Any other SQL or MS Access / OleDb databases available?

[BobLewiston]

I'm working through the lessons at Programmer’s Heaven's "C# School" tutorial (http://www.programmersheaven.com/2/Les_CSharp_0), and I'm currently on lesson 13, "Data Access in .Net using ADO.Net", so of course I've been trying to connect to Programmer’s Heaven's SQL and MS Access / OleDb databases. Unfortunately, they're now offline. Can anyone please tell me; are there other such databases available for those learning ADO to practice connecting to?

Microsoft provides a "Northwind" database for testing. They have ms sql versions and Access versions (that I am aware of) and usually come with the associated product.
