都市供求信息网分为前、后台两部分设计，前台主要实现信息的显示、搜索与发布功能，其中信息的显示包括列表显示与详细内容显示，而列表显示，又分为首页信息列表显示、查看某类别下所有信息的列表显示和搜索结果列表显示；搜索功能主要包括定位搜索和模糊搜索。后台主要实现的功能为信息显示、信息审核、信息删除、付费设置与退出登录，其中的信息显示功能也分为列表显示与详细内容显示。(Supply and demand information network before the city divided into two parts design background, foreground main achievement of the display, search and publishing of information, which displays information including a list of displays and display details, but the list is displayed, the information is divided into the Home display list, see Under a category displays a list of all the information and the search results list displays Search functions include positioning search and fuzzy search. The main function of the background information display, information auditing, information deleted, pay setting and exit the registry, which is also divided into the information display function displays detailed contents list display.)
