Overview

The real world we live in is mostly perceived through an incredible large collection of views generated by humans, machines, and other systems. This is the view reality. The Opsis project concentrates its efforts in dealing with the multifaceted form and complexity of data views including data projection views, aggregate views, summary views (synopsis), point of view views, and finally web views. In particular, Opsis deals with the generation, the storage organization (Cubetrees), the efficient management (Dynamat), the update and maintenance (Dynamat, Online Updates), the creation from remote data sites (MOCHA), broadcasting (Air Cache), and the availability and scalability of view systems (Transcurrent Execution Model).
