MapViewer Architecture
{"Image DocumentName": "MapViewer Architecture", "Image ImageDescription": "Client. (browser, servlet, JSP, PL/SQL) Application. Java API. XML/HTTP. Oracle Application Server. Map Rendering Engine. JDBC. MapViewer Architecture. Client applications connect to MapViewer and send XML mapping requests via the HTTP communications protocol. Requests include information about which database to query, and also information about the map to be drawn. MapViewer connects to the database using JDBC, fetches information about the map to be drawn from the map metadata tables, then selects the spatial data to be mapped by performing spatial queries. MapViewer then renders the map, and the response to the map request sent back to the client for display is a streamed map or a pointer to the map along with the bounds of the map. Database. Spatial.
