| Abstract: | With the help of data mining for education and examination information,education management and decision can be made scientifically.The characteristics of the education and examination data are analyzed,and snowflake model for the data marts of college entrance examination is designed.Algorithm Apriori is used for the association rule mining to find the grade relationships among different subjects of college entrance examination.Results show that the grades of different subjects have compact association,and the minimized support thresholds are all larger than 75%. |

| Keywords: | data warehouse data mining snowflake model association rule education and examination database |
