Converting XML Data to UML Diagrams for
Conceptual Data Integration (Abstract)
The demand for data integration is rapidly becoming larger as more and
more information sources appear in modern enterprises. In many
situations a logical (rather than physical) integration of data is
preferable since some data is inherently not suited for storing in a
physically integrated data warehouse. Previous web-based data
integration efforts have focused almost exclusively on the logical
level of data models, creating a need for techniques focused on the
conceptual level. Extensible Markup Language (XML) is fast becoming
the new standard for data representation and exchange on the World
Wide Web, e.g., in B2B e-commerce, making it necessary for data
analysis tools to handle XML data as well as traditional data formats.
This paper presents algorithms for automatically constructing UML
diagrams from XML data and shows how to use the diagrams for the
conceptual design of (virtual) Data Warehouses based on web
data. Unlike earlier work, the focus of this paper is the support of
On-Line Analytical Processing (OLAP) systems based on web data.
