In the application of GIS data and the development of the GIS, vector data、raster data、attribute data and cartographic symbols not only can't be managed easily, but it also reduce the efficiency. Oracle Spatial is the application extension of Oracle database on the storage of spatial data. As it has been developed for about twenty years, at present, it provides powerful support for the storage and operation functions of vector data、raster data and attribute data, it also provides import tool and developer components for these three kinds of data above. However, it can't satisfy the needs of the clients for it doesn't provide cartographic symbols management tool and it can't extend cartographic symbol library. In order to realize the integrated storage of vector data、raster data、 attribute data and cartographic symbols, this paper elaborates the design and construction of a visual symbol library management system for Oracle Spatial data, this system can realize the import and management from SVG format to Oracle. Practical applications show that the tool provides convenient way for the display of spatial data and web visualization; it also can cooperate with Oracle Builder import tools and Oracle Map server, and become an effective complement of a series of Oracle Spatial tools.
