Change data capture (CDC) lets you identify and capture changes to data in a source system in real time. Find out what the best change data capture tools are here.
Data comes from many sources — applications, data streams, emails, etc. However, your ability to draw insights from this data is hampered unless you have a system in place to capture this data and make it ready for analytics.
Using the right CDC tool can help.
In this article, we’ll look at what CDC is and the benefits that CDC tools offer. We’ll also provide a list of the best CDC tools to help you find the right one for your company.
What is change data capture (CDC)?
Change data capture (CDC) is the process of identifying changes in a source database and replicating them to a target system like a data warehouse. It transfers data in increments as new database events occur instead of extracting or replicating entire datasets.
Why use CDC tools?
While you can hand-code CDC processes, it can be extremely challenging. Plus, you’ll have to manage the code yourself, which means higher maintenance costs.
Here’s why you should use CDC tools instead.
Accelerate reporting and analytics
CDC tools only move and replicate data changes. This enables faster data movement between databases, which improves your business intelligence capabilities.
Faster reporting helps companies make informed decisions more quickly. For example, manufacturers can instantly capture data changes from machines and determine which ones are slowing down production.
Eliminate data silos
Data silos create barriers to information sharing, which affect collaboration between departments and prevent business leaders from getting a holistic view of their operations.
CDC tools can help you eliminate data silos. One way they do this is by integrating data from different sources into a target database.
Sync your data to multiple systems
Ninety-five percent of businesses have seen impacts due to poor data quality. This can happen when teams work independently on the same datasets.
CDC allows you to sync data across multiple systems regardless of their location. This improves data availability and ensures that your team is working on the same data.
Reduce the burden on operational databases
Analytical queries require many computing resources. CDC tools enable companies to replicate data to an analytical database that analysts can query without overloading operational databases.
In short, CDC tools help you create a more modern data stack. But you need to choose one that can support your business requirements.
