MySQL is a popular open-source RDBMS (relational database management system) and offered under two different editions: the open source MySQL Community Server and the proprietary Enterprise Server. The MySQL Enterprise Server is differentiated by a series of proprietary extensions which install as server plugins but is built from the same code base. In databases, change data capture (CDC) is a set of software patterns used to determine and track data that has changed so that action can be taken using the changed data.
