Anchor record
In addition to the records defined in the schema DDL, UDS/SQL automatically generates
one anchor record for each SYSTEM set. In SYSTEM sets, the anchor record assumes the
function that the DBTT of an owner record type performs in a normal set. The anchor record
contains its own act-key as well as the act-keys of the tables belonging to the SYSTEM set.
It is extended by SCD if the records of the SYSTEM set are stored as a chain.
