Summary

In this chapter, we've looked at building the conceptual data model of the system. The process begins with a review of all source materials to identify the data items used by the system, which are then organized into a set of entities. The relationships between the entities are reviewed, and then each individual entity and its attributes are analyzed.

In the next chapter, we'll look at translating the conceptual model into the physical database schema that will be implemented against the chosen database engine.
