Abstract:
Data integration is essential for building modern enterprise information systems. This paper investigates the implementation of XML data integration through transforming XML data from different data sources into a common global schema. Following the work our research group has done earlier, the paper is focused on the implementation of XML data transformation. First, the proposed methodology to realize XML data integration is sketched. Then, the representation of a DTD and document and other relevant concepts for transforming XML data are presented. The transforming operations defined by a set of operators are outlined focusing on the required functionality for data integration. Building upon these, the implementation of the data transformation operations is investigated. The current implementation is reported with a simplified example illustrating how the methodology can be applied for practical enterprise information integration.
