Can anyone recommend a decent database program for me that is easy to understand for someone not too good with computers? A friend of mine is running a small business which has developed a somewhat large customer base, and now requires a sensible way of catalouging this information. He's looked at some software that others has recommended such as the open source Vtiger, but he can't get his head around them. I have no experience with these programs myself so have no idea what to recommend. Anyone?
