ASSET_A_171: Life Cycle Modeling Lessons Learned This document presents lessons learned from experimentation with the Distributed Computing Design System (DCDS) and building repositories with Digital Equipment Corporation's CDD/Dictionary Operator tool, CDO. This experimentation leads to a discussion on object-oriented principles and analysis which sets the foundation for explanations of the Waterfall, Spiral, and Rapid Iterative models, a Framework Information Model (FIM), and a SEE Information Model (SIM). With this foundation, the SEE framework type hierarchy and the Life Cycle Data Model (LCDM) are presented. Logical structuring of PARTITIONs, COLLECTIONs, and CONTEXTs clarify a user's visibility into the SEE framework and use of the LCDM. The LCDM is exemplified further with the instantiation of objects created during the DCDS and CDO experimentation. The Appendices contain CIS, IRDS, ATIS, and the SEE framework type hierarchies, detailed explanations of logical structuring, definitions and placement into the SEE framework type hierarchy.
