ABSTRACT:
A relational database management system having an XML storage implementation to reduce overhead associated with consuming data from multiple data providers, where each having proprietary database schemas. The XML storage solution allows data from any arbitrary relational database schema to be loaded, rearranged and retrieved. The present invention is directed to an implementation of an edge table such that large volumes of XML data of any structure can be stored effectively. The edge table may be designed as one large XML document where the schema information is stored separately from the instances, and relationships and constraints are expressed using foreign keys. The edge table further provides for full type support and validation. Indices and clustering provide efficient data access and query execution.
