HyperCard

HyperCard is an application program for Apple Computer, Inc. that was among the first successful hypermedia systems before the World Wide Web. It combines database capabilities with a graphical, flexible, user-modifiable interface. HyperCard also features HyperTalk, a programming language for manipulating data and the user interface.

This combination of features - simple form layout, database capabilities and ease of programming - led to widespread use in many different roles. Some HyperCard users employed it as a programming system for Rapid Application Development of applications and databases, others for building interactive applications with no database requirements, command and control systems, and many examples in the demoscene.
