One of the most common replication patterns we see here at JumpMind is a three tier setup with a central, regional, and site group.  Retailers commonly use this approach with groups named: corp, store, and register.   However we often see setups that try to reduce this approach down to two tiers with a similar set of functionality.  Deciding between a two or three tier approach can be tricky and each may have advantages and disadvantages based on your needs.  This article will help to explain these differences and hopefully help in making the best design choice for your needs.

Maybe it is because your current database platform does not support the functionality you need for a big data project, or maybe you require features that are in a more recent database version. Whatever the reason, migrating a database is often a very valuable and necessary task that allows your business to both keep up with changing technology as well as lower the overall costs of running old systems.

SymmetricDS has been designed around the user upon numerous feature requests from our clients and the open source community. As a result there are a lot of different factors that play a role in how to use it within your project. At a higher level though here are some of the best practices we find should be considered for nearly all implementations.

In the SymmetricDS 3.9 release, many user interface changes have been made to improve usability and display more information. One area of focus for these improvements are within the Incoming and Outgoing Batch screens. These changes provide a cleaner and more uniform representation of the data displayed on both screens.

SymmetricDS has the ability to sync between databases and between files. With the 3.9 release, SymmetricDS will link the two which will enable you to route data from a CSV file into a database table. This will make it significantly easier to directly sync your data. In this article, I will walk through the steps to replicate CSV data to a table.
