Describing a Group of Fields


Certain fields in a data source may have a one-to-one correspondence. The different groups formed can be related to one another. For some types of data sources you can define a subset, a logical view of a group. You can identify these groups and the relationships between them by using attributes in the Master and Access File, as well as related facilities, such as the JOIN command.

This section describes the relationships of fields and how to implement them using Master File attributes. If your type of data source also requires an Access File, see the appropriate data adapter documentation for supplementary information about defining groups and group relations in the Access File.

For Maintain Data: Dynamic joins (SEGTYPE DKU), and recursive joins are not supported. Static joins (SEGTYPE KU) are supported.
