The common approach to creating enterprise architectures is the development of a set of formal, formatted and standardized architecture products. Taken together, the products provide a full description of the enterprise. This volume focuses on a data-centric alternative to the commonly used product centric approach. As the name implies, the data-centric approach to architecture development centers around defining an enterprise by defining data elements that describe the components and characteristics of the enterprise. These data elements can be grouped into seven different information categories: organizations and organizational nodes; systems and system nodes; information and data; interrelationships (including interfaces and information exchanges); operational concepts; missions, functions, processes, tasks, and activities; and rules.
