POSC Specifications Projection Meta Model
Version 2.3


This is the documentation for the logical entities of the meta data schema and for the projected relational tables that are used by the POSC Compatibility Layer. The POSC Relational Projection Tool creates a population of the tables in order to describe how a Logical Data Model was projected to create the corresponding Relational Implementation.

The only change from Version V2.2 is to add four attributes to entity epic_type and two attributes to entity type_def. These attributes represent the addition of a possible fifth and sixth parameter to Epicentre data types. This was required by changes to the Epicentre Modeling Methodology Version 2.3.
