View the Cube Schema
The Data Source View pane of the Cube Structure tab in Cube Designer displays the cube schema. The schema is the set of tables from which the measures and dimensions for a cube are derived. Every cube schema consists of one or more fact tables and one or more dimension tables on which the measures and dimensions in the cube are based.
The Data Source View pane of the Cube Structure tab displays a diagram of the data source view on which the cube is based. This diagram is a subset of the main diagram of the data source view. You can hide and show tables in the Data Source View pane and view any existing diagrams. However, you cannot make changes (such as adding new relationships or named queries) to the underlying schema. To make changes to the schema, use Data Source View Designer.
When you create a cube, the diagram displayed in the Data Source View pane of the Cube Structure tab is initially the same as the Show All Tables diagram in the data source view for the project or database. You can replace this diagram with any existing diagram in the data source view and make adjustments in the Data Source View pane.
While you work with the diagram in Cube Designer, commands that act on the tab or on any selected object in the tab are available on the Data Source View menu. You can also right-click the background of the diagram or any object in the diagram to use commands that act on the diagram or selected object. You can:
Switch between diagram and tree formats.
Arrange, find, show, and hide tables.
Show friendly names.
Change the magnification.
Additionally, you can perform the actions listed in the following table:
Use a diagram from the data source view of the cube
Show only the tables that are used in the cube
Edit the data source view schema
