Change Data Capture (CDC) is a replication solution that captures database changes as they happen and delivers them to target databases, message queues, or an extract, transform, load (ETL) solution such as InfoSphere® DataStage® based on table mappings that are configured in the Management Console graphical user interface.

CDC provides low-impact capture and fast delivery of data changes for key information management initiatives including dynamic data warehousing, master data management, application consolidations or migrations, operational BI, and enabling SOA projects. CDC also helps reduce processing overhead and network traffic by sending only the data that has changed. You can perform replication either continuously or periodically. When data is transferred from a source server, it can be remapped or transformed in the target environment.

InfoSphere CDC for z/OS® is intended for organizations that want to replicate DB2® data to or from a z/OS system. More specifically, InfoSphere CDC provides the necessary support to implement data distribution, data sharing, or data transformation.

Front-end functionality for InfoSphere CDC for z/OS is provided through Management Console. Management Console allows you to work with tables and databases in source and target environments in order to configure, start, and monitor replication. Management Console communicates with InfoSphere CDC to support the sending and receiving of DB2 table data.
