Integrating a network-structured database into an object-oriented programming language
Ira Goldstein · 1980
Smalltalk is an object-oriented language (Ingalls78, KayGoldberg77, Hewitt73). PIE is a subsystem that extends Smalltalk's descriptive power by supporting the creation, storage, retrieval and manipulation of network structures (GoldsteinBobrow80a,b,c; BobrowGoldstein80). These networks have been employed to represent software, documentation, electronic mail, calendars, people, addresses, bibliographic references and other items that together comprise the personal information space of a user of an office information system. By employing a common network representation, PIE supports an integrated environment for software development and office-related tasks. PIE has been developed collaboratively with Dan Bobrow, and is presently being used on an experimental basis by a small community at Xerox PARC.
