Capturing chemical information in an extended relational database system

This paper proposes extensions to the relational database model to allow chemical structure and other complex data types to be included in a relational database. It is argued that this approach provides benefits over the common practice of storing chemical structures in a chemical database system and associated research data in a relational or other general database system. The design and implementation of an extended relational system in the context of the Upjohn Cousin compound information system is discussed. User experiences are described and new opportunities in extensible database systems are reviewed.

Manufacturing productivity education data control by a general database system

This paper describes a database system which is in use by a National Science Foundation funded education project. The major thrust of the project is to develop and distribute modularized learning units which are concerned with topics in manufacturing productivity. The database, which utilizes the FORTRAN-based GPLAN/DMS 3 system, stores and controls the selective input and output of data concerned with manufacturing productivity education. The database logic and structure are described and examples of input and outout are presented.
