摘要：Information ambiguity and uncertainty are the major issues in real real-world scenario and for resolving these issues fuzzy data management has been incorporated in different database management systems in different ways. Even though there is much literature on XML-to-relational storage, few of these have given satisfactory solutions to the given problem of storing fuzzy XML data in RDBMs. In this paper, we attempt to present yet another technique for storing and querying fuzzy XML data in relational databases. The content XML document is retrieved using XPath. It views the XML document as a tree and uses one table that stores both the information contained in the nodes as well as the structure of the tree. We convert the XML tree representation into a table form using LOAD XML statement. We use SQL for query purposes. Also we can use crisp as well as fuzzy data for input in queries. We can also validate the XML input data using some unique key. It is a pre-defined key given at beginning of XML code. Further, we also propose a generic technique to convert path expression queries into SQL for processing XML queries.
