Supporting date time and timestamp values in MySQL can be challenging while replicating from a another database that uses different rules.   In this article we walk through some issues with syncing date time values into MySQL and how to filter them out so that your replication stay on track. 

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.
