Chapter 3 Building Physical Diagrams

Using extended dependencies for views

Extended dependencies are links between physical diagram objects. These links help to make object relationships clearer between model objects but are not interpreted and checked by PowerDesigner as they are meant to be used for documentation purposes only.

You can complement these links by applying stereotypes.

You can type stereotypes directly in the Stereotype column of the object property sheet or select a value from the dropdown listbox if you have previously defined stereotypes in an embedded or imported extended model definition (.XEM).

You can use extended dependencies between a view and tables links in the model.

Example

A view identified as Book Sales can have two extended dependencies indicating that the view depends on the Title and Sale tables. The diagram displays their extended dependencies and stereotypes.
