INTERACTION DIAGRAM SOFTWARE

These diagrams are used by software developers and business professionals to understand requirements for a new system or to document an existing process. Sequence diagram is used to visualize the sequence of calls in a system to perform specific functionality. Sequence diagram shows interactions between objects over a specific period of time. UML Sequence Diagram:Ī sequence diagram is a type of interaction diagram because it describes how-and in what order-a group of objects works together. UML diagram which we have created and requirement and design phase are required in this phase as we need to test complete system. Whatever we have created in design phase we can use in development phase. Based on requirement only create UML diagrams. Again it is not necessary to create each diagram for smaller project. Other than use case and activity diagram, we can create in this phase. If use cases are being complicated then we can create activity diagram. In this phase use case diagram is required. Based on project requirement it is created.

UML Behavioral Diagrams depict the elements of a system that are dependent on time and dynamic concepts of the system and it also manage how they relate to each otherĪll UML diagram are not required in each phase of project. Below are types of structural UML diagram These static elements forms the main structure and those are stable. UML Structural diagrams depict the static elements of a system that are independent of time. UML diagram are divided in below two categories based on type of information need to show. UML diagram should be created once requirement phase is completed or some time it is also created in requirement phase.
