摘要
网络的广泛应用给生活带来了十分的便利。所以把少儿编程管理系统与现在网络相结合，利用java技术建设少儿编程管理系统，实现少儿编程的信息化。则对于进一步提高少儿编程管理发展，丰富少儿编程管理经验能起到不少的促进作用。
少儿编程管理系统能够通过互联网得到广泛的、全面的宣传，让尽可能多的用户了解和熟知少儿编程的便捷高效，不仅为群众提供了服务，而且也推广了自己，让更多的群众了解自己。对于少儿编程而言，若拥有自己的系统，通过系统得到更好的管理，同时提升了形象。
本系统设计的现状和趋势，从需求、结构、数据库等方面的设计到系统的实现，分别为管理员和家长的实现。论文的内容从系统的设计、描述、实现、分析、测试方面来表明开发的过程。本系统根据现实情况来选择一种可行的开发方案，借助java编程语言和MySQL数据库等实现系统的全部功能，接下来对系统进行测试，测试系统是否有漏洞和测试用户权限来完善系统，最终系统完成达到相关标准。

Abstract
The wide application of network has brought great convenience to life. So the children's programming management system and the network is now combined, using Java technology to build children's programming management system, to achieve the information of children's programming. For further improve the development of children's programming management, rich children's programming management experience can play a lot of promoting role.
Children's programming management system can be widely and comprehensively publicized through the Internet, so that as many users as possible understand and know the convenience and efficiency of children's programming, not only to provide services for the masses, but also to promote themselves, so that more people understand themselves. For children's programming, if you have your own system, through the system to get better management, while improving the image.
The present situation and trend of the system design, from the requirements, structure, database and other aspects of the design to the realization of the system, respectively for the realization of administrators and parents. The content of the paper shows the development process from the aspects of system design, description, implementation, analysis and testing. The system according to the reality to choose a feasible development plan, with the help of Java programming language and MySQL database to achieve all the functions of the system, then the system is tested, test whether the system has vulnerabilities and test user permissions to improve the system, the final system to achieve relevant standards.
