CA Datacom/DB and Datadictionary Components

The following is a list of the CA Datacom/DB and Datadictionary components:

MUF-Multi-User Facility (MUF) provides the ability to access and update databases concurrently from multiple regions or partitions.
CA Datacom/DB-CA Datacom/DB includes all modules installed as the CA Datacom/DB product. A DB Master List defines the operating environment to CA Datacom/DB, including the number of CICS and batch tasks that are accessing the databases.
CBS-Compound Boolean Selection (CBS) is the CA Datacom/DB access facility required for processing CA Ideal FOR statements for CBS access. It analyzes complex database requests and determines the best search strategy.
DB Tables-CA Datacom/DB databases that CA Ideal applications access, are allocated to the MUF region.
DD Tables-Datadictionary tables are CA Datacom/DB databases allocated to the MUF region.
SVC-A supervisor call (SVC) routine handles communication between the CICS and batch CA Ideal regions and MUF.
CICS Service Facility-CICS Service Facility permits CA Ideal applications running under CICS to issue requests to the database through the SVC.
DSF/DDOL-The Service Facility (DSF) for the Datadictionary component of CA Datacom/DB is used whenever CA Ideal accesses the Datadictionary in MUF. DSF is used in a CA Datacom/DB or mixed CA Datacom/DB and DB2 environment.
DDOL, the online Datadictionary component of CA Datacom/DB, is used in CICS. DDOL provides interactive Datadictionary services, using DSF and the CICS Service Facility.
