    De Villiers, C; Roode, JD (1995)
    lnterpersonal skills and communications are the two topics in Curriculum '95, compiled by the joint task force of the ACM/AIS-ICIS/DPMA, where both academics and industry expect the level of knowledge of the students to ...
  • An object-oriented strategy for banking 
    Daratos, J; Steenkamp, AL (1995)
    Many information strategists today agree that the Object-Oriented Technology (OOT) has particular requirements that should not be omitted from a traditional Information Technology (IT) strategy. An Object-Oriented Strategy ...
  • A structured approach to integrate heterogeneous case tools 
    Bosua, R (1995)
    Multiple CASE tools that support systems analysis and design are available today. These tools are becoming indispensable in its support for the systems development process, although the support varies in term of the methods ...
  • The application of scripts to deadlock avoidance 
    Blewett, CN; Erwin, GJ (1995)
    We describe the prototype of an expert system software advisor for the lock manager of a database system. The software advisor, called EAGLE (Expert Advisor for Granting Locks Effectively), is intended to become an ...
  • Research on Mobile Cloud Computing in Teaching and Learning: A Conceptual Model 
    Van Biljon, Judy; Van der Merwe, Ronell (Academic Conferences and Publishing International Limited, 2018)
    Advances in cloud computing technology coupled with increasing volumes of data has driven the growth and differentiation of cloud-based solutions in teaching and learning. The cloud computing industry has matured over the ...
  • Citizen Science: The Ring to Rule Them All? 
    Van Biljon, Judy; Van der Merwe, Ronell (Academic Conferences and Publishing International Limited, 2018)
    There are many uncertainties about the future of e-Learning, but one thing is certain: e-Learning will be more data-driven in the future. The automation of data capturing, analysis and presentation, together with economic ...
  • Business computing: an African perspective 
    Blewett, CN; Erwin, GJ (1995)
    The book uses storytelling as teaching, with exclusive use of active tense, local examples a problem-driven approach rather than a product-driven approach. For example, magnetic tape principles are explained in ...
  • Loss probabilities for circuit-switched networks 
    Berezner, SA; Krzesinski, AE (1995)
    Consider a circuit-switched network where several source switches are connected to a destination switch via a tandem switch. Circuit-switched networks traditionally employ a Blocked Calls Cleared ( BCC) admission rule: a ...
  • A writing support tool for distance students 
    Barrow, J (1995)
    This paper describes SuperText, a computer program designed to support productive expository writing processes among students at a distance teaching university. Being able to write well is an import communication skill, ...
  • Efficient evaluation of regular path programs 
    Wood, PT (1991)
    The next generation of query languages for database systems should have the ability to express recursive queries, the efficient evaluation of which will be crucial to the success of these systems. One such query language ...
  • A transputer-based embedded controller development system 
    Webster, MR; Harley, RG; Levy, DC; Woodward, DR (1991)
    This paper describes a software development environment currently being built at the University of Natal that provides a powerful and easy to use engineering tool for the design, simulation and implementation of high ...
  • The design of a speech synthesis system for Afrikaans 
    Wagener, MJ (1991)
    The design of a speech synthesis system for the generation of speech from text is presented. The system accepts any Afrikaans sentence and then derives segmental and suprasegmental informa­tion through various linguistic ...
  • A model checker for transition systems 
    De Villiers, PJA (1991)
    A model checker automatically determines whether a model of a re­active system satisfies its specification.Temporal logic is used to spec­ify the intended behaviour of a reactive system which is modelled as a transition ...
  • Extending local recovery techniques for distributed databases 
    Viktor, HL; Rennhackkamp, MH (1991)
    The most frequently used local database system failure recovery techniques are logging, shadowing and differential files. In a distributed database these, local system failure recovery techniques may be utilized for recovery ...
  • A value can belong to many types 
    Venter, BH (1991)
    Most statically typed Algol-style languages were designed to conform with the view that a value belongs to one and only one type. The adoption of this view bought compiler simplicity at the ex­pense of language expressivity. ...
  • Using statecharts to design and specify a direct-manipulation user interface 
    Van Zijl, L; Mitton, D (1991)
    Statecharts were developed by Harel et al [10] to specify complex reactive systems. In this paper we report on our application of statecharts as a design and specification tool for an X-Windows based Graphical User ...
  • Object orientation in relational databases 
    Rennhackkamp, M (1991)
    There is, as yet, no single formal definition for the object-oriented approach. The object-oriented paradigm is described in terms of the concepts accentuated by the approach, namely classes, objects, methods, messages and ...
  • Integrating similarity-based and explanation-based learning 
    Oosthuizen, GD; Avenant, C (1991)
    Recently, there have been various attempts to combine the strengths of similarity-based learning (SBL) and explanation-based learning (EBL) in a single learning system. We describe a graph-based learning method called ...
  • Building a secure database using self-protecting objects 
    Olivier, MS; Von Solms, SH (1991)
    In current database systems the responsibility for enforcing security is often given to the various application programs. Even where the Database Management System (DBMS) does supply security mechanisms, a single application ...
  • Analysing routing strategies in sporadic networks 
    Melville, S (1991)
    CommunIcations networks with sporadically available links pose particular problems in terms of delay analysis. This paper presents an approach to determining the effectiveness of various routing strategies when applied ...
