Change data capture (CDC) is a set of software design patterns used to determine the data that has changed in a database so that action can be taken using the changed data.

Changed Data Capture (CDC) helps identify the data in the source system that has changed since the last extraction. With CDC, data extraction takes place at the same time the insert, update, or delete operations occur in the source tables, and the change data is stored inside the database in change tables. The change data, thus captured, is then made available to the target systems in a controlled manner.
