But we do not believe that they provide a solution for the types of objects mentioned above. Interactive computing is towards commodity desktop and notebook devices. They will be heavily used for histogram manipulation and data presentation.
Data clustering is organized around objects and containers of objects.
They are not designed to access only a subset of the object attributes. We have demonstrated with the PAW column-wise ntuples the usefulness of having access to single attributes. OO data bases do not support on the fly data compression. We are designing experiments that will generate massive amounts of data. The cost of direct access devices for tens of terabytes may be a dominant factor in the cost of computing.
