Development Of The Data-analysis System In The Observation Of The Shuicheng-dam Safety Based On SQL Server2000

Based on introducing the working theory of SQL Server2000 and the visiting-technology of Visual Basic accessing to SQL Server2000, the article gives the designing of the data-analysis system in the observation of dam safety using the normal data-analysis's method in the observation of dam safety. Development of the system will improve science, efficiency and intellect in the analysis to dam's observing data.The main researches in this paper are as follows:1. Thinking all kinds of interface-form through which Visual Basic visits SQL Server2000 current, the article selected the fitting technology-ADO;2. For the using after, the article created initial data-base and target data-base on SQL Server2000;3. Pre-treating to the observing data, including: the deleting unlawful data and the mending to the observing data;4. In-line analysis to data using mature correlating-analysis method;5. Creating the system of data-querying, picture-managing and user-managing which has luxuriant function in the Visual Basic program.
