摘要：As known, the most greater part of the systems GISs that come projected today have the ability to use for the data management the Geodatabases, or rather spatial database whose principal characteristic is that to model the geographical data using the object paradigm. Unfortunately such type of modeling, able to maintain the bank dates consistent and efficient, it is implemented in the various softwares GeoDB alone in the layer of representation (and with limited functionality), or of user interface; on the contrary, in data storage, you deals with DBMS servers using a relational approach. This choice not only implies an important fall in the system performances, but the representation inside a GIS of the contexts endowed with notable dynamism becomes complex, in fact in such cases the data management (population and quering) you must have effected to every level through operational interfaces endowed with a tall degree of abstraction. In consideration of these facts, we develop an alpha OODBMS server, named "Kosmos", oriented to GeoDatabases, differently from all other DBMS softwares. Kosmos making passes through a preliminary step in which we are going to define an algebraic structure and a rigorous formal model to describe GIS objects and functional operators acting on these objects. Kosmos, thanks to these characteristics, it allows a simple management and at the same efficient time of database geographical spatio-temporal, is for instance possible to effect some operations of geoprocessing (intersect, union, etc…) multi layers - multi temporal, tracking areale and to define some relationships spatio-temporal between features. Software design follows the Open Source philosophy; in particular, Kosmos is released under GPL license and anyone can take part in its coding.
