Designing a local view

A local view is a description of the data that an individual business process requires.

It includes the following:

• A list of the data elements
• A conceptual data structure that shows how you have grouped data elements by the entities that they describe
• The relationships between each of the groups of data elements

Definitions: A data aggregate is a group of data elements. When you have grouped data elements by the entity they describe, you can determine the relationships between the data aggregates. These relationships are called mappings. Based on the mappings, you can design a conceptual data structure for the business process. You should document this process as well.
