Chapter 9. PREFERRED DATA ARCHITECTURE CONCEPT > DATA ARCHITECTURES
DATA ARCHITECTURES
Data architectures include the disparate data architecture, enterprise data architecture, preferred logical data architecture, preferred physical data architecture, and the comparate data resource. Each of these topics is described below.
Disparate Data Architecture
The existing disparate data does have an architecture, although that architecture is very disjointed and inconsistent, and is not readily visible. Most disparate data were developed in a probabilistic manner that was seldom planned or coordinated across the organization. The data inventory and cross-referencing processes documented that disparate data architecture, which becomes the as-is data architecture.
