Abstract : 
As databases applications become more and more diversified, the capabilities of the 
current commercial database management systems developed on the basis of handling formatted data 
become less and less satisfactory. We are interested in image databases. We propose a query langage 
for image databases. The image data (bitmap or graphics) are organized in hierarchie of inheritance. 
Operators on image are identified and associated with differents classes of image. The query langage 
is an object oriented SQL. It uses classes and methods defined in the hierarchie of inheritance. The 
langage combined with the hierarchie of inheritance provide a powerful environement for any kind of 
image application.
