Distributed University Registration Database System Using Oracle 9i

Abstract

In database and information systems, increasing attention has been focused lately on parallel and distributed database systems. The future of large database systems lies into the realm of distributed computing. The main reason for this is that distributed computing can be constructed at a low cost without the need for any specialized technology, using existing sequential computers and relatively cheap computer networks. The basic motivations for distributed databases are improved performance, increased availability, share ability, expandability, and access flexibility. Oracle9i is one of the most famous database management systems that provide distributed features. Oracle9i supports transparent distributed gains to access data from multiple databases. It also provides many other distributed features, such as transparent distributed transactions and transparent automatic two-phase commit. This paper presents a distributed registration database system using Oracle9i distributed features such as replication and fragmentation. The analysis and design steps of the distributed registration database system are shown as well as to the practical steps required for implementing the distributed database system using Oracle9i.

An Enhanced University Registration Model Using Distributed Database Schema

“…The results of this study indicate that the distributed registration system behaves better performance than the centralized. These results are in agreement with those obtained from previous research work such as Sean Motta [6], 2010, Sana Alyaseri, 2010 [5], and Djam XaveriaYouh, 2010 [7]. To compare the performance of the two proposed systems, the average response time, average waiting time and the throughput are estimated.…”

“…Previous research tools that handle this issue are concentrated either on some colleges as in [6] by using the SQL server as a software tool. Or by studying the issue in a single university with various branches as proposed in [5] by using Oracle 9i. While the presented approach focuses on multiple universities in Jordan.…”

E-Management System of Kirkuk University Based on Distributed Database

“…a) In the administrator account, the administrator of the system determines the structure of the institution by adding the departments, branches, and units of the institution to the system. The administrator also manages the employees that are working on the system, by insert their information to the system, as well as assigning each employee to his/her special specified account which may be one of the three main accounts referring to in level 2 of figure (3). c) In the users (employees) account, each employee has this account whether he/she is a manager, responsible employee, or ordinary employee can display the list of outgoing documents that are sent by him/her and display list of incoming documents that received by him/her, for the purpose of reading the details of the document, editing for performing different procedures on the document, or attaching and uploading additional documents to the opened document.…”

“…So that it will be a good thought and good initiative to computerize any project [2]. Distributed computing is one of the most recent and important developments in the computing era [3]. Beside that the electronic management is a form of the contemporary approaches that seek to convert the traditionally institutions to electronic institutions using information technology (IT) in the managing all its transactions and managerial functions [4].…”

An Electronic Registration for Undergraduate Students with Department Selection Based on Artificial Neural Network

“…Thus, most Iraqi universities (public or private) actually strived to exploit the modernistic technologies like (web 2.0, mobile applications) in improving the students-universities interaction [1]. It can be also benefit from modern machine learning technologies in egovernment systems for predict new knowledge from huge amounts of distributed data depending on the hidden relationships and patterns of events that cannot be directly discovered by immediate human search [6].…”
