| Distributed databases are becoming very traditional now a days. Today’s company environment has an increasing need for distributed database applications as the need for reliable, scalable and accessible information all the time more getting higher. In addition, that system provides an advance on communication and data processing suitable for its data distribution throughout different network sites. Not only is data access faster, but the error rate is low when they happen, and it provides local control of data for users. In general, the definition of a Distributed database is a collection of databases that can be stored at different computer network sites. The inadequacies of centralized database systems and manual systems in managing students’ exams require the use of distributed database systems in this paper. The proposed system is a relational database designed in a technique that each academic department in the university has its individual database. The master database is hosted at Center processing unit exams. In this paper, we build a network between parts of the system in order to achieve sharing of information with each other. Three-Tier architecture is the methodology that is used to design and implement the system. The proposed system architecture includes three tier architecture and the Database Management System (DBMS) which combine in a web application. | ||
