Change Data Capture


Change Data Capture (CDC) is a function within database management software that makes sure data is uniform throughout a database. CDC identifies and tracks changes to source data anywhere in the database, and then applies those changes to target data in the rest of the database.

CDC can be applied in any database, though it is most commonly used in data warehouses, where data synchronicity is vital.
