Where do data models fit in the Software Development Life Cycle (SDLC) Process?

Data Model SDLC Relationship Diagram In the classic Software Development Life Cycle (SDLC) process, Data Models are typically initiated, by model type, at key process steps and are maintained as data model detail is added and refinement occurs. The Concept Data Model (CDM) is, usually, created in the Planning phase.   However,  creation the Concept … Continue reading Where do data models fit in the Software Development Life Cycle (SDLC) Process?
