470 Chapter 9 ■ Using the Patterns

What Is in This Chapter?

First, we describe a scenario that will be repeated and built upon throughout

the chapter. This scenario evolves as circumstances change in each section.

Then in the rest of this chapter, our intention is to address what we believe

are some of the most common circumstances in which people could use the

patterns to build data models. These include the following:

Prototyping and scoping data models. These patterns could be used

for prototypes, as part of a scope statement, and in other circumstances

where there is a need to specify information requirements. These are

examples of using the patterns to develop very specific data models and

generally are used for gathering and validating data requirements with

business-oriented audiences.

Application data models. When there is a need to develop an applica-

tion system, these patterns can be used to develop a data model for the

application.

Enterprise data models. This section addresses the need for using the

patterns to develop data models that reflect the needs of the enterprise as

a whole. Also, we show a specific approach to enterprise data modeling

that provides alternative data model constructs to model the same type

of data. Thus, some data requirements are modeled using both specific

and generalized patterns, providing a choice to applications ...
