Data Modeling Concepts

While data modeling can be complex, this Methods Guide will help you understand data modeling and its uses. If you are just a beginner, you will understand enough to put the methods to work for you by the time you finish reading this guide.

Overall, this guide has the following purposes:

• To provide a basic level of understanding of the data modeling method used by CA ERwin DM that is sufficient to do real database design.
• To introduce some of the descriptive power and richness of the IDEF1X and IE modeling languages supported and to provide a foundation for future learning.
• Experienced IDEF1X or IE users can use this as a guide to the features of IDEF1X and IE supported, and the mapping between these methods.
