This loads the Northwind database so that you can use it to test out things that require some normal, relational data. Feel free to use this as sample data for any other applications. This is also a good sample showing how to load (bootstrap) relational data from excel.
Add a timer without a schedule that will allow you to reset and reload the data. This can be useful if you want to use the data as test, make changes and then want to easily reset it.
