Working with the Cross Schema Diagram

The Cross Schema Diagram tab displays every schema currently included in the model. You can:

•

View the resources (schemas and views) and the tables in each schema.

•

View all relationships, both within schemas and between schemas.

•

Create relationships and edit existing relationships.

To work with the Cross Schema Diagram

1.

Open a model.

2.

Select the Cross Schema Diagram tab at the bottom of the window.

Discovery displays a diagram that shows all schemas that are currently in the model. In this example, the two schemas are shown as blue boxes.

3.

Optionally: select a schema, right-click to display the pop-up menu, and choose one of the options.

Note: The diamond indicates the current selection.

•

Show Tables with Cross Schema Relationships—Displays only relationships between the selected schema and other schemas in the model.

•

Show Tables with Relationships—Displays all relationships both within the selected schema and between it and other schemas in the model.

Double-clicking any table shows its key columns. Double-clicking again displays all columns.

You can also do most of the same things in the Cross Schema Diagram that you can do in the model Diagram tab including:

—

Rearrange tables and relationships in the schema (see Rearranging the Tables, Views, and Relationships).

—

Create or edit a relationship (see Defining Relationships or Editing Relationships).

—

Get relationship details (see Viewing Relationship Details).

—

Print the current display (see Printing the Model Diagram).
