Spatial Database Tips and Tricks Workshop¶
Mapping APIs are great for data display and capture, but how do you build applications that allow query and geoprocessing of spatial data without becoming a Java or C++ programming guru? How about using the power of SQL, the standard database query language, and the spatial extensions provided by SQL Server, Oracle Spatial and PostGIS.
