Research And Application Of Synchronization Mechanism Based On Mrtmors

The advancement of mobile database system meets the requirement of data process in mobile computer environment, and the maintenance of data consistency is the main problem to resolve in the application of Mobile database. Traditional data processing mode can not meet the needs of mobile computing environment for the great difference between mobile computing environment and stationary distributed computing environment. Therefore, to maintain data consistency to establish what kind of data synchronization mechanism is important in mobile computer environment.The paper firstly describes the characteristics and development of Mobile database synchronization mechanism. Based on the popular data synchronization mechanism which uses transaction result set as its granularity of synchronization, we study a new data synchronization mechanism which uses mobile related-transaction merge to optimization result set as its granularity of synchronization. Mobile terminal submit the mobile transaction which change data after merger, which change the drawbacks of submitting mobile transaction one by one in the past. At the same time uses a conflicts detection and resolution mechanism based on transaction timestamp.That we used sync services for ADO.NET which is the latest data synchronization framework of Microsoft has realized the data synchronization mechanism based on mobile related-transaction merge to optimization result set. We solved the data synchronization of client and server. The paper discusses the conflicts detection and resolution in detail.Finally the paper elaborated that the data synchronization mechanism based on mobile related-transaction merge to optimization result set has applied practically in warehouse management system. We analyze the functions and workflow of warehouse management system and specific application of data synchronization management.
