Providing shared-memory abstraction in messagepassing systems often simplifies the development of distributed algorithms and allows for the reuse of sharedmemory algorithms in the...
Temporal document databases are interesting in a number of contexts, in general document databases as well as more specialized applications like temporal XML/Web warehouses. In or...
Changes in the real world may require both the database population and the database schema to evolve. Particularly, this is the case in CAD/CAM and CASE database systems, in which...
Considerable progress has been achieved in the area of virtual database systems, but substantial problems still persist. In this paper we discuss two current research directions: ...
In this paper we will present the two basic operations for database schemas used in database mapping systems (separation and Data Federation), and we will explain why the functoria...
