The Study And Practice Of Enterprise Mobile Applications

The migration applies obtains the application in very many domains. Because its response fast, operation simple, suitable outdoors, and so on. In recent years, along with the development of network technology, the maturity of wireless standard, the construction of telecommunication network, the custom demand to moved work day by day increase. The development of mobile applicaition became a new hot spot in software development. But because the hardware of mobile equipment existence limits greatly, CPU speed, storage size and multimedia processing performance far low compared to table PC. Adds the types of terminal device are many. The operating system, the infrastructure platform are not unified, Therefore the mobile application has its characteristic in the development tools and the method of exploitation.Afer earring on the analysis and the comparison of the mainstream develop platform and the development tools, in view of carried on the development designs on the majority mobile develop platform the design was complex, the programming was tedious, the code test was difficulty and so on, this article chose The .NET platform, and uses based on .NET Compact Framework carry code programming, The code programming simplified the difficulty and the work load greatly.The article carried on the discussion on system design, database design, development process, etc. and developed a application based on .NET platform: The wireless orders food system, it include the onstage orders food subsystem,the backstage system manage subsystem and the data synchronization subsystem. Through the process of architect design, detailed design, code programming and test, has discussed the general step of mobile application development. The system uses SQL SERVER CE database, realized the offline data storage. According to the preservation, Carry on the data synchronization when the motion database and the backstage database, beforehand majority motion application uses the method is carries on the condition mark to each data record, stable and the reliable comparison is short of, meets when the data conflict isdifficult to judge and processing. Through the research, in view of above flaw.The article proposed one kind of improvement plan: The merge replication, and confirmed this plan feasibility throngh the programming and the test.In research results foundation, this article has carried on the design and coding, has realized the mainframe and function of system, and has carried on the test. The test result indicated this system easy to operate, stable is reliable, has proven the mobile application is usability.
