Study On Datawarehouse And Data Mining Technologies In Teaching Management System Of High School

Data warehouse and data mining is a database of research, development and application of one of the most active branches. Data Warehouse can extract the relevant external data and internal data integration, the unified transmission of information to all levels of users. Data mining is the huge amounts of data looking for potential correlation between the data and found that ignore factors.All colleges and universities to continuously improve teaching quality, each school students through the network to end the teachers teaching quality assessment of the school under the points at the scheduled formula for each of the teachers' rating. However, has ignored the students at the time may be due to various factors, there is a great discrepancy between the assessment, such as different professional teaching students points standards should not drive, therefore, in a certain extent, these rating results do not fully reflect the real objective, comprehensive and practical teachers teaching standards. To resolve this issue, the article in the data storage and data mining technology in teaching management system of the applied research.This paper introduces the concept of database and data mining, combined with teaching management system of teaching quality assessment system and method of data mining technology. Teaching assessment using data warehouse for data organization tools, focusing on the ID3 decision tree algorithm, association rules in the classical algorithm - Apriori algorithm in teaching quality assessment system. Teaching evaluation data through data mining and teachers to find out the inherent laws of teaching effectiveness and key factors, so that play a real role in guiding assessment.
