What SQDR Does

SQDR provides data availability and secure data replication across multiple databases in real-time, regardless of host or target system location.

The solution moves data easily among your core relational databases, across firewalls, to other teams, or to the cloud.

IT teams experience an elegantly designed solution with minimal host impact that takes only hours to configure, not days or weeks.

SQDR is an Ideal Solution

No-programming interface makes it easy and affordable to implement.

Simple installation with graphical interface, configuration wizards, and advanced data modeling tools make product setup and operation straightforward, with no programming or consultants needed. The SQDR Driver bundle includes licenses for high-performance ODBC drivers for IBM Db2, Oracle, MySQL and Microsoft SQL Server. Depending on your requirements, snapshot, incremental, and bi-directional replication are available. A single SQDR license is needed for source and destination databases, regardless of how many tables are replicated, delivering extremely low total cost of ownership.

Speedy and agile.

Replicate multiple tables concurrently in heterogeneous environments, such as between IBM Db2 or Oracle and Microsoft SQL Server or between IBM Db2, Oracle, Informix, and MySQL. The SQDR solution provides reliable, high-speed, affordable replication for any relational database accessible via ODBC. SQDR leverages native data-loading functions, and exploits multithreaded processing to provide fast, reliable performance for replicating multiple tables concurrently.

Powerful, flexible, and secure.

StarQuest gives you greater control by allowing you to choose replication of data you want with both vertical and selected horizontal partitioning. Replace existing tables or merge on a row-by-row basis. SQDR also supports derived destination columns and data transformations, including automatic and customized conversion and selection of dates, views, indexes, and constraints. While flexible, SQDR fully enforces enterprise security mechanisms by integrating with both SQL Server/Windows security and the native security of your Db2 system.

Deployed on a thin server, ultra-low footprint.

SQDR can process millions of changes per hour at a near zero footprint, avoiding any burden on your production or host databases. With no need to install or upgrade software on the source or target systems, deployment is fast and downtime is zero for migrations or upgrades. Our database-neutral SQDR data replication tools give you the highest performance at the lowest impact.

Provided under flexible licensing.

StarQuest provides an affordable data replication solution, especially compared to other enterprise-level replication products. The SQDR license model is independent of the number of cores of either the source or destination DBMS - so customers only pay for the capacity required to support their replication processing load. Development/QA and Disaster Recovery (DR) pricing discounts are also provided.
