Approach for Making JCAPS Conformant to the C4ISR Core Architecture Data Model (CADM)

摘要

Based on data requirements from the DoD C4ISR Architecture Framework Version 2.0 and from numerous architecture initiatives of the Military Commands, Services, and Agencies derived from the Framework, the C4ISR Core Architecture Data Model (CADM) provides a specification of architecture data expected to be common among two or more DoD architecture developers. The CADM fully supports all the architecture products specified in Framework 2, including all of Appendix A of the Framework. The CADM supports additional architecture data requirements arising from Command, Service, and Agency architecture databases and data models. Part of the CADM has been extended to form the basis of a new Army Systems Architecture Database. The Joint C4ISR Architecture Planning/ Analysis System (JCAPS) has been under development for 3 years and uses part of the CADM in its database design. The specific objective addressed by this IDA report is to determine what changes are required of JCAPS to assure full CADM 2. 0 compliance. The report identifies features of the JCAPS 2.1 data model that are seen as barriers for achieving CADM conformance and proposes a new data model to be used for future JCAPS implementations. This new model is electronically embedded in the CADM data model as a view with 107 CADM entities, with additions provided by Army (14 entities) and Navy extensions (1 entity) to the CADM, as well as by JCAPS itself (21 entities and 90 additional attributes for CADM entities). The resulting data model has 143 entities and supports 100 percent of JCAPS 2.1 data requirements. The document provides annexes with data model diagrams describing JCAPS 2.1, the recommended data model, the traceability tables that map JCAPS 2.1 to the recommended data model, and summaries of work completed by the JCAPS Data Standardization Working Group in 1999 that made partial recommendations for CADM conformance.
