摘要:
Developments towards information technology in which it becomes the part of daily life nowadays, the need for a database system supporting the processing of information becomes inevitable again. The database system is required to always be ready to provide the data to the quantity and types of data are more frequently large increasingly and varied, which will further raise up the number of databases that must be well managed in terms of time, cost and effort. In addition, to minimize these conditions, there is a solution i.e., using Distributed database replication system. By utilizing a database replication system, then performing the database system can be improved by utilizing each client as a master and a slave at once, so that if one server is crashed there will be other servers available functioning as a new server so that the data availability could be guaranteed. © 2017 American Scientific Publishers All rights reserved.
