Description and Analysis Methods of Information System Architecture Based on DODAF

DOD architecture framework (DODAF) can describe not only operation activities in military field, but also composition of system in non-military field. By studying DODAF, description and analysis methods of it are abstracted in this paper, and information system architecture framework is proposed from view of non-military. In this framework, fourteen products that describe information system architecture are defined, and eight products in them are described emphatically through the Unified Modeling Language. Finally, association and map relationships among products are analyzed and suggestions about building sequence of products are proposed.
