  • Keeping research data safe 

    Stanger, Nigel
    Most researchers will create or acquire numerous sets of data during their career, but the sad reality is that many of these data sets are not managed systematically. This was not such an issue when data sets were relatively ...
  • Evaluating the impact of the School of Business digital repository 

    Sanmaneechai, Charupol
    Otago EPrints is an open access institutional repository at the School of Business, University of Otago. Authors within the school can deposit their work such as journal articles, working/discussion papers, conference ...
  • A lightweight data integration architecture 

    Williamson, David W
    Content syndication specifications such as Atom have become a popular mechanism to disseminate information across the Internet, with many sites providing Atom feeds for users to subscribe to and consume. Such a scenario ...
  • EPrints makes its mark 

    Stanger, Nigel; McGregor, Graham
    Purpose — To report on the impact and cost/benefit of implementing three EPrints digital repositories at the University of Otago, and to encourage others to follow suit. Design/methodology/approach — Three repositories ...
  • Translating between SQL and Tutorial D 

    Almulla, Ahmed Yusuf
    The relational model of data has a strong influence on the database field and cannot be discarded for any future direction regarding the development of databases (Date and Darwen, 2007). Two relational database languages ...
  • Exploiting the advantages of object-oriented programming in the implementation of a database design environment 

    Stanger, Nigel; Pascoe, Richard
    In this paper, we describe the implementation of a database design environment (Swift) that incorporates several novel features: Swift’s data modelling approach is derived from viewpoint-oriented methods; Swift is implemented ...
  • A viewpoint-based framework for discussing the use of multiple modelling representations 

    Stanger, Nigel
    When modelling a real-world phenomenon, it can often be useful to have multiple descriptions of the phenomenon, each expressed using a different modelling approach or representation. Different representations such as ...
  • Modifications to Smith’s method for deriving normalised relations from a functional dependency diagram 

    Stanger, Nigel
    Smith’s method is a formal technique for deriving a set of normalised relations from a functional dependency diagram (FDD). Smith’s original rules for deriving these relations are incomplete, as they do not fully address ...
  • A graphical notation for physical database modelling 

    Pillay, Antonia; Stanger, Nigel
    In this paper we describe a graphical notation for physical database modelling. This notation provides database administrators with a means to model the physical structure of new and existing databases, thus enabling them ...
  • Translating descriptions of a viewpoint among different representations 

    Stanger, Nigel
    An important part of the systems development process is building models of real-world phenomena. These phenomena are described by many different kinds of information, and this diversity has resulted in a wide variety of ...
  • A lightweight data integration architecture using Atom 

    Williamson, David W; Stanger, Nigel
    Cost is a major obstacle to the adoption of large-scale data integration solutions by small to medium enterprises (SME’s). We therefore propose a lightweight data integration architecture built around the Atom XML syndication ...
  • Environments for viewpoint representations 

    Stanger, Nigel; Pascoe, Richard
    Modelling the structure of data is an important part of any system analysis project. One problem that can arise is that there may be many differing viewpoints among the various groups that are involved in a project. Each ...
  • The digitisation of New Zealand’s research, heritage and culture 

    Stanger, Nigel
    Over the last 25 years, it has become possible to digitise and store an ever-increasing amount and variety of material. New Zealand has been one of the leaders in this area, with early initiatives such as the New Zealand ...
  • Scalability of techniques for online geographic visualization of Web site hits 

    Stanger, Nigel
    Extremely large data sets are now commonplace, and they are often visualized through the World Wide Web. Scalability of web-based visualization techniques is thus a key issue. This paper investigates the scalability of ...
