The Data Element entity
The purpose of the Data Element entity is to identify and describe all the pieces of information that are used by the applications.
A Data Element is a unit of data that is considered as elementary during at least one stage in the development of a project.
For example, during the project analysis, the information Date
of operation
can be traced. During implementation, it can be broken
down into year, month, and day of operation. Each one of these four
basic units of data is defined as a Data Element:
- Date of operation
- Year of operation
- Month of operation
- Day of operation
