Efficient algorithms for managing the history of evolving databases,g any past state of a database. This theoretical framework therefore reduces the problem concerning the history management of databases to the problem of efficiently managing the history of a set evolving in time. We present a dynamic algorithm that reconstructs the state of the set at a given time

Removing redundancy and updating databases,rm (or some other normal form like Boyce-Codd Normal Form). This method of database design assumes that the real world satisfies very strong constraints like . (fds), without any exceptions..Most databases in “Whatever” Normal Form still contain a large amount of duplicated information, because the

A flexible and adaptable tool kit approach for concurrency control in non standard database systemshat address the concurrency control issues of ‘advanced database applications’ like, e. g., CAD/CAM, CASE, large AI applications or image and voice processing. The demands on concurrency control in such application areas differ substantially from those in traditional database applications; in partic
