Learning from the Data Model
Clare Churcher · Apress eBooks · 2012
In the previous chapter, we attempted to extract the essential tasks involved in a real-world problem and express them with use cases. We also made a first attempt at determining the data that are necessary to support those tasks and formed an initial data model, which we depicted with a class diagram. In this chapter, we look more closely at the data model to see how it can further our understanding of a database system. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
