An implementation of web services for inter-connectivity of information systems

As educational institutions and their departments rapidly increase, a communication between their end-users becomes more and more difficult in traditional online management systems (OMS). However, the end-users, i.e., employees, teaching staff, and students are associated to different sub-domains and using different sub-systems that are executed on different platforms following different administrative policies. Because of their intercommunication is not automated integrated, consequently, the overall efficiency of the system is degraded and the communication time is increased. Therefore, a technique for better interoperability and automated integration of departments is an urgent needed. Many of existing systems does not have a set of connections yet, such as the system of the University of Sindh (UoS). In this paper, we propose a system for the UoS, named integration of inter-connectivity of information system (i3) based on service oriented architecture (SOA) with web services. The system i3 monitors and exchanges the student's information in support of verification along heterogeneous and decentralized nature. Moreover, the proposed system provides capability of interoperability between their sub-systems that are deployed in different departments of UoS and using different programming languages and database management systems (DBMS).
