Data Replication and Synchronization of Mainframe Data

The powerful data mapping functions of tcVISION provide a detailed overview of the mainframe- and Open System-data to the tcVISION user. It is no longer necessary to always involve mainframe and database experts. 
Batch processes are available to automatically create the mapping structures. For VSAM files the data mapping is performed based upon copybook information. For IMS/DB databases the production PSB and DBD load modules are evaluated. 
In the case of ADABAS and CA-Datacom, the Data Dictionary of the database is evaluated. For CA-IDMS, SCHEMA definitions are the source for the meta data. The field structure definitions can be easily viewed using the tcVISION Control Board, hence allowing an easy selection of the meta data necessary for the changed production data.
The structure information is stored in the tcVISION Metadata Repository. The tcVISION Repository is the central database for all structure information and data formats used by the installation. The Repository can be hosted by any relational database management system like DB2, ORACLE or MS SQL Server, hence becoming an integral part of customer specific processes.
tcVISION prepares the changed data for the target system based upon rules and specifications made in the Repository (reformatting, conversion, transformation etc.) These specifications can easily be done using the tcVISION Control Board application. The replication rules (1:1, 1:n, n:n, etc.) are also part of the Repository. Maintenance of these rules is also performed with the graphical tcVISION Control Board application.
