0580 Data Dictionaries¶

At the start of a data project, it is often necessary to describe the types of data that is needed. This is called a data specification.
DataField entities are used to model specific data fields required by the data project. As the project progresses, data schemas are defined to describe how data is organized in the different data assets used by the project.

The data dictionary maintains lists of pre-defined, reusable data fields.
