Store SVG Document in ORDBMS

Because of big SVG document storing spatial data in WebGis, the searching by attribute is low efficiency and need the high quality hardware in the client. In order to solve the two problems, by making use of the rules mapping DTD of SVG document to relation schema extended for being fitted for SVG document, we complete storing SVG document in object-relational database. Finally, we realized management of the spatial data by tag document to by objected relational database and achieved the expected results.
