First, the basic information
Title: Design and implementation of student achievement analysis system based on data mining technology
Time: 2017

Key words: performance analysis; association rules; classification; clustering;
Second, research
A data file import: import address request and the user data file to a data file openfile, openfile of the structure has been defined in the system is initialized. After initialization, OpenFile Open a file and reads data from the file and stored in the structure. Loop this process until all the data is stored in the structure of the body, openfile close the file to the user output "Successfully imported file"
2 Data Preprocessing
3 association rules: First, what kind of criteria to determine whether there is a correlation two courses, the second is how to tap various courses of association rules
Category 4: Decision Tree algorithm to achieve the classification functions predict whether the primary predictor of all students have the risk of hanging branches, hanging branches and a relatively high risk of course.
Cluster 5: Using clustering algorithm to cluster the students, the students analyzed the association between school performance and achievements based on clustering results.
6 export file: export user address request and create a file of data to a file sent to creatfile, creatfile create a file in the specified address. After creating the file is completed, creatfile In turn, the results of the classification and clustering results array to read data from the storage association rules, sequentially stored in the file. Loop this process until all the data is stored in a file, the user is output to the "successful export data to a file."
CONCLUSIONS
This document and the first chapter is very similar, just on the achievements analysis step, more than the first document export and import files without much knowledge, not very helpful.
