The relational adapters operate in conjunction with FOCUS to access:

• DB2 under z/OS in TSO and batch.
• Teradata under z/OS in TSO and batch.
• CA-IDMS/DB with the SQL option under z/OS in TSO and batch.
• Oracle under z/OS in TSO and batch.

The adapters are compatible with all currently supported RDBMS releases except where noted. In addition to DB2, Teradata, Oracle, and CA-IDMS/DB tables, FOCUS accesses FOCUS data sources, sequential and delimited data sources, VSAM files, and, with the appropriate adapters installed, many other data sources such as IMS™, CA-IDMS®/DB, CA-Datacom®/DB, ADABAS®, and Model 204®.
