  • Remenyi, DSJ (South African Computer Society (SAICSIT), 1993)
    This paper takes a business or commercial perspective of the key issues in Information Management for the mid-1990s. It focuses on how organisations may use information systems to improve their efficiency and effectiveness ...
  • Ram, V (South African Computer Society (SAICSIT), 1993)
    The use of Expert Systems technology in management decision making domains is increasing rapidly as business environments worldwide grow more turbulent and as the cost of development tools decrease. Research effort in this ...
  • Parker-Nance, TC; Warren, PR (South African Computer Society (SAICSIT), 1993)
    Usability problems with computer systems can be divided into three broad categories: problems due to the socio/political environment, problems due to the usefulness of systems, and problems due to the accessibility of ...
  • Norman, MJ; Berman, S (South African Computer Society (SAICSIT), 1993)
    Software Engineering is a difficult and time-consuming discipline to learn. CASE Tools are generally expensive, prescriptive and tedious to use. Structured Software Development Environment (SSDE) was developed as a teaching ...
  • Mullany, M; Dos Santos Gomes, A; Miller, R (South African Computer Society (SAICSIT), 1993)
    After reference to IS authors such as Lay [7J it becomes evident that there is as yet no unified definition of the term "information system." This research has attempted to extract, from the relevant literature, the supposed ...
  • Lamprecht, SM (South African Computer Society (SAICSIT), 1993)
    Distributed database systems provide users with the facility to utilize and maintain information that is geographically dispersed in files at several sites while they remain unaware of the distribution of the information. ...
  • Jordaan, DB; Hattingh, JM; Steyn, T (South African Computer Society (SAICSIT), 1993)
    Daar bestaan baie voorbeelde in die dataverwerkingswêreld van gebruikers wat nie die inligting vanuit huIlle rekenaarstelsels kry wat hulle nodig het nie [26]. Nuwe en onvoorsiene vrae en versoeke vir inligting neem by die ...
  • De Kock, G de V; Du Plessis, C (South African Computer Society (SAICSIT), 1993)
    An evaluation is made of the success of equivalence algorithms to be used for surname matching in a South African Genealogical Database. Surnames in the database can be grouped in ideal equivalence classes. The algorithms, ...
  • Crossman, TD (South African Computer Society (SAICSIT), 1993)
    Some sources suggest that the implementation of Artificial Intelligence and Expert Systems applications (AI/ES) may create problems for the business sector. This article presents a management tool (based on the concept of ...
  • Viktor, HL; Rennhackkamp, MH (South African Institute of Computer Scientists and Information Technologists, 1991)
    A recovery technique, to facilitate the recovery from system failures should ensure a consistent database state at all times. The UNIX write system call uses a delayed-write policy. Data blocks are kept in a buffer cache ...
  • Sutcliffe, Geoff (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    In general graph theorists have a limited knowledge of computers and computing, and are unaware of the possible variations of representation available, and in what circumstances which representation would be better. To ...
  • Tidwell, LD; Schach, SR (South African Institute of Computer Scientists and Information Technologists, 1991)
    It is becoming increasingly difficult for researchers with little or no formal computer science background to make effective use of supercomputers and other vector machines in their own fields of research. Automatic ...
  • Short, R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Formalisms comprise the essential bricks and mortar that we need in order to construct information systems. Not surprisingly therefore the invention and refinement of formalisms has formed and continues to form a ...
  • Machanick, Philip (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    After a brief look at how the notion of the stored program is applied by programmers in the area of Artificial Intelligence (Al), we shall look at a specific Al tool: a production svstem. The discussion is at a ...
  • Turton, Trevor (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    This paper describes computer design which 'would achieve a high instruction throughput rate on a relatively modest amount of hardware. It is based on multiprogramming the CPU at a sub-instruction level. The design will ...
  • Richfield, J.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Structured program design is urged as a rewarding vehicle for the introduction of computer concepts to age groups ranging from mid primary school to senior management. Progressively expanded subsets of the material form ...
  • Mueller, C.S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Why concurrency in itself should be seen as a method of programming, is discussed. Current approaches to concurrent programming are evaluated in terms of e~e qt programming. The properties required to decompose the ...
  • Kaplan, S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The notion of and mot1vat1on for intelligent editor systems 1s introduced, spec1f1cally a language independent intelligent editor called "PASTOR" We also introduce and discuss the metalanguage used in the editor for grammar ...
  • Hunter, D.A. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The South African Data Centre for Oceanography (SADCO) has implemented a multi d1sc1plinary oceanographic database using OMS 170, a relational database management system Using a high level query language sc1ent1sts from ...
  • Jablonski, J.; Dijkman, J.H. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The design of a high speed graphics workstation 1s presented A spec1f1caly designed Graphics System Interface com bines standard computer peripherals to produce a soph1st1cated man machine workstation A review 1s given ...
