Record and Set Representations

In an CA IDMS/DB database, a VSAM ESDS data set corresponds to a system-owned indexed set with a set order of SORTED (on db-key) or LAST. To represent a VSAM ESDS in an CA IDMS/DB database, you must include the following definitions in the schema:

• A record type whose description corresponds to the ESDS record
• An indexed set whose owner is SYSTEM and whose member record is the record type described above
• A set order of SORTED (on db-key) or LAST
