DISTRIBUTED COMPUTING DESIGN SYSTEM DESCRIPTION DATABASE

OUR OVERALL GOAL IS TO COMMERCIALIZE THE DISTRIBUTED COMPUTING DESIGN SYSTEM (DCDS) METHODOLOGY (PREVIOUSLY DEVELOPED BY TRW FOR THE US.S. ARMY BMDATC). DCDS SUPERSEDES CURRENT METHODS WITH REQUIREMENTS-TO-CODE SUPPORT FOR REAL TIME DISTRIBUTED SYSTEMS. THE SYSTEM DESCRIPTION DATABASE (SDD) IMPLEMENTS AN UNDERLYING REPRESENTATION BASED ON ELEMENT RELATIONSHIP ATTRIBUTE AND GRAPH MODEL OF COMPUTATION PRINCIPLES. OUR PHASE I OBJECTIVES FOCUS ON THE PROTOTYPE DEVELOPMENT OF A SDD DATABASE WHICH CONTAINS THE COMPOSITION OF SYSTEM AND SOFTWARE ELEMENTS, THEIR RELATIONSHPS, AND ATTRIBUTES (SUCH AS UDF COVERSHEET, SOFTWARE MODULE METRICS, INPUT/OUTPUT DEFINITIONS, TRACEABILITY POINTERS, ETC.). INTERNAL DATA STRUCTURES PROVIDE REPRESENTATIONS THAT PERMIT GENERATION OF GANE & SARSON, YOURDON, STATE TRANSITION, N-SQUARED, AND HIERARCHY CHART DIAGRAMS. SDD SUPPORT SYSTEMS AND SOFTWARE ENGINEERING BY PROVIDING: COMPUTER SOFTWARE CONFIGURATION ITEM (CSCI) DOCUMENTATION, CHANGE TRACKING MECHANISMS EMBEDDED IN THE DATA STRUCTURES, MAINTENANCE OF SOURCE REQUIREMENTS, AND SUPPORT FOR THE FIVE INTERLOCKING SPECIFICATION LANGUAGES COMPRISING THE DCDS METHODOLOGY.
