| Abstract: | Object-relational database technology combines the relational and object-oriented capabilities in one database system. It provides support for richer object structures and powerful query-oriented functions. This kind of DBMS can meet the requirement of some newly emerging application areas, such as GIS. Now, the Object-Relational DataBase technology is regarded as one of the most promising research and product development directions. This paper gives a method of accessing spatiotemporal vector data in an Object-Relational database. Results provide path of spatiotemporal data storage in Web environment. |
