3.2 系统分析
系统分析初步界定了系统的范围和功能。为了有一个更加清晰的开发思路，现用自然语言对整个虚拟金融信息化交易系统进行详细地描述。
1.总述
该虚拟金融信息化交易系统主要有我的首页、我的持仓、交易明细、账户信息、用户注册、用户登录、安全退出和金融搜索八大功能模块。用户在注册该系统之后，只需输入自己的用户名和密码，即可登录到该系统进行金融信息查询、金融买入、金融卖出、交易明细查询、个人信息修改等操作。除此之外，该系统还提供了丰富翔实的金融、财经链接，以方便用户(游客也可以)进行浏览和学习。
2.分述
接下来，本人将对上述功能模块进行详细的描述。
1、我的首页：亦即系统首页，任何游客或者是已经进行注册了的用户都可以浏览。在我的首页中囊括了丰富翔实、精彩纷呈的网页内容。其中有颇具人性化的网站欢迎标语，随着时间和用户的不同会发生细微的变化；优美精致的网站Logo，简洁大方的搜索栏，贴心实用的天气预报，当然肯定少不了丰富多彩的网站链接，包括站内的图文资讯和热门TAG，还有站外的新浪财经、金融之家和金融入门等等。
2、用户注册：浏览了如此精彩的首页，如果你想驻足，享受更多、更精彩的体验的话，你可以马上点击“用户注册”链接，进入用户注册页面进行注册。当然你必须遵循一定的规则才能顺利完成注册，比如为了确保账户安全、有效，页面上的六个输入框用户名、密码、重复密码、邮箱、手机号码和联系地址都必须正确地填写，否则你有可能无法完成注册。
3、用户登录：如果你已经顺利完成了注册，那么系统将会自动跳转到“用户登录”页面，你可以马上尝试登录。这里只需要正确地输入你的用户名和密码，就可以成功地查看到你的金融持仓、金融信息化交易明细和个人信息，这个时候，你将有权对这些模块进行相关操作。
4、我的持仓：用户在成功登录到该系统后，将可以对此模块进行操作。在此模块中，用户可以查看到自己金融持有信息、价格信息，还可以进行相应的金融信息化交易。
5、交易明细：用户在成功登录到该系统后，可以到交易明细模块查看自己的金融信息化交易即金融代码、金融名称、金融价格、金融数量、交易类型和交易时间的具体情况。
6、账户信息：用户在成功登录到该系统后，同样也可以进入账户信息模块，查看和修改自己的个人信息，其中包括用户姓名、登录密码、邮箱、手机号码、联系地址和注册日期，但注册日期是不允许修改的。用户修改后，点击表单下面的“确定”按钮，即可完成个人信息的修改，然后页面会跳转到登录页面，要求用户重新进行登录。
7、金融搜索：为了增加用户的体验，方便用户查询自己感兴趣的金融信息，在系统的每一个页面都设置了同样的搜索栏。无论用户正在浏览哪个页面，只要在搜索栏中输入你想要查询的金融代码，就可以轻松快捷地搜索到所需要的金融信息和相关的持仓信息。而且这项功能同样也对非用户的游客进行开放，但游客并不能得到相关的金融持仓信息。
8、安全退出：如果用户完成相关体验后，想要退出该系统，可以点击“安全退出”按钮，页面会自动跳转到登录界面。本文转载自http://www.biyezuopin.vip/onews.asp?id=14023在不重新登录的情况下，用户跟普通游客一样，不能浏览我的持仓、交易明细等页面。
3.3 总体功能模块
该虚拟金融信息化交易系统，主要是为了满足用户对金融信息化交易的体验，要求操作简单快捷、界面整洁大方，因此必须要设计一个好的程序架构和运作流程。从上述系统描述中可以大致了解到整个虚拟金融信息化交易系统的总体功能模块划分及流程图概况。如图3-2、3-3所示。
