Abstract: There is a logically centralized level global data centers to meet the global schema database for centralized storage needs. This will not only ensure efficient query dataset brings advantages, without compromising the autonomy of each data source. Logically centralized layer needs to have at least a central database, data dump module. This paper studies storage and query system of legal documents based on the information integration system and its implementation methods, the application can be completed more intelligent reasoning queries.

Abstract: The research and applied technology about agriculture are attracting increasing attention, and especially digital greenhouses have become an important part of efficient agriculture. In this paper, basing on the environmental factors and crops growth status information, management system sorts out, analyzes and summarizes the data to give the best environment parameters for different crops in different external environment and to give the best growth parameter value for crop in different growth stages. A standard database of digital greenhouse will be built in this paper. Basing on the database, automatic identification and query model will be built. The system will provide daily operation schedule for crops during the whole growth of crops. And all kinds of growth parameters information in the process of crops growth will be analyzed by the system. Then the system compares the crop growth situation with standard database and sends the abnormal information to users timely. Simultaneously, real-time video monitoring can be used. Some daily routine work information can be recorded and suggested, such as watering, fertilizing and weeding etc. Based on crops growth and development patterns, the environment conditions are controlled and high quality, high yield, and efficient cultivation of plants will be realized.
