TapData offers a robust solution for real-time data integration. Modern businesses rely on data synchronization to enhance collaboration, reduce errors, and boost productivity. Accurate data ensures higher quality across enterprises by cutting down on duplicates and inconsistencies. Change Data Capture (CDC) plays a pivotal role in this process. TapData's CDC database technology captures changes in the source system within seconds, enabling seamless data synchronization. This technology supports various databases, including change data capture Oracle, DB2, kafka, and SQLServer etc.., ensuring efficient data management.

Understanding Change Data Capture (CDC)

What is CDC?

Definition and basic principles

Change Data Capture (CDC) identifies and captures changes in a database. This technique allows real-time or near real-time data updates. CDC ensures that data remains consistent across different systems. The primary goal of CDC is to track modifications without impacting the performance of the source database.

Historical context and evolution

CDC has evolved significantly over the years. Initially, batch processing was the standard method for data synchronization. This approach had limitations, such as high latency and resource consumption. Over time, CDC transitioned to real-time streaming. This shift enhanced the efficiency and accuracy of data integration. Businesses now gain powerful insights from timely data updates.

How CDC Works

Mechanisms of capturing data changes

CDC employs various mechanisms to capture data changes. One common method involves monitoring database logs. These logs record every change made to the database. Another approach uses triggers. Triggers are special procedures that activate when specific events occur in the database. Both methods ensure that all changes are captured accurately.

Types of CDC (log-based, trigger-based, etc.)

CDC can be categorized into different types based on the capture mechanism:

Log-based CDC: This type reads the database logs to identify changes. It is efficient and minimally intrusive.
Trigger-based CDC: This type uses database triggers to capture changes. It can impact performance but provides detailed change information.
Timestamp-based CDC: This type compares timestamps to detect changes. It is simple but may miss some changes if not configured correctly.

Benefits of Using CDC

Real-time data updates

CDC enables real-time data updates. This feature ensures that all systems have the most current data. Real-time updates improve decision-making and operational efficiency.

Reduced data latency

CDC reduces data latency by capturing changes as they happen. This approach eliminates the delays associated with batch processing. Low latency is crucial for applications requiring timely data, such as financial services.

Improved data accuracy

CDC enhances data accuracy by ensuring consistency across systems. Accurate data reduces errors and improves the quality of business insights. TapData's CDC database technology excels in maintaining high data accuracy.
