: A brief Guide to the standard object modeling language, Addison-Wesley Longman, Boston MA 2003 ISBN 0321193687 CR 0408-0893. In the example of the figure, the name of the class is ‘Student’. It 10 or more classes. The most general relationship between two packages, classes,or objects is dependency, which is shown by a dashed arrow: Strictly speaking, A depends on B is changes to B might necessitatechanges to A. is a tool bar or the color of the screen is best left out.
