Abstract: The overall XML file length is one of the critical factors when we need to transfer a large amount of data from relational database into XML. Especially in the nested tree structure of XML file, redundant data in the XML file can add more cost on database access, network traffic and XML query processing. Most previous automated relational to XML conversion research efforts use directed graphs to present relations in the database and nested trees in the XML structure. However, they all ignore that different combinations of tree structures in a graph can have a big impact on the XML data file size. This paper addresses this nested structure data file size problem. It proposes a module that can find the most convenient tree structure for the automated relational to XML conversion process. It provides a plan generator algorithm to list all the possible tree structures in a given directed weighted graph. Also it analyzes the data size of each plan and shows the convenient tree structure t o the user. It can finally create the targeted XML documents for the user. (More)
