The fact that iSeries has reasonably-sophisticated databases does not guarantee that you will automatically achieve a sophisticated and reasonable database design. To achieve the design goals given above, you will need to discover the correct structure of your data, in particular to examine it for all forms of redundancy. To do this, the techniques of data modeling may be used. Data modeling provides a formal method for transforming business goals into a database design as follows:
CA 2E includes a data modeling tool that enables you to design a database, and then implement it.
Note: A full discussion of how to turn a business model into a data model, or a data model into a database design, is beyond the scope of these standards. There are, however, various points about the database of iSeries that analysts new to the machine may find useful, and also a few guidelines that programmers new to analysis may find helpful.
