Recommendations for logical data modeling

To build sound data models, analysts follow a well-planned methodology.

Follow these recommendation for building quality data models:

• Work interactively with the users as much as possible.
• Use diagrams to represent as much of the logical data model as possible.
• Build a data dictionary to supplement the logical data model diagrams.

  A data dictionary is a repository of information about an organization's application programs, databases, logical data models, users, and authorizations. A data dictionary can be manual or automated.
