Chapter 4 Building Conceptual Data Models

Arranging a list of entity attributes

Each entity has its own list of entity attributes.

In a list of entity attributes, you can arrange items in any order. When you generate a PDM, the order of entity attributes becomes the order of column generation.

To arrange a list of entity attributes:

1. Double-click an entity symbol to display the entity property sheet.
2. Click the Attributes tab to display the corresponding page.
   
   It lists the data items attached to the entity.
3. Select one or more entity attributes in the list.
4. Use the arrow buttons at the bottom left corner of the list to move the items in the list.
5. Click OK.
