Open Source Multi-Channel Order Management

Webyog recently released SQLyog Enterprise 4.1. If you are a SMB trying to figure out a way to keep your internal odbc db in sync with an online MySQL server, this is the tool for you. For example, you can easily keep your Dydacomp Mail Order Manager db in sync with your web site. Or feed your UPS WorldShip Database information from your osCommerce website, and then automatically upload the UPS tracking number back to your site once shipped. The syncronization can be setup via a easy to use scheduler. You don't even need shell access to your server to set it up, you can simply upload the provided PHP interface file to your webspace, and then easily setup a HTTP tunnel directly to your database.

There is a free version available with less features, and the SQLyog Enterprise version which costs $49 for a non-commerical use, and $99 for commerical use.
