  • 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 ...
  • Efficient evaluation of regular path programs 
    Wood, PT (South African Institute of Computer Scientists and Information Technologists, 1992)
    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 ...
  • Finding regular paths in acyclic graphs 
    Wood, PT (South African Institute of Computer Scientists and Information Technologists, 1990)
    Increasing the expressive power of relational query languages by providing some form of recursion is currently a topic of much research. For many recursive queries in relational databases, a relation can be represented ...
  • HILOG - a higher order logic programming language 
    Paterson-Jones, RA; Wood, PT (South African Computer Society (SAICSIT), 1992)
    HILOG is a new logic programming language with a higher-order syntax allowing the elegant expression of many tasks requiring meta-predicates in Prolog. We are in the process of developing a compiler and programming environment ...
  • A model for object-oriented databases 
    Brand, M; Wood, PT (South African Computer Society (SAICSIT), 1992)
    Unlike the relational model, there is no universally accepted object-oriented data model. This has led to systems being defined in an ad-hoc manner, with the resultant difficulty of determining exactly what features are ...
