Design and Implementation of a Course Selection System that Based on Node.js

Abstract

In this paper, a course selection system using single thread system and unified language is designed and realized, the system is easy to maintenance and stable in highly concurrent. The content include designing idea, system module and implementation methods. Node.js is used to improve the efficiency and reduce maintenance difficulty. Mongodb database is used to store large files, pictures, curriculum information, student information and other unstructured data, it can improve the efficiency of the system in a large degree. The result of test show that this course selection system is stable and efficiency. If change the course into person or things, the system will be changed into a personnel or an item management system for enterprise.
