一、前言
随着互联网的普及和电子商务的快速发展，越来越多的人选择在网上购买商品。鲜花作为一种典型的礼品，其销售也受到了很大的影响。传统的实体花店存在很多局限性，比如时间和空间的局限、信息不对称等问题，这使得许多消费者无法方便快捷地购买到心仪的鲜花。因此，开发一款基于移动设备的网上花店微信小程序/安卓APP，可以更好地满足消费者对鲜花购买的需求。
本选题旨在开发一款基于移动设备和网络技术的网上花店微信小程序/安卓APP。通过该应用程序，用户可以随时随地浏览和购买鲜花，同时还可以享受多种便捷的服务，比如在线支付、订单跟进、订单评价等。该应用程序将拓宽花店的业务范围，提高销售额和客户满意度，同时也可以为消费者提供更加便捷的购物体验。
目前，一些网上花店已经采用了线上销售系统，但是这些系统存在一些问题。首先，部分系统的使用门槛较高，需要消费者具备一定的技术能力才能使用；其次，部分系统的鲜花信息展示不够详细，无法满足消费者个性化需求；部分系统缺乏对服务质量的监督机制，导致服务质量参差不齐。这些问题都严重影响了网上花店的效果和质量。
本课题的研究目的是设计并实现一款基于微信小程序/安卓APP的网上花店系统，以提高网上花店的效率和质量。具体来说，该工具可以实现以下功能：1. 提供便捷的鲜花信息展示和管理功能，方便消费者进行信息查询和选择；2. 实现订单管理和支付的便捷性和个性化需求满足，让消费者得到更好的服务体验；3. 提供售后服务和投诉处理功能，确保消费者的权益得到保障。通过以上功能的实现，可以解决现有解决方案存在的问题，提高网上花店的效果和质量。
