A database management system should support views to facilitate filtering of information in order to have only necessary and required information available to users with minimal delay Although a lot of research efforts concentrated on views within the conventional relational model, much more effort is required when object-oriented models are considered. However, supporting views is only a step forward in achieving the purpose that requires improving the performance of the system by considering incremental maintenance of views instead of recomputing a view from scratch each time if is accessed.
