Presentation
How the Data Model is Integrated into Enterprise Architecture
The analogy to the game of chess is useful when following the Zachman Framework to design Enterprise Architecture. Both endeavors require skill, experience and patience. The Zachman Framework’s prescribed design artifacts are "chess pieces" that must be deftly coordinated. But consider which piece dominates the game and provides the most benefit to the Enterprise Architect. Among the pieces that populate the Zachman Chessboard is the Data Model. As the Data Model evolves from Conceptual to Logical to Physical, it facilitates the development of Business Objectives, Formal Business Rules and Technical Requirements. These in turn influence all other design artifacts. For this reason, the author, who with over twenty years of successful implementations, suggests that the Data Model is the Queen of the Zachman Chessboard.
