Question: If you are current on the owner of a set, what is the difference between an obtain next and obtain first?

Question: What is the difference between local and central version operating modes?

Answer: In local there is no IDMS System running above the DBMS. It's the more efficient mode but lacks the recovery and integrity facilities of the central version (CV) control program. In CV many application programs access the database through a single copy of the DBMS. Source:
Question: When you are obtaining next within a set and get a end of set return code, on what record are you now current?

Answer: You are current on the owner. Source:
Question: What is a bind?

Answer: A bind associates record types with the program work area; for run unit and records it is the first command issued in the program. Source:

Question: What is currency?

Answer: Currency is the location within the database during run-unit execution.
There are four levels of currency:

current of record type is for the most recent of each record type;
current of record set is the most recent within each set and current of area is within each area.
Question: What is an OOK-Rec?

Answer: An OOK-Rec is a one of a kind record set, used to get to another record set . Source:
Question: So manual and automatic are the connect options for a set. What are the disconnect options?

Answer: Mandatory and optional. Source:
Question: What is the difference between a schema and a subschema?

Answer: The schema is the physical arrangement of the data as it appears in the DBMS. The subschema is the logical view of the data as it appears to the application program. Source:
Question: What is the meaning of the return codes 0307 and 0326?

Answer: 0307 is end-of-set and 0326 is record not found. Source:
Question: What sets will the stored record connect to?

Answer: It will connect to all sets where it is defined as an automatic member. The store requires that currency be established for all these set occurrences. Source:
Question: What does a store statement do?

Question: Distinguish among erase, erase permanent, erase selective and erase all?

Answer: Erase cancels the membership of a record in specific set occurrences and removes only the named record.
Erase permanent removes the specific record and all mandatory occurrences it owns. It disconnects all optional members.
Erase selective removes the record, all mandatory members and all optional members not connected to other sets. It disconnects those that are connected.
Erase all removes the specified record and all the mandatory and optional records it owns.
