This thesis describes a notation for rapid specification of information visualization, which can be used as a theoretical framework of integrating various types of information visualization, and its applications at a conceptual level. The notation is devised to codify the major characteristics of data/visual structures in conventionally-used…

Information systems are becoming more than computer systems, with new equipment and techniques combining with data processing to form a new field called information technology. The emerging discipline of systems engineering is discussed along with nine systems engineering techniques. An organization chart of an information services department is…

In the development of library systems, the movement today is toward the so-called "total or integrated system. Although it may not be feasible in most cases to design and install a total system in a single operation, it is shown how a series of application programs can become the incremental development of such a system.

Proposes a microprocessor-based architecture that makes large use of parallelism both in processing and in retrieval operations. The proposed system consists of three functional blocks: the query processor, simple query executers, and the answer composer. Twenty-one references are listed. (FM)

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)

Discusses the multilevel information system (MLIS), a retrieval system that integrates functions typical for database management systems and retrieval-oriented systems and provides several levels of data accessing, each developed for a different class of users. Twenty-two sources are cited. (FM)

This document presents in schematic form a systems approach for the development of an executive information system. Although it does not use the traditional sentence and paragraph form, its diagrams, written in a sequence similar to computer programs, cover such topics as history of information systems, requirements analysis, how to begin building…

Systems analysis of an operating system consists of the evaluation of the efficiency, economy, accuracy, and productivity of existing procedures measured against the stated objectives of the library; and the design of new procedures to satisfy the demands of management and user. The data processing subsystem performs ongoing operations of function…

The development of information systems using an engineering approach that uses both traditional programing techniques and fourth generation software tools is described. Fourth generation applications tools are used to quickly develop a prototype system that is revised as the user clarifies requirements. (MLW)

This article describes present and future computer based systems used in counseling and guidance, and provides several descriptive references. The article describes five types of systems, some of which replace and go beyond certain current counseling functions. (Author)

Describes the development by Gould, Inc., S.E.L. Computer Systems Division, of an Information Management Package (IMP-32) for use in administration of the company's technical information center. Designing the system, the programs which are components of the system, and system functions are discussed. Included are eight figures illustrating system…

Problems of the college or university that center around the people who use the institution's computers are examined. It is suggested that effective use of computers in higher education depends on how well the users and providers understand the constraints and problems of each information system. (Author/SF)

Examines four working steps from an empirical model where an expert abstractor discovers what a paper is about and drafts a topic sentence; a simulation system is developed using this model. Discusses knowledge processing activities of professional summarizing. Results indicate that a small simulation model of professional summarizing is feasible.…

User perception of data importance and the economic feasibility of hardware and storage devices will determine the future direction of online systems. A retrieval system's functions are ultimately dictated by database design. Early online sytems were designed for bibliographic information limited to citations only using sequential files. When…

Part I is a discussion of the following project tasks: A) development of an on-line, real-time bibliographic data processing system; B) implementation in library operations; C) character sets; D) Project MARC; E) circulation; and F) processing operation studies. Part II is a brief discussion of efforts to work out cooperative library systems…
