Database replication is the process of copying data from a source database to replica databases. This makes data more accessible and improves system fault-tolerance and reliability. Database replication software makes it easier for IT teams and DBAs to duplicate selected database objects and data in order to maintain separate instances of a database for scaling out resource-intensive workloads or improving system availability and resilience. Database replication software can also be used as a database migration tool to upgrade or replace existing servers, distribute and synchronize data across remote offices or users, or consolidate and feed data into a data warehouse or data mart.
If equipped with change data capture technology, database replication software can be employed to create and update a real-time data warehouse, facilitate zero-downtime database migrations, and implement continuous data integration across the enterprise.
If you're in the market for database replication software, then likely you know the answers to basic questions like "what is data replication?" and you know want you want to accomplish with a data replication tool. But because it's a constantly evolving marketplace, you might not know what differentiates best-of-breed solutions from the rest. Although some database vendors provide embedded replication technology, many firms choose to leverage third-party database replication software solutions because of useful features like these:
