tcVISION Data Capture Methods - Overview

tcVISION offers various data capture methods that can be used to support the required degrees of data latency and manage the amount of data processed. A efficient and secure data synchronization is assured by all methods.

These methods are:

Bulk Transfer

• Efficent transfer of complete databases
• Analysis for data consistency
• Perfectly suited as „Initial Load“ prior to log-processings
• Ideal solution for periodic mass data transfer
• One-step data exchange operation

Note: BULK Transfer is also possible for ODBC, DB2/LUW and ORACLE

Log Processing

• Available for IMS/DB, VSAM, DB2, DL/I, ADABAS, CA-IDMS, CA-Datacom
• Transfer of changed data only for the specified time slot
• perfectly suited for nighttime processing
• perfectly suited for post log-processing

Batch Compare

• Comparison with data snapshots
• Efficient transfer of changed data since last Batch Compare run
• Available for IMS/DB, DL/I, VSAM, DB2, ADABAS, CA-IDMS and sequential files, CA-Datacom
• Automatic creation of deltas
• Secure restart processing after error situations

DBMS Extension

• Realtime and near realtime capturing of changed data
• Change data capturing directly at database level
• Available for IMS/DB, DL/I, VSAM, DB2, ADABAS, CA-IDMS, CA-Datacom
• Secure data storage, even across DBMS restart
