HyperCard was everywhere on the Mac in the late 1980s. It was so much more accessible than most anything comparable on the PC. Its short life was due to other better database choices coming out — such as FileMaker or 4D — and, of course, the advent of the World Wide Web, which was, at that time, a collection of HTML pages and CGI scripts often written in perl.
Speaking of, its creator Bill Atkinson famously said that his big mistake with HyperCard was to not have cards connect to one another through a network. Imagine what that could have been!
