关于小程序云开发:基于微信云开发的幼儿园招生报名小程序

研发背景

• 以幼儿园新学期新学年招生报名为外围，
• 兼顾幼儿园环境图文展现（室内，室外，娱乐，起居等），幼儿园招生政策答疑，最新动静新闻，幼儿园食谱介绍，报名我的项目海报分享等，
• 目标是不便园方不便的统计幼儿注销材料，正当的管制报名人数，幼儿家长能够填写幼儿的根本信息，住址信息，监护人信息等材料（可自定义设置），
• 园方人员依据材料能够做事后审核，并提醒用户批改欠缺材料，并可查看和导出名单Excel，审核报名记录等，大大减少了现场报名的人力老本，数字化伎俩进步了工作效率， 也为家长节俭了工夫。

性能合成

技术使用

• 本我的项目应用微信小程序平台进行开发。
• 小程序自身的即用即走，适宜小工具的应用场景，也适宜疾速开发迭代。
• 云开发技术采纳腾讯外部链路，没有被黑客攻击的危险，安全性高且免保护。
• 资源承载力可依据业务倒退须要随时弹性扩大。
