Service-Centric Object Fragmentation for Efficient Retrieval and Management of Huge XML Documents

Vast amount of XML documents raise interests in how they will be used and how far their usage can be expanded. This paper has two central goals: 1) easy and fast retrieval of XML documents or relevant elements; and 2) efficient and stable management of large-size XML documents. The keys to develop such a practical system are how to segment a large XML document to smaller fragments and how to store them. In order to achieve these goals, we designed SCOF model (service-centric object fragmentation model), which is a semi- decomposition method based on conversion rules provided by XML database managers. Keyword-based search using SCOF model then retrieves the specific elements or attributes of XML documents, just as typical XML query language does. Even though this approach needs the wisdom of experts in XML document collection, SCOF model makes it efficient both retrieval and management of massive XML documents.
