Data Model Tool

The Data Model Tool lets you add, change, and delete data in a graphic style. Use this tool to produce the central diagram in data analysis. The ERD lets you perform the following tasks:

• Graphically show the types of data (entity types)
• Show connections (relationships) between entity types
• Record data characteristics (attributes)
• Record data uniqueness (identifiers)
• Logically group entity types into subject areas

This graphic tool is useful in initial data analysis, and when you need to review the data with users who may not be familiar with it. For additional information about the graphic tool, see the chapter Data Model Objects.

A Sample Entity Relationship Diagram is shown next.
