Among others, data replication is one of the core of distributed database systems which make objects available to more than two database servers by physically copying objects stored in one to other database. Replication is synchronous • master/%laves databases need not to be connected permanently to receive updates from the master. means that updates can occur over long-distance connections and even over temporary or intermittent connections such as a dial-up service. Depending on the configuration, you can replicate all databases, selected databases, or even selected tables within a database. This research work presents the results from an application based on master-master synchronous database replication that allows platform heterogeneity. 'I Tie proposed approach is expected to be tolerant to faults as the data will always be available even in case of system (hardware/software) crashes. Furthermore, this research work also analyzes how queries are decomposed and distributed over geographically separate nodes and how consistent results be achieved. The experiments have been carried out on specially designed distributed environment by keeping in mind the future (efficient) uses of this implementation and its deployment at Quaid-e-Awam University of Engineering, Science and Technology, Nawabshah and Larkana campuses which still do not have their own distributed databases. The results are promising and it is recommended that the distributed databases be implemented at these campuses as well as at other such environments. xiii Department Of Information Technology Engineering https://tinyurl.com/5ac2hrc2 THESIS 0 0 0 0 RESEARCH RESEARCH 2016-11-23 0 MP/07-62 2016-11-23 00:00:00 THESIS 0 0 0 0 RESEARCH RESEARCH 2018-09-25 0 MP/22-225 2018-09-25 00:00:00 2018-09-25 THESIS
