DISTRIBUTED DATABASE
Abstract:
Distributed databases are becoming more widespread, fueled by advances in technology and demand for system availability. The purpose of this paper is to present an introduction to distributed databases, issues related to the motivations of DDBS, architecture, design, performance, concurrency control, database links, advantages and disadvantages of distributed databases.
A distributed database is a database that is under the control of a central database management system (DBMS) in which storage devices are not all attached to a common CPU. It may be stored in multiple computers located in the same physical location, or may be dispersed over a network of interconnected computers.
A key objective for a distributed system is that it looks like a centralized system to the user. The user should not need to know where a piece of data is stored physically.
