3 SymmetricDS Screenshots:

SymmetricDS is web-enabled, database independent, data synchronization/replication software. It uses web and database technologies to replicate tables between relational databases in near real time.

The software was designed to scale for a large number of databases, work across low-bandwidth connections, and withstand periods of network outage.

By using database triggers, SymmetricDS guarantees that data changes are captured and atomicity is preserved.

Support for database vendors is provided through a Database Dialect layer, with implementations for MySQL, SQL Server, PostgreSQL, HSQLDB, Oracle, and Apache Derby included.

Synchronization can be configured to push data (trickle-back) or pull data (trickle-poll) at an interval. SymmetricDS allows for 2-tier and even n-tier synchronization, such as the following:
· A farm of web server nodes fronting an enterprise-class general office database
· A handful of regional servers for synchronizing from the general office to remote geographical areas
· 1000(s) of store server nodes using a departmental class database to sync with a regional node
· 10(s) of Point of Sale (POS) register nodes using an embedded database to sync with a store server

Deployment options include the following:
· Web application archive (WAR) deployed to an application server such as Tomcat, Jetty, or JBoss
· Standalone service
· Embedded in an application
