Data overview diagrams

Overview diagrams are diagrams that automatically include all or selected data objects. Overview diagrams that use Information Engineering (IE) or Unified Modeling Language (UML) notation can find and draw implicit foreign key relationships.

You can use overview diagrams to better understand the interaction between data objects.

Overview diagrams are accessible from the Data Source Explorer or from a physical or logical model in the Data Project Explorer.

When you create an overview diagram, the preferences that you specify in the Preferences window are used to determine the appearance of the diagram. You specify the compartment display options after you create the overview diagram. All of the compartments of data objects are collapsed until you expand them in the diagram.

You can create overview diagrams from the following levels in logical and physical data models:
Database or package level
Use the Diagrams folder to create an overview diagram that includes data objects from multiple schemas or packages.
Schema or subpackage level
Use the Diagrams folder to create overview diagrams that include objects from that schema or package.

For logical data models, you can also create overview diagrams from multiple subpackages.

You can also add data objects to a new overview diagram by right-clicking the data objects in the Data Project Explorer and selecting Add to Overview Diagram.
