Concluding Remarks
Publisher Summary
This chapter presents a data model that provides a framework for analyzing business requirements, provides a data model of some detailed areas that shows how business terms can be incorporated into a data model, and is easily extensible, either by adding entity types or reference data. From this, it can clearly be seen that the model is coherent and cohesive, as well as extensible in a regular way; all desirable properties in a changing world. Working things out properly is actually the fastest way to the right answer, plus it helps to assure that one has the right answer. In data modeling, it is not the time it takes to produce a model that determines the effort it takes, but how many times the model has to be redone before it sets right. The result overall is improved consistency, especially when one has a team of data modelers, and a reduction in errors and rework. All of this leads to high quality data models that meet the information requirements of the business.
