Re: I guess the truth hurts.
There used to be simple database programmes in the 80s and 90s that came on the front of computer magazines, or could be bought for a few quid. These did pretty much all that an ordinary office worker or business owner in a small company would need to store and sort simple information, like the details of a few hundred customers. Something like; Company Name>>Address>>Phone number>>Contact name>> main area of business>>Purchases. With just enough data management tools to be able to, say, sort out which customers were in the local postcode area, or which ones had previously bought a Mk 3 widget polisher. And even which customers in a given postcode area had already bought a Mk 3 widget polisher!
Relational databases take far too much time and complexity to even learn how to use, or to set up. And no small business can afford to buy in an expert to create something far too big and clunky for their needs, if it can be made to work at all. So of course they use Excel. Can't blame them either.
