With Predict, data definitions can be documented for a wide variety of data storage systems and for use with different programming languages. Field definitions are documented with objects of type Field.
In the predefined Predict metastructure, a field can have passive and active associations of the following types:
| Valid passive association: | "Belongs to FI" (default passive association, mandatory) |
| Valid active associations: |
"Is verified by VE" (default active association,
up to 50 verifications may be linked) |

The description of object type Field is organized under the following headings:
| Maintaining Objects of Type Field |
| Defining Basic Attributes of Fields |
| Defining Derived Fields |
| Defining Additional Attributes of Fields |
| Field Maintenance |
| Field Retrieval |
