    Design and Usage of an IT-System for workplace management with ergonomic analysis under health protection aspects
    (Enterprise modelling and information systems architectures – concepts and applications, 2007) Dubian, Clemens; May, Wolfgang
    This article describes an information system for analysis and description of workplaces under the aspects of health protection and ergonomic risks, which is currently being developed at Volkswagenwerk Kassel. The system provides an instrument for matching ergonomic risks of workplaces with work limitations of employees for an efficient assignment of employees to appropriate workplaces. It integrates data from several existing systems and collects additional data. The collection and maintenance of data is accomplished by an analysis team and by the team leaders in the factory. Besides the functional aspects, the following two issues have been solved: minimizing the effort for the collection and maintenance of data by using a hierarchical categorization of the objects of interest and their properties. Secondly, for accomplishing the acceptance and direct benefit for the following user groups (health care, human resource management, and most of all, local supervisors), group-specific graphical user interfaces are provided.

    A logical, transparent model for querying linked SML documents (Kurzbeitrag)
    (BTW 2003 – Datenbanksysteme für Business, Technologie und Web, Tagungsband der 10. BTW Konferenz, 2003) May, Wolfgang; Malheiro, Dimitrio
    The W3C XML Linking Language (XLink) provides a powerful means for interlinking XML documents all over the world. While the effects when browsing through linked XML documents are well-defined, there is not yet any proposal how to handle interlinked XML documents that make use of the XLink language from the database point of view, i.e., considering the data model and navigation/querying aspects. From the database (and in general, querying) point of view, elements with linking semantics can be seen as virtual XML subtrees, i.e., XML views. Compared with classical databases, i.e., SQL and relational data, the situation of having links inside the data is new. We define a logical, transparent data model for linked documents. Queries are then formulated in standard XPath against the logical model. We propose additional attributes using the dbxlink (database-xlink) namespace for specifying the mapping from XLinks to the logical model.
