Summarizes the first phase of a federally funded study of 157 clearinghouses that store data on human services. Factors addressed include the tasks of a clearinghouse, its potential for overlap, its relationship to its parent organization, the types of product and services it provides, and how it uses its database.

Develops an approach for advance estimation of user charges based on information actually retrieved by searching numeric databases, and defines a method for query cardinality estimation. Based on the relational data model, which uses relational algebra, this method uses formal file descriptions to describe the database files. (LRW)

A segment of a longitudinal study of the changing management philosophy of a public school organization involves the introduction of a new technology--the use of an integrated information system--in an environment that was to have been prepared for change. The administrators and staff of the organization had participated in a feasibility study…

A more complete definition of the features offered in present day generalized data base management systems is provided by this second technical report of the CODASYL Systems Committee. In a tutorial format, each feature description is followed by either narrative information covering ten systems or by a table for all systems. The ten systems…

The URBANDOC General Manual is the second volume of the final report of the URBANDOC Demonstration Project. All three volumes are concerned with the applicability of computerized documentation techniques to the literature of urban planning and renewal. The "General Manual" stands midway between the "Demonstration Report" (see…

Describes experiment designed to assess information value for individual searchers in realistic search environment. Included in data analysis are comparison of two alternative retrieval methods, evaluation of how well humans are able to estimate document relevance, and investigation of value function components (features and coefficients) and…

The findings of a CAUSE survey of institutions of higher education that are either currently using or have used a database management system are presented. In addition to demographic information, other issues addressed are: management implications, systems concepts, systems development, personnel, operational considerations and prospects for the…

The proceedings of this conference, which examined the relationship between mathematical programming and the computer, contains the texts of most of the 50 papers presented and a summary of one discussion panel addressing such facets of this theme as the design for, use of, implementation of, and implications for mathematical programming software…

This report provides a complete guide to the stand alone mode operation of the reliability and maintenance (R&M) model, which was developed to facilitate the performance of design versus cost trade-offs within the digital avionics information system (DAIS) acquisition process. The features and structure of the model, its input data…

The 266 items cited include material published since July 1960, organized in the following ten groups: (1) general discussion, and feasibility; (2) statewide electronic data processing (EDP) systems; (3) EDP in local governments; (4) intergovernmental EDP systems; (5) EDP in the planning agency; (6) data banks and information systems; (7) computer…

This monograph, based on a conceptual model called an information support circle, describes a structured management process that can be used by higher education institutions to add value to institutional data and information. The model offers a sequence of (1) thinking about the management and use of data, (2) considering problems in providing…
