Design And Implementation Of OA System Based On Cloud Services

Office automation systems named OA has gone through seven developments since it appeared from the 1950 s in the United States and other countries.OA concept changes into staff collaborative developmental work from the original personal work,the technology of OA also undergone a great innovation.With the development of cloud computing, cloud storage, wireless communication technology, OA has entered the mobile era, OA services have also entered into the cloud era.OA system based on cloud services with a simple deployment,soon to use,flexible select,enterprise can quickly change to the management of information technology through the cloud OA,more and more small and medium companies approve OA system based on cloud services.For the better development of OA industry,more companies can enjoy the convenience brought by technology,better enhance the work efficiency,that need to explore cloud service implementation of OA and design and implement a system based on OA cloud services.Relies on demand research,system identified multiple functional requirements including custom workflow and so on. The difficulty of system design and implementation are selecting cloud service implementations, custom workflow design and user access control, etc. By exploring cloud service approach system establishes three different ways of cloud services,solving the problem of the cloud-based services of OA system. Using abstract entity relationship,system completed data logic design of the workflow.Using control security, system solved the problem of user rights.Finally, relying on the.NET platform, complete implementation of the system.The testing of OA system based on cloud services suggests, system can support multiple users of different companies simultaneously access,can implement freedom workflow,can implement access control,can reaches the goals of distal access and backstage maintenance.
