HostBridge Data Access Modules
For VSAM, DB2, DL/I, Datacom
HostBridge Data Access Modules are optional modules. The Data Access Modules are predefined program objects that can be called within process automation scripts to perform a wide range of operations – virtually anything a COBOL program can do – that may be desired for integration purposes. Both HostBridge and the HostBridge Process Automation are prerequisites of the Data Access Modules. The Data Access Modules enable HostBridge scripts to access and integrate CICS-based resources as follows:
- VSAM Module provides VSAM file access
- DB2 Module provides DB2 database access
- DL/I Module provides IMS database access via the Data Language/Interface (DL/I)
- Datacom Module provides Datacom database access
Because the Data Access Modules read and write directly to their respective resources, developers using HostBridge have the option of invoking CICS transactions through HostBridge or bypassing the CICS transactions and accessing the data behind them directly. Using the objects included in these modules, organizations can include data from an extended set of widely used CICS resources as part of any XML- or services-oriented integration process. Together with HostBridge Process Automation, the Data Access Modules effectively enable the creation of entirely new CICS applications without any modification of mainframe code.
