Knowledge Discovery in Databases (KDDs) is an important task in spatial databases since both, the number and the size of such databases are rapidly growing. This paper introduces a set of basic operations which should be supported by a Spatial DataBase System (SDBS). Here, it will go on to describe the research that is currently going on in this area, pointing out the different areas, tasks, etc. Finally, this will helps the researchers to develop better techniques in spatial databases.
