  In today’s data-driven business environment, the overriding concern is data breaches. Organizations try to solve this issue by ramping up data security to protect historical data. Hence, the top database platforms like Microsoft SQL Server and Oracle database have introduced various solutions like timestamps, complex queries, triggers, and data audits. In 2005, SQL Server launched “after date”, “after delete”, and “after insert” features for SQL Server Change Data Capture ( CDC). But that only partially solved the issue. In 2008 SQL Server introduced a modified version of CDC that turned out to be more effective. CDC helps to track and capture all the changes that are made on the SQL Server database tables without extra programming. In the initial stages up to 2016, SQL Server Change Data Capture was active only in the Enterprise Edition but now, it is a universal feature in the SQL Server. CDC monitors the Insert, Update, and Delete operations in the table of a database. Al...

  Replication is the process where data is continually copied electronically from one database in a server or computer to another database in another server or location. This results in a distributed database where users can access necessary data without interfering in the work of others who are accessing the same data or server from the same or a different place. However, the replication process is not simple and can be precisely done only by following the right processes and using the most optimized tools. To make the process a success, the best database replication tool should be used. There are fundamentally three types of such tools and organizations should choose one that matches their need. Snapshot database replication tool – It is a simple process where a “snapshot” of the data in one server is taken and moved to a separate server or a database in the same server. After the first synchronization is completed, the tool refreshes the data in the published tables over f...
