Data Consistency and Concurrency Controlling in Air Ticket Selling in Different Sites by Using Notification- Reread Method (NRM) Khaing, Kyawt Kay Myint, Mu Mu In the database management systems,concurrency control is an important problem forthe simultaneous execution of transaction over ashared database can create several data integrityand consistency problem. In order to operatetransactions concurrently on a shared database, aconcurrency control algorithm must be adopted tocoordinate their activities. The concurrencycontrol of a distributed system is to ensure that theconsistency of the database. Nowadays, travellingindustry become stronger, enforcing travellingcompanies to run new branches in differentlocations.If users access a database concurrency,they may interfere with each other by attemptingto read or write the same data items. Therefore, itis important to handle the order of each branch.When a user updates some data that have beenaccessed by other users in database, or execute anundo/redo operation, data consistency willprobably be destroyed. In this system, a“Notification-Reread Method (NRM)” isintroduced to solve the problem caused byconcurrent processing. 2017-12-27 http://hdl.handle.net/20.500.12678/0000003294 https://meral.edu.mm/records/3294
