A tutorial introduction to data models in general is provided, with particular emphasis on the relational and network models defined by the two proposed ANSI (American National Standards Institute) database language standards. Examples based on the network and relational models include specific syntax and semantics, while examples from the other…

Findings and recommendations from a study conducted to define the college's information needs, and to diagnose and assess the administrative data processing operations. (Author/MLF)

A statistical model for characterizing the growth patterns of data base utilization and for estimating future utilization levels of demand has been developed for information retrieval organizations. Illustrations of the model applied to a typical information retrieval organization are given and discussed. (5 references) (Author)

Describes the meaning of the term multimedia database and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined. Seventeen references are listed. (Author/LLS)

Discusses how imprecision and uncertainty are dealt with in the UFO (Uncertainty and Fuzziness in an Object-oriented) database model. Such information is expressed by means of possibility distributions, and modeled by means of the proposed concept of "role objects." The role objects model uncertain, tentative information about objects,…

Survey results from 183 middle and high schools in Tennessee and 20 business education coordinators were used to build a profile of business education programs in the state. The data prototype can be used by state departments of education to determine the status of business education programs. (Author/JOW)

The 5-Factor Wel, the latest version of the Wellness Evaluation of Lifestyle (WEL), was examined using a completely new 3.993-person database. Through exploratory and confirmatory factor analysis with 2 discrete subsets of these data, a new 4-factor solution was identified that provided the best fit for the data and accounted for 30% of the…

There are described methods used to minimize data files dimension. There are defined indicators for measuring size of files and databases. The storage optimization process is based on selecting from a multitude of data storage models the one that satisfies the propose problem objective, maximization or minimization of the optimum criterion that is…

This study describes one of possible way of usage ICT in education system. We basically treated educational system like Business Company and develop appropriate model for clustering of student population. Modern educational systems are forced to extract the most necessary and purposeful information from a large amount of available data. Clustering…

A hypothetical model is given for a National Serials Data System based on the best educated guesses of what the system should do and how, therefore, it should function. The model focuses attention on the ultimate goal rather than on the decision-making processes relating to choice of data elements, unique identification codes, etc. This conceptual…

Discussion of factors that influence a publisher's choice of electronic and media delivery techniques; assesses use of diskettes, Bernoulli removable cartridge disks, CD-ROM, modems using dial-up phone lines, leased phone lines, satellites, and FM subcarriers. Sample data sizings are evaluated, and a cost model of electronic delivery costs is…

Discusses the problems associated with using connect time as the basis of user fees for searching numeric online databases, and proposes a methodology for user charge estimation based on query formulation and results. (87 references) (CLB)

The benefits of prototyping as a basis for system design include better specifications, earlier discovery of omissions and extensions, and the likelihood of salvaging much of the effort expended on the prototype. Risks and methods of prototyping during rapid systems development are also noted. (Author/MLW)

This paper discusses the first major implementation of two significant new cataloging models: IFLA's FRBR (International Federation of Library Associations' Functional Requirements for Bibliographic Records) and event modeling (INDECS and Harmony). The paper refers briefly to the decision making processes leading to the adoption of these models,…

The assessment responses in the following articles by Charles H. Buzzell, David V. Tiedman and Jacob J. Kaufman are offered to provide the reader with reference points for determining the usefulness of MISOE. Each assessor responded from a professional perspective. (Editor)
