The process will begin with a conceptual model, development into a rational model and conclude which has a Actual physical model. Each variety of more info data design is mentioned in additional depth in subsequent sections:
Sensible data versions don’t specify any technological system prerequisites. This phase is often omitted in agile or DevOps tactics.
