Abstract

Based on the study of XML documents storage in Oracle XML DB, this paper conducts a research on extending Oracle XML DB to store and manage GML documents. Meanwhile, owing to the defects that the XML DB cannot support the spatial index, an external R-Tree index is added to Oracle database to improve the efficiency of GML spatial query and operation. At the same time, with the help of NTS as well as with Oracle´s own support XQuery, the spatial extension to XQuery in Oracle is proposed and implemented. Through the research of this paper, we provide a solution of GML database for GML storage, index and query.
