Strategies and Implementation Architectures for Selected Department of Defense Software Repositories

This document reviews proposed alternative strategies and implementation architectures for the integration of three DoD software repositories: the Interim IDEF repository for process reengineering, the Defense Data Dictionary System (DDDS) repository for standard data elements, and the Defense Software Reuse system (DSRS) repository for software components. Due to the lack of obtainable information about user requirements, the sponsor asked IDA to make general assumptions; consequently, an evaluation method and model were developed to evaluate alternative combinations of strategy and implementation architectures. The model served as the basis for recommending the re-use integration strategy with a Hypertext Markup Language database implementation architecture. The benefits of this implementation include providing a relatively fast implementation of the integrated repositories and support for a graceful evolution toward actual integration. A plan for a three-phase implementation approach is also given for the evolution to the new user interface and implementation architectures.
