Abstract

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%.

Key words: data warehouse, data mining, snowflake model, association rule, education and examination database

摘要： 进行教育考试数据挖掘与分析研究，有利于充分发掘教育考试数据的潜在价值，更好地为教育管理、教育决策提供科学的依据。分析了教育考试数据资源现状与特点，构建了高考数据集市雪花模型，采用Apriori算法生成频繁数据项集，并以最小置信度75%为条件，挖掘出考生4科高考成绩之间的关联规则。
