Abstract

<p>A Database is a collection of structured data describing the activities of one or more related organizations with a specific defined <br>purpose. Databases are controlled by Database Management System by maintaining and utilizing large collections of data. A <br>Distributed Database is a collection of multiple, logically organized databases distributed over a Computer Network. It is also a <br>collection of databases that can be stored at different computer network sites. This work presents an overview of Distributed<br>Database System: explaining why we distribute, what we distribute, and how we distribute. This paper classified distributed <br>database objects, stated various strategies for distribution and proposed a standard mathematical model for understanding, <br>interpreting and implementing the distributed database design method.</p>
