Edraw contains special shapes and setting for creating Jacobson's Use Case Diagrams. Use case diagrams illustrate how the outside world interacts with elements of the application system.

In Edraw Professional, the Jacobson's Use Case template and shapes are in the Software folder.

Who can use them and how

• Software developers: Represent software applications using the Unified Modeling Language (UML) notation.

• Software developers: Illustrate and interpret software application relationships, actions, and connections.

• Program managers: Show high-level static software structures in presentations and specification documentation.

Jacobson's Use Case Symbols

Jacobson's Use Case Symbols include the Jacobson's analysis model and Jacobson's design model. Jacobson's analysis model defines three types of objects in a system: interface objects, entity objects, and control objects. Jacobson's design model shows how the system behaves. There are two types of diagrams under this model: interaction diagrams and state transition diagrams. Interaction diagrams are similar to UML's sequence diagrams. State transition diagrams are like UML statechart diagrams, but Jacobson also employs a number of unique symbols listed below.

Jacobson's Object-Oriented Software Engineering

Ivar Jacobson's Object-Oriented Software Engineering (OOSE) is one of the precursors to the more modern Unified Modeling Language (UML). OOSE includes a requirements, an analysis, a design, an implementation, and a testing model. The relationship between the central use case diagram and the various models is illustrated below.
