Implementing Samples' Classfying Analysis By Using Matlab, SQL Server And Visual Basic

Air quality has become one important indicator which can evaluate the city's living standard. At present,most of the cities have built the supervising network which conects the city station,enterprise station,and linked section station.In this network,most of the pollutant data is stored in the server side, this is quite convient for the management of the pollutant data. However,the data analysis for the pollutant data still rests on stand-along calculating level, which hasn't reached the level of directly classifying data from the database in the client/server structure, such way needs a lot of manual input when facing such huge data stored in the database,it is quite inconvient.This text's main point is Classifying Analysis method, Classifying Analysis has been broadly applied in biology,medicine, geology and weather region.Environmental classifying analysis is one important branch of the environmental mathematical model,its main task is to study the data's classifying, It has a great importance in the environmental implementing area.In the pratical environmental supervising work, a lot of analysis data is stored in the database, when calculating big amount of data, the stand-along software are less of the ability of remote-transfering the data. So how to calculate the result by using the computer tool is the problem that we must face and solve. We choose the client/server structure to solve this problem.So this research emphasize on the development of data collection and classifying analysis by using Visual Basic, Matlab, SQL Server2000.This will enhance the efficiency of environmental data analysis.Adopting this project not only can reduce the complex data input work by using the Matlab's Toolbox function, but also can enhance the management of the SQL Server database, This research has a profound effect on the theory and applying value of software development of several different environmental models.
