Enhanced protection level by database replication in the easy-learning online platform

This paper deals with optimization of the database for the Easy-Learning online platform. It supposes knowledge in environments of web programming, databases, high tech devices and graphical design. The basic technologies that were used in the platform are Apache web server, PHP dynamic pages and MySQL databases. With the help of the replication of the database, the problems of defective hardware system components and the problem of distribution of data were solved. The Easy-Learning platform has now a back-up database on a separate machine connected to the network that is synchronized automatically with the main machine. The original contribution of this paper consists in showing how ingenious an e-learning platform can get a back-up database on a separate machine connected to the network and automatically synchronized with the main machine.
