Data Replication: How to Teach Old Data New Tricks

What can be done when the CEO demands that transactional data generated and stored on legacy RDBMS be made available to apps that only work with modern data stores? Homegrown solutions coded in dated languages are not practical and data migration projects are inevitably time-consuming and expensive. So what’s an IT pro to do? Consider data replication software.

Heterogenous data replication solutions ensure legacy data flows continue uninterrupted while mirroring data to modern DBMS where data can be accessed by the desired applications. This is achieved by creating a unified copy of data on an intermediate server and then utilizing change data capture to ensure that the source and target (master/slave) databases are synchronized in real-time. Virtually all processing occurs on the intermediate server, minimizing load and ensuring that a unified copy exists in case of a failure on either the source or target database.

High-quality data replication solutions such as StarQuest’s SQDR even run bi-directional replication pairings in real-time to enable near-instantaneous reporting and data analysis. If you solution has cutting-edge features, it can also be used as a real-time ETL tool, a key component of your disaster recovery strategy, and as a cost-saving method for reducing queries on legacy systems.
