ABSTRACT
Extensible Markup Language (XML) has been widely used as the standard representation for data sharing and interchange between global enterprises. Numerous organisations have started to develop XML-based standard (in the form of XML Schema) for data exchange within their domains. For example, XML standard for health data exchange (HL7), financial data exchange (FIX), aviation data exchange (AIXM), etc. It is important for the industries to adopt this new standard to allow them to interact with one another in this global enterprise era. However, the challenge behind the issue of adopting XML standard for a company that already has an existing database system is how to detect and resolve conflicts caused by the different modelling of real world entities, different data models or different representations of the same object. In this paper, a comprehensive taxonomy of all possible conflicts in adopting XML standard is discussed. Based on this taxonomy, a suitable method for detecting conflicts along with a detection flow and algorithms are examined and implemented. In addition, an extensive evaluation based on a real global aviation database is employed to examine the quality of the proposed methodology.
