Most PowerDesigner models contain diagrams, in which your model objects are represented by symbols. You can add a dependency matrix to any model to show relationships between objects.
Diagrams
A diagram is a graphical view of a model or a package. All models and packages have at least one diagram.
Dependency Matrices
You can create dependency matrices to review and create links between any kind of objects. You can create an individual matrix from the Browser or define a matrix in a resource file for reuse.
Symbols
PowerDesigner provides multiple tools and techniques for manipulating object symbols in your model diagrams.
