Research And Application On Information Integration

Information integration is a system engineering that is general application on computer science, communication and network technology. Data acquisition is the hard core of data integration. Based on the current status and requirements of application, a solution for data acquisition that is suitable for mobile terminal unit is put forward in this dissertation.Some advanced technologies adopted by some popular products of information integration software are investigated and analyzed in this dissertation. Two data acquisition models based on mobile terminal unit is put forward in this paper. In this technical project, communication server provides with communication services for data server and mobile terminal unit. And data server manages the data which mobile terminal units transmit. Some problems in data communication subsystem have been deeply analyzed and realized, including network structure, communication protocol of application layer, the establishing of communication link, data structure of communication frames and its realization. Asynchronous network communication pattern is used to realize multitasking to meet the needs of data acquisitions based on multi-mobile-terminal-unit in each data server. And some problems in real-time database subsystem have been entered into and designed, including its structure configuration design, data management, the security of the system accessing and so on. Referring to the design idea of configuration software, the structure of real-time database is defined during designing real-time database subsystem. It is to enhance the flexibility in configuration of real-time database parameter and meet the application requirements. A storage method is put forward to solve the problem that stores real-time data about different storage cycle. The protocol of mobile terminal unit logging on communication server and data server is improved.In the end, the research and development of information integration software has been summarized. Several important issues need to be researched at next stage have been put forward in this dissertation.
