+MyWind is a MySQL version of the Microsoft Access 2010 *Northwind* sample database.
 
-The Northwind demo database provided with Microsoft Access is an excellent tutorial schema for managing small business customers, orders, inventory, purchasing, suppliers, shipping, and employees. My problem was that I wanted to experiment with it using [MySQL](http://www.mysql.com) and the [Yii Framework](http://www.yiiframework.com).

Whoever walks this way, please figure this out and deal with it appropriately.
