Technology Model-Data

Zachman Definition

"Physical Data Model"

This is a technology constrained, or physical representation of the things of the Enterprise. The representation style of this model would depend on the technology chosen for implementation. If relational technology is chosen, this would be a model of the table structure required to support the Logical Data Model in a relational-style model. In an Object-Oriented notation, this would be the class-hierarchy/association style models.

Select Perspective

A logical data model is designed as part of the Data Architecture Delivery Phase of the Supply Workflow of the Supply, Manage and Consume (SMaC) Service and Component Based Development model.

If physical data models exist in project models, copy them to the Enterprise Model or modify the logical data model created for the System-Data cell.

Select Solution Factory

If project physical data models exist in Select Architect (logical Table Relationship Diagrams) they may be copied into the Enterprise Model using Select Model Copy then collated.

If projects are using an ODBC compliant database, the data schema may be imported into the SCA Enterprise Model using the Select Database Schema Reverser.

If there are no project physical data models, then modify the model created in the SCA Enterprise Model for the System-Data cell.
