Distributed databases: Security, consistency, and replication

In the last decade there have been significant changes in the computer industry. In database systems, we have seen a widespread acceptance of the management of relational databases for traditional business applications such as order tasking, inventory control, banking operations and flight bookings. However, the management of existing relational databases have proven inadequate for applications whose requirements are quite different from those of the database type applications to traditional business. These applications include: computer aided design (CAD), computer aided manufacturing (CAM), computer aided software engineering, information systems and office and multimedia systems, digital editing, geographical information systems.
