  • A program development environment for microcomputers 
    Byron-Moore, S.P. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Any distractions in the working environment can affect the quality and quantity of output. For example, noise may disturb a person's thought processes and lead to errors. In addition, the programmer is subject to other, ...
  • The ELSIM language: an FSM-based language for the ELSIM SEE 
    Du Plessis, A.L.; Bornman, C.H. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A fonnal requirements specification language, the ELSIM language, is presented. The language uses conceptual models for modelling data processing, and control characteristics and behavior of real-time systems, and is ...
  • Common approach to some informational systems 
    Orlowska, M.E. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    In this paper we consider relationships between a complete system [6], an L-system [3], a stochastic system [13] and an N-system [8]. We introduce a notion of the induction of one system by another. We prove the important ...
  • Strategic planning models for information systems 
    Bruwer, P.J.S. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A key to the success of the information system function in organizations is a comprehensive, effective planning system. According to R.V. Head's[l] pyramid structure of an Information system managers are classified into ...
  • Pointers as a data type 
    Philips, N.C.K.; Postma, Stef W. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The distinction between an abstract data type and an implementation of a data type is not as clear as is commonly thought. A hash table can be used to implement the type bag but few of our colleagues think of a hash table ...
  • A comparison of academic and practitioner perceptions of the changing role of the systems analyst: an empirical study 
    Crossman, T.D. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Changes in technology introduce new job responsibilities and demand new skills profiles from personnel involved in application software development. Inability to perfonn competently within these job responsibilities can ...
  • Abstracts of Old mutual conference for Ph.D and M.Sc students In Computer Science, Stellenbosch, 2-3 October 1987 
    Unknown author (Computer Society of South Africa (on behalf of SAICSIT), 1987)
  • A model to evaluate the success of information centres in organizations 
    Bruwer, P.J.S.; Groenewald, J.J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The objective of this research report was to investigate some South African organizations who have been operating information centres (IC's) successfully for more than two years. As the success of the IC is strongly · ...
  • Three packaging rules for information system design 
    Mende, J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    After identifying the processing functions required in a computer based information system, the designer needs to combine them into an optimal set of load units. Some "packaging" arrangements yield a better system ...
  • Generating relations using formal grammars 
    von Solms, S. H. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Grammars generating 2-dimensional arrays have been studied by many people [1, 2, 3, 4). One effort was Random Context Array Grammars [4], where different types of context conditions placed on the production, were used ...
