Abstract: A memory is provided for storing data for access by a database program being executed on a computer system for evaluating an enterprise architecture. A data structure is stored in the memory with the data structure including information resident in a database used by the database program. The data structure includes a work flow model, an information model; and a technology model. Each model includes a plurality of entities linking the models together. The computer system executes the database program for evaluating linkages between entities and how architectural changes to the enterprise affect the enterprise architecture by accessing the memory storing the data structure, and generates a result indicative of the linkages between entities.
