Secondly, it benefits greatly the data dissemination and data sharing based on Internet. The most important but not the last is that we can establish the information service network supported by its technologies and the facilities of information highway. So, it would be significant to design IBIS to realize the data collection, sharing and dissemination on Internet. There are many factors affecting regional environment. So it is not easy to realize the integrated environmental monitoring. Given this, we designed the Internet based environmental monitoring information system. By the virtue of the Internet based environmental monitoring information system, the management and storage of environmental monitoring data would be easier, which lays the foundation to actualize the environmental monitoring efficiently.展开更多

High-tech technology has brought a lot of conveniences to people's lives. High-tech is also widely used in people's daily lives. The society has entered the "internet plus" era. Among them, the management of hospital personnel files has gradually become information-based with the help of high-tech technology with the development of the times. Under the environment of the "internet plus" era, The progress of science and technology has provided a more convenient management mode for hospital personnel file management, improved the quality and level of hospital personnel file management, brought into play the advantages of informatization, solved practical problems, provided more opportunities for hospital personnel file management and realized the informatization and modernization of hospital file management.展开更多
