A replication model for students´ result processing

Distributed data stream processing has been gaining increasing research attention in recent years. Data continuity and massiveness has made it is critical and challenging to design a scalable and efficient dissemination system. Thus, a system that enables changes in database to copy or duplicate from one physical location or system to another (typically from a master to a slave system) is pertinent. The need to improve on the weaknesses of the traditional system of disseminating students´ results in tertiary institution such as security of classified information amongst others led to the design and implementation of replication system of disseminating results. The design was done using dissemination tree mode and the work provides an efficient way of disseminating results and it also improved upon the traditional system by ensuring the security of data contained on the root and overlay servers.
