Segments and Record Types

For each segment defined in a physical DBD, there must be a corresponding record type in a CA IDMS/DB schema. Segments from logical DBDs are exceptions and must not appear in the schema. Logical segments are redefinitions of segments already defined in physical DBDs.

Note: The CA IDMS DLI Transparency syntax generator creates the necessary correspondences in the resulting schema, subschema, and DMCL source. You do not have to code the CA IDMS/DB definitions manually.
