在需求调查的基础上，结合网上商城系统的总体目标，对用户提出的需求从信息系统目标、业务功能、技术性能等方面分析，最终确定可行的、合理的系统功能需求。

根据以上分析，确定系统主要功能需求：

(1) 登录功能：用户输入用户名和密码，进行登录验证。

(2) 注册功能：可以查询用户名是否已经存在，对注册信息进行验证。

(3) 商品浏览：可以查询商品，显示商品详情，提供购买链接。

(4) 购物车管理：欲购买商品可以增添到购物车，也可以从购物车删除商品。

(5) 订单查询：用户登录后可以下订单，用户登录后也可以查看自己的订单。

(6) 商品种类管理：管理员可以对商品种类进行添加、删除操作。

(7) 商品管理：管理员可以添加商品、删除商品，查看所有商品。

(8) 订单管理：管理员登录后可以对订单进行管理。

(9) 用户管理：管理员可以管理注册用户信息。
