技术：ssm
| 现如今，信息种类变得越来越多，信息的容量也变得越来越大，这就是信息时代的标志。近些年，计算机科学发展得也越来越快，而且软件开发技术也越来越成熟，因此，在生活中的各个领域，只要存在信息管理，几乎都有计算机的影子，可以说很多行业都采用计算机的方式管理信息。信息计算机化处理相比手工操作，有着保密性强，效率高，存储空间大，成本低等诸多优点。针对电脑硬件库存信息管理混乱，出错率高，信息安全性差，劳动强度大，费时费力等问题，采用电脑硬件库存管理系统可以有效管理，使信息管理能够更加科学和规范。 |
| 电脑硬件库存管理系统采用了模块化设计方法，采用Java语言进行编程设计，MySQL数据库进行数据存储和管理，JSP技术进行系统页面设计。根据电脑硬件库存管理的需求开发功能模块，实现对信息数据的添加、删除、修改、查询等基本操作，能够极大的提高电脑硬件库存管理效率。通过本系统可以实现电脑硬件库存管理的全过程，本系统主要的功能模块设计包括：用户管理，硬件类型管理，硬件管理，出入库订单管理，系统公告管理等。 设计和实现电脑硬件库存管理系统，需要学习和掌握Java语言、JSP技术、MySQL数据库等关键开发技术，并且熟练使用IDEA .Tomcat等相关的开发工具。 |
