dc.description.abstractData is a resource in both its physical and descriptive aspects. Both should be managed as any other major organizational resource. A data dictionary system is a formal method to handle ana control the data information. It enables management to enforce data definition standards; it supplies information about the creation, usage and relationships of data; it eliminates the data redundancy and data inconsistency; it aids the security of sensitive data definitions against unauthorized use. In this paper, we first introduce the data dictionary system concept and discuss the Entity-Category-Relationship (ECR) model. Then a data dictionary design based on the ECR model is presented. Both the method and examples of the schema and the data dictionary files are presented. The data dictionary files creation, contents, function and relationships are discussed. In addition, function procedures which help the users to get the information from the data dictionary files are presented.
