  • 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 ...
  • 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 ...
  • MacGregor, K.J. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    The discipline of Computer Science has been established for almost twenty years. In SOUTH AFRICA, Computer Science Departments have been in existence for fifteen years, and producing graduates for twelve, however, the ...
  • Hirsch, Michael; Schach, Stephen R.; Van Biljon, Willem R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Two approaches to high-level debugging systems for Pascal are compared, namely the use of a debugging precompiler as against a debugging interpreter. A description is given of a high-level Pascal debugging interpreter ...
  • Philips, MJ; Berman, S (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 ...
  • Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Fourth generation languages offer substantial productivity benefits to data processing departments. Major problems associated with their use include the inability of conventional project management systems to control ...
  • Du Preez, L.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A bnef description of software conf1gurat1on management principles 1s given, followed by a d1scuss1on on the ap pl1cat1on of these principles in a spec1f1c installation
  • Postma, Stef W. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The paper is concerned with computer science as a science and the training required by its scientific practitioners-tobe. The background and objectives for a curriculum design are briefly sketched, and a taxonomy is given ...
  • Pirow, Peter (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    In five years of watching students operate terminals I have observed that the response time of the terminal has much to do with the comfort of the user. I have also observed this phenomenon in the business environment. ...
  • Pino, Jose A. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    This paper describes the design of MIGRATIONS, a software system under development at the University of Chile, whose purpose is to store, manage and retrieve unformatted text information. Among the most important design ...
  • McDermott, T.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A language-independent syntax-directed editor for teaching programming languages on micro-computers is briefly described. The design of the configuring grammar and the lnternal tree-structure to be edited and interpreted ...
  • Labuschagne, W.A.; Van Rooyen, H.O. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A technique for partially representing binary group operations by sets of binary relations was devised by Cayley. This technique can be generalised to permit the representation of arbitrary sets of n-ary relations {n ~ ...
  • Du Preez, L.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A brief description of software configuration management principles is given, followed by a discussion on the application of these principles in a specific installation.
  • 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 ...
