Shlaer-Mellor OOA Diagram Software

Edraw contains special shapes and settings for creating Shlaer-Mellor OOA diagrams.

In Edraw Professional, the Shlaer-Mellor OOA templates and shapes are in the Software folder.

Shlaer-Mellor OOA

Edraw is a very easy-to-use and intuitive database design tool and Shlaer-Mellor OOA diagramming tool which can save you hundreds hours of work.

Edraw is not only an excellent tool for database & ER Diagram, but also the one that allows you to design flowchart, program structures, create detailed HTML or PDF reports.

Who Can Use Them and How

  • Software developers: Diagram Shlaer-Mellor OOA in object-oriented programming.
  • Software designers: Show the relationship between objects and the interfaces they reference.

Shlaer-Mellor OOA Symbols

Given the presence of four Edraw object-oriented diagram templates, and the fact that many of the diagramming methods contribute to UML emerging as a standard, it is instructive to review each template and note its features.

Sally Shlaer and Stephen Mellor

The Shlaer/Mellor method is considered an older technique that should be used in existing projects that have not migrated to UML. The major components of this model include:

  • Domain chart - used to partition the system into domains and subsystems.
  • Information Model - used to build a static analysis model of a system. This shows objects, relationships, and inheritance structures, and define class attributes and methods. Designate primary keys and formalize relationships.
  • State model - used to analyze the object's behavior over time.
  • Process Diagram, or Action Data Flow Diagram, for an action shown in the State Model.
  • Object Communication Model (OCM) - summarizes the asynchronous event communication between state models in the system.
  • Object Access Model (OAM) - summarizes the synchronous communication between state models and object instance data.
