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)
"Triggered by TR"

The description of object type Field is organized under the following headings:

Maintaining Objects of Type Field
Defining Basic Attributes of Fields
