Introduction to the CA IDMS DBOMP Transparency › Functions and Modules › Functions

Functions

The transparency acts as a bridge between the DBOMP application program and CA IDMS/DB, as follows:

• Accepts data and processing requests from the calling program
• Converts the data to CA IDMS/DB record formats
• Converts the processing requests to CA IDMS/DB commands
• Passes the converted information to the CA IDMS/DB database management system

Conversely, the transparency also:

• Retrieves data from the CA IDMS/DB database
• Converts the data to DBOMP record formats
• Returns the converted data, along with CA IDMS/DB control information, to the calling program

All communication occurs between the DBOMP program and the transparency or between transparency and CA IDMS/DB. The transparency does not interface directly with the operating system.

The following figure illustrates the CA IDMS DBOMP Transparency processing sequence.
