而随着互联网技术的不断发展，互联网已经渗入到我们生活中的各个方面。移动设备的普及使我们的生活发生了翻天覆地的变化，这种变化也深刻影响着我们的日常生活。微信是腾讯公司在 2011年所发布的一款实时通讯软件，随着互联网技术的不断发展，微信的功能也不断得到扩充。微信目前已经成为了一个“航母级别的软件”，也是每个智能手机上必备的软件之一。直到 2017 年“微信小程序”的发布，也成为了业界的一股热潮。微信小程序的使用无需安装，使用时只需要扫一扫或者搜一搜，用完即走。微信小程序针对于用户来说，无需在手机上下载软件，只要是有微信这个软件即可使用。针对于小程序开发者来说，微信小程序开发时可直接调用自带的 API接口，开发时较为简单，节省时间人力与物力。与此同时，小程序也可以实现与原生 app 一样的流畅体验。

本课题题目是小程序的免税店平台的设计与实现。本文从系统开发环境、系统目标、设计流程、功能设计等几个方面进行系统的总体设计，详细阐述了一个功能较完善的免税店系统的前后台开发、操作流程和涉及的一些关键技术。介绍了系统的需求分析，系统分析，具体完成了数据流分析，数据字典功能模块的划分，数据库的设计和界面设计。最后对系统进行了测试分析，以保证其性能的稳定性和功能的完整性。

Abstract

With the continuous development of Internet technology, the Internet has penetrated into all aspects of our life. The popularity of mobile devices has made our life change dramatically, which also has a profound impact on our daily life. Wechat is a real-time communication software issued by Tencent in 2011. With the continuous development of Internet technology, wechat has been expanded. Wechat has become a "carrier level software" and one of the necessary software on each smartphone. Until 2017, the release of wechat applet has become a hot trend in the industry. Wechat applet use does not need to install, use only need to scan or search, use up to go. Wechat widget pin for users, do not need to download software on the mobile phone, as long as there is wechat software can be used. For the small program developers, the API interface can be called directly when developing wechat applet. It is relatively simple to develop and save time, manpower and material resources. At the same time, the applet can also achieve the same smooth experience as the native app.

The topic of this paper is the design and implementation of time management applet based on wechat platform. This paper designs the system from the aspects of system development environment, system objectives, design process and function design, and elaborates the development, operation process and key technologies of a community management system with perfect functions. The paper introduces the system demand analysis, system analysis, data flow analysis, data dictionary function module division, database design and interface design. Finally, the system is tested and analyzed to ensure the stability of its performance and the integrity of its functions.
