We present a new approach to the grid technology that is based on updateable views. Views are used in two ways: (1) as wrappers of local servers that adopt local schemata to the federated database requirements; (2) as a facility for intelligent data integration and transformation into a canonical form according to the federated database schema. Views deliver virtual updatable objects to global clients. Objects can be associated with methods that present the procedural part of remote services,

Such a quality is achieved by applications based on CORBA. We attempt to achieve a higher level of transparency by providing means for integrating horizontal and vertical fragmentations of data and by taking into account various forms of data redundancy. The approach is based on a very simple and universal architecture and on the stack-based approach (SBA) to object-oriented query languages.
