Introduction to the CA-IDMS Data Adapter

The remainder of this manual will use the following terms interchangeably:

CA-IDMS data source	IDMS data source
CA-IDMS Data Adapter	IDMS Data Adapter

When end users issue FOCUS requests to access IDMS data sources, the IDMS Data Adapter generates the most efficient DML calls to satisfy this request. The IDMS Data Adapter retrieves the IDMS records, and FOCUS generates the reports. End users do not need to know Data Manipulation Language (DML) or how to navigate IDMS data sources.

The IDMS Data Adapter supports all FOCUS read-only facilities such as: reporting (TABLE, TABLEF, TABLETALK), creating graphs (GRAPH), statistical analysis (ANALYSE), interactive procedures (Dialogue Manager), and a system editor (TED). You can also report from multiple data sources (using MATCH FILE or JOIN) and create extract files. This is a read-only data adapter, therefore, write-only facilities such as MODIFY and FSCAN are not supported.
