An approach to data description and conversion

Abstract: : Currently, the structure of stored data is determined implicitly by the software which accesses and processes it. This data structuring technology has given rise to two outstanding problems in data processing. First, there is the communication of the exact structure of data to users and machines, and secondly, the interchange of the data itself. This work contributes to overcoming these problems by developing a technique for describing the structure of data explicitly and independently of machines and software. This aim is to understand data structures by developing a model which not only characterizes current data organizational techniques, but also provides a framework within which new data structures can be defined, to use this model to develop a language which can explicitly describe the organizatin of data, and to use this model to study how data can be converted from one structure to another, with a view towards developing a method for describing data conversions.

TRACE—III: An implicit programming system for inductive data analysis

Abstract: A previous on-line data analysis system has been generalized and extended on a Digital Equipment PDP-10 computer into an implicit programming system utilizing a special-purpose programming language aimed at behavioral scientists with little or no data processing background who desire to perform special-purpose data analyses or examine their data from an inductive as well as a deductive stance Central to this new system is a comprehensive data management subsystem that retrieves data from a data base according to implicit associations among data units; that updates the data base with the results of data manipulations in a way that preserves associations among existing data units and establishes such associations with new data units; and that relieves the user of all responsibility for database and file management
