Open Systems Transparency - Access to open systems resources from mainframe applications
Ivory® Data Access provides for direct access to any ODBC data source, DB2, or Oracle database residing on a Windows or UNIX/Linux platform, allowing the open systems data to be processed by online (CICS, IMS/DC, etc.) and batch programs on the mainframe. The resulting real-time integration of mainframe applications greatly simplifies bi-directional data exchange and transactional processing in a heterogeneous environment, and may eliminate the need for synchronization of mainframe and open systems data sources.
For example, Ivory Data Access enables a mainframe application to process SQL-Server data or data from an Oracle database. Using simple SQL statements, this data can even be joined with mainframe data (i.e. DB2, VSAM, IMS/DB, ADABAS, etc.). The mainframe program simply calls the API for the Ivory Data Access SQL engine, passes the SQL statement (which can be a pre-defined join between mainframe and open systems data), and specifies connection parameters for the ODBC driver.
The Ivory Data Access API passes the application request to the Ivory Data Access Listener that is running on the MS Windows or UNIX/Linux workstation. The Listener extracts the data using the corresponding ODBC driver and returns the data to the Ivory Data Access SQL engine on the mainframe. If required, the SQL engine will then join the data with any other mainframe file, as specified in the SQL statement.
Ivory Data Access Open Systems Transparency for the mainframe is easy to implement and provides excellent performance when accessing open systems data, with no special network topology requirements.
