In this paper, the author reports the results of an empirical study on the relationship between a student's programming experience and their success in a traditional Systems Analysis and Design (SA&D) class where technical skills such as dataflow analysis and entity relationship data modeling are covered. While it is possible to teach these…

The constructive phases of system design are discussed with particular reference to information systems design. A preliminary attempt is made at definition of terms and an initial organization of research presented. A synopsis of work to date is presented within the framework of three thrust areas (1) creative and intuitive design methods, (2)…

It is recognized that there is a major gap between the promises of large data bases and optimization and simulation models and their actual ability to solve real world problems. This document describes a Generalized Data Base Planning System (GPLAN), currently being developed at Purdue University, that is proposed as a system to bridge this gap. A…

Overview of expert systems (intelligent computer applications that use data, a knowledge base, and a control mechanism to solve problems) highlights history of expert systems; construction (human element, knowledge acquisition and learning, system architecture); limitations; issues and trends; and implications for information science. Thirty-three…

Unified organizational systems with integrated information systems are required to deliver effective referral and remedial services to children who are experiencing learning problems. However, such organized systems do not exist widely enough in our schools. The purpose of the project was to develop a consensually derived data-referral system for…

The most time consuming and expensive step in developing expert systems is knowledge acquisition (KA), and it is important to determine how the limited resources for acquiring knowledge should be allocated across different sources. This paper develops a model that determines how KA resources should be spent and how such a model may be used. (23…

Describes the design and development of a case-based reasoning (CBR) knowledge repository, including its case library and the search engine to support the technology integration community. The process and results of ormative evaluation following the concept of participatory design are reported to set the context for further research and…
