This handbook is more than a standard introduction to databases; it is a comprehensive set of tools that makes learning basic database and hypermedia concepts much easier. The basic ideas and architecture of relational and object-oriented databases are presented, followed by hypermedia systems, hypermedia and the Internet, second generation hypermedia, and hypermedia data models. The material is presented in both printed form with many illustrations and in the form of 26 interactive electronic lessons for Windows.
