In the Data driven world, companies who have access to data real time have a significant advantage on their competitors who do not. One of the things that prevents IT to provide real time data is the time it takes to extract data from legacy systems and load into the Analytical systems.

As such, loading all the data into these systems every time is not efficient use of the computing resources and it also takes longer to get the data to the users. This is where Change Data Capture (CDC) plays a significant role in integrating data faster into target systems.
