The purpose of the class diagram can be summarized as −Īnalysis and design of the static view of an application.īase for component and deployment diagrams.Ĭlass diagrams are the most popular UML diagrams used for construction of softwareĪpplications. It is the most popular UML diagram in the coder community. UML diagrams like activity diagram, sequence diagram can only give the sequence flow of the application, however class diagram is a bit different. Class diagrams are the only diagrams which can be directly mapped with object-oriented languages and thus widely used at the time of construction. The purpose of class diagram is to model the static view of an application. It is also known as a structural diagram.
The class diagrams are widely used in the modeling of objectoriented systems because they are the only UML diagrams, which can be mapped directly with object-oriented languages.Ĭlass diagram shows a collection of classes, interfaces, associations, collaborations, andĬonstraints.

Activity Diagram Examplesįollowing are activity diagram templates that are instantly editable. Now it’s time to assign them a swimlane and group each action they are responsible for under them. You have already figured out who is responsible for each action. And do you have to complete some actions before you can proceed to others? Step 4: Add swimlanes Mark down the conditions that have to be met in order to carry out certain processes, which actions occur at the same time and whether you need to add any branches in the diagram. Step 3: Find a flow among the activitiesįigure out in which order the actions are processed. If you already have figured out who the actors are, then it’s easier to discern each action they are responsible for. Step 2: Identify the actors who are involved Here you need to identify the various activities and actions your business process or system is made up of. Step 1: Figure out the action steps from the use case

Following are the commonly used activity diagram symbols with explanations. UML has specified a set of symbols and rules for drawing activity diagrams. They can be used to examine business processes in order to identify its flow and requirements. UML activity diagrams can also be used to depict a flow of events in a business process. It is a behavioral diagram that illustrates the flow of activities through a system. Scroll down to find Ī UML activity diagram helps to visualize a certain use case at a more detailed level.
In this activity diagram tutorial, we hope to cover everything you need to know about activity diagrams to learn and master it. And because they are a lot similar to flowcharts, they are generally more popular than other UML diagram types. Activity diagrams can be used in all stages of software development and for various purposes.
