Students, families, colleges, and lawmakers need clearer information on postsecondary outcomes to make informed decisions. By leveraging data available at institutions and federal agencies, a nationwide student-level data network (SLDN) would close information gaps that persist in our higher education landscape to answer critical questions about…

Data compression is the art of using encoding techniques to represent data symbols using less storage space compared to the original data representation. The encoding process builds a relationship between the entropy of the data and the certainty of the system. The theoretical limits of this relationship are defined by the theory of entropy in…

A record format and file structure for searching and editing of large textual files have been designed within the 3RIP project. This document describes: (1) general characteristics of the system; (2) implementation of the system on a DEC 10 computer in the programming language, BLISS; (3) external record format; (4) internal format; and (5) file…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…

Examines the structure and components of information storage and retrieval systems and information filtering systems. Identifies 13 components as representations of data objects (copies, excerpts, descriptions, abstractions, and identifying references) and functions that operate on them. Reduces the functional components to transformation and…

The nature of typical mechanized data bases with which university information centers and libraries will be working is examined to provide background information for data base retrieval efforts. Format and content of the data must be taken into consideration before meaningful retrieval can be achieved. Hence both of these aspects are treated in…

Concern is growing over the problems of freedom of information, individual right to privacy, and automated recordkeeping systems. As a guide to policy considerations for overview and for detail, this extensive structured bibliography of privacy and disclosure literature adopts a topical scheme, dividing the subject first into governmental and…

An international numerical coding structure is presented for classification of data on education according to level category, educational field, and program type. Explanation of the overall system and a guide for its use is followed by a listing of levels, fields, and programs of education in coded order. The various educational program…
