As firms collect increasing quantities and varieties of data, their IT departments are under pressure to process and deliver fresh data to line-of-business users faster than ever before. In order to meet the data delivery needs of their organization, they're leveraging a combination of data integration approaches to improve data availability and enable real-time data synchronization across the organization. Change data capture is one of those approaches.

Improve Efficiency and Facilitate Real-time Data Integration with Change Data Capture

What is change data capture? Change data capture is a technology used for identifying and capturing changes made to data in a database and—depending on the tool employed—delivering those changes to another database or other type of data repository. By allowing you to capture and extract only changed data, change data capture eliminates or reduces the need for batch windows, replacing bulk load updates with continuous streaming or incremental loading of data. Change data capture helps you improve efficiency by reducing redundant data replication and delivery, reducing data warehousing costs and facilitating real-time data integration across your data stores.

Finding the Right Change Data Capture Solution for Your Needs

Although some database vendors offer embedded technology for change data capture, many do not or have ceased supporting built-in CDC—as is the case with Oracle Change Data Capture. And so, in order to implement change data capture in Oracle and many other database environments, firms must find a robust and reliable third-party CDC solution.

Finding the right change data capture solution for your particular requirements can be difficult. Here are some key capabilities to look for:

  • Ability to capture changes from many types of data sources on different platforms, including legacy systems like DB2 mainframe, and interoperate with your existing ETL and EAI tools
  • Use of non-intrusive technology that reads changes from database transaction logs or journals to minimize the impact of capture processes on the performance of your source systems
  • Support for change filtering to further improve efficiency and flexible data delivery options to accommodate the latency requirements of your applications
