This one time, I had a job. While there the boss asked if I could create something to speed up their internal order system which at the time was all written by hand, using a pen and paper.With a little knowledge of Microsoft Access I created a simple form and printable report. It worked.

Then he asked if I could link it somehow to their current customer database, to save writing out the customer name and address. I couldn't do that, but I could create a customer database in Access and import their old data into that.
