Release 10.1A: OpenEdge Development:
Progress Dynamics Repository Reference

Repository model

The Repository for Progress Dynamics Version 2 was designed with the ERwin database modeling tool. The model, icfdb.er1, and its template, icftemplate.ert, ship with Progress Dynamics. You can locate these files in DLC\src\icf\db\icf\doc. You need ERwin Version 4.1 SP2 (Build 4.1.2771) to open these files.

The table figures used in later chapters are taken from the Progress Dynamics Repository model. The figures use the Information Engineering (IE) notation form. These figures show the way various cardinalities are depicted in IE notation.

Figure 1–1 shows the notation for “One to zero, one, or more” cardinality.
