Get books with lab materials. Element K has some great stuff, and Axzo press has good supporting materials, and publishes previews of their books online. Email either one of these publishers, tell them you are considering using their materials for in-house training. They'll send you an evaluation copy for free. The stuff we use in our classes works because after spacing out to what I say for an hour, the participants then have to build it using supporting activities. Reference books, or even college texts don't typically include that. Grab a lab manual on MS Access and skip all the access-specific stuff. Every training guide starts with the fundamentals of DB structure and normalization.

I never had a good understanding of normalization until I had to build reports. Only when you run into brick walls imposed by your data, do you really see the value.

We use NComputing for a number of clients, both large and small. Not just the large enterprises that everyone keeps talking about in this thread. They are very economical, provide a usb port for the local user, and we only have to maintain one pc. We can recycle old monitors and keyboards, and one good dell optiplex running winXP can run a lot of 10 of them. You have to pay careful attention to windows updates - there have been a few that will break ncomputing. But other than that, it's pretty worry-free.
