into aggregated and residual view elements or by spatially partitioning the lattice data further taught are an apparatus and a method for generating a view element data representation including the decomposition of the lattice data by iteratively and jointly aggregating and spatially partitioning the lattice data under the system for representing the data using view element sets costs and benefits are assigned to the view elements and the view element sets are formed on the bases of the costs and benefits a view of the data from a set of view elements is synthesized by selecting view elements from the view element sets and assembling the view elements together to construct the views application_number US 28858099 A description fig1 depicts a networked client server system having features of the present invention as depicted a client 110 and server 111 are interconnected by a network 101 a server 111 includes a conventional database management system dbms 102 and direct access storage devices dasd 103 a 103 x through a user application 100 the user issues queries to be processed at a server 111 a query is typically prepared on a client machine 110 and is submitted to the server 111 through the network 101 a query typically interacts with the database management system 102 for retrieving or updating the data stored in an associated dasd 103 a for example an on line analytical processing olap engine 104 may receive queries involving aggregated views of the data in the dbms 102 those queries involving aggregated views of the data.
