Research And Design Of Statistical Mobile Office System Based On MobiLink

With the rapid development of economy, it is an urgent need to access the necessary data at any time, any place。The "mobile office" concept was put forward under this circumstance and become a new hot spot of software development。People pay more and more attention to "Mobile Office". The mobile database is the foundation and the key to mobile office. Mobile Database has an enormous market demand and a widely application prospect in e-commerce, smart home, automotive equipment and other fields.Statistics Department is specialized on information and takes charge of plenty of Resources of information. It is an urgent need to use modern information technology for effective development and scientific management. Although infrastructure of the computer hardware and the development of software systems have made great progress, the Statistics Department still does not use "Mobile Office".The subject aims to design a Statistical Mobile Office System based on MobiLink synchronization technology .This system will be used in mobile terminal equipment. The statistical staff can build their mobile office based on this system.. They can access the data on the Main Server Database based on their authorities and work with the data on their mobile terminal equipments, Then the data will be uploaded to the Main Server Database to maintain the consistency between the Main Server Database and the Mobile Terminal Database.In this paper, the development and the status quo of mobile database is analyzed at first, with explaining the significance of this issue. Then the research and analysis of the Sybase database system and MobiLink synchronization techniques are introduced. In the last part of this paper, the general framework and detailed design of the system as well as some key techniques are introduced, which include designing the Main Server Database according to the feature of the statistical data, designing the Mobile Data Table according to the needs of the Mobile Office, designing script for different staff so they will get different data from Main Server Database, and proposing solutions for errors or conflict which could occur in the synchronization process. The notification procedure of MobiLink Server has many restrictions, so the technology of PushMail and XML are introduced in this system to push data to the mobile device from Main Server Database. The system function and performance are tested and summary is made at the end.
