    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 ...
  • Tidwell, LD; Schach, Stephen R. (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 ...
  • Smith, DC; Hansen, AL; Oosthuizen, NC (South African Institute of Computer Scientists and Information Technologists, 1991)
    Staff Shortages in the Information Systems industry are a continuing problem. Job turnover of IS staff contributes to this shortage and is particularly high in South Africa. This high turnover is often attributed to ...
  • Philips, M.J.; Berman, Sonia (South African Institute of Computer Scientists and Information Technologists, 1991)
    The universal relation is a way of overcoming users' prime database access difficulty, namely navigation through database structures. As a result there is reduced user involvement with the underlying logical database ...
  • Finnie, G.R. (South African Institute of Computer Scientists and Information Technologists, 1991)
    Forecasting techniques are used extensively in a variety of business (and other) applications for the analysis and prediction of various factors of interest e.g. future market demand for a specific product. However, the ...
  • Erlank, S; Pelteret, D; Meskin, M (South African Institute of Computer Scientists and Information Technologists, 1991)
    The systems development process is commonly described in terms of a System Development Life Cycle (SDLC). There is a wide range of tools and techniques available to the system developer, and these are typically used for ...
  • Cloete, I; Theron, H (South African Institute of Computer Scientists and Information Technologists, 1991)
    Quinlan's ID3 is a popular and efficient algorithm for inducing decision trees from concept examples, where the examples are presented as vectors of attribute-value pairs. If some attributes have integer or real domains ...
  • Clayton, Peter G. (South African Institute of Computer Scientists and Information Technologists, 1991)
    This paper introduces a class of concurrent programming construct based on an interrupt driven paradigm. This programming model is designed to simplify the application of conventional imperative programming techniques ...
  • Bosua, R; Du Plessis, A.L (South African Institute of Computer Scientists and Information Technologists, 1991)
    Specification languages to be used in conjunction with Ada as the implementation language have been proposed in the literature. Simultaneously, methods for the development of real-time software systems have been introduced, ...
  • Barrow, J (South African Institute of Computer Scientists and Information Technologists, 1991)
    Hypertext is presented as a database accessing mechanism well-suited to computer aided learning applications. On the basis of informal experiments with prototype software, some benefits of structured hypertext are explored. ...
