The full form of CDC computer depends on the context. Here are two possibilities:
-
Control Data Corporation (CDC): This was a major American computer company founded in 1957 by William Norris. CDC was known for producing some of the fastest supercomputers in the world during the 1960s and 1970s.
-
Change Data Capture (CDC): In the realm of databases and data management, CDC stands for Change Data Capture. As the provided reference states, Change Data Capture is a software process for identifying and tracking changes to data in a database.
Change Data Capture (CDC) Explained
Change Data Capture is crucial for data replication, data warehousing, auditing, and real-time analytics. Here's a breakdown:
- It identifies and tracks changes (inserts, updates, deletes) made to data within a database.
- It provides real-time or near-real-time data movement. This allows for continuous processing and moving of data as new database events occur.
- CDC enables applications to react instantly to data changes, improving responsiveness and efficiency.
For example, consider an e-commerce platform:
- When a customer places an order, CDC captures this change.
- This triggers updates to inventory management systems, shipping notifications, and sales dashboards.
- All these updates happen almost instantly, providing a seamless experience.
Key Benefits of CDC
- Real-Time Data Integration: Enables immediate updates to data warehouses and other systems.
- Reduced Load on Source Systems: By capturing only changes, CDC minimizes the performance impact on production databases.
- Improved Data Accuracy: Ensures that data in target systems is consistent and up-to-date.
- Simplified Auditing: Facilitates tracking data changes for compliance and security purposes.
