一、前言
随着社会经济的发展和科技的进步，大学生兼职已成为一种普遍的现象。越来越多的学生希望通过兼职来提高自己的技能水平，丰富社会经验，赚取生活费用，为未来的就业做好准备。然而，在这个过程中，学生、商家和管理员面临着许多问题，如信息不对称、申请过程繁琐、审核效率低下等。因此，开发一款基于微信小程序或安卓APP的校园兼职平台显得尤为重要。
目前，市场上已有一些校园兼职平台，但它们存在着一些问题。首先，信息不对称现象严重，学生很难获取到真实可靠的兼职信息。其次，申请过程繁琐，学生需要填写大量的申请表格，而商家则需要手动审核每一个申请者。再次，审核效率低下，往往需要花费很长时间才能完成审核。这些问题导致了学生和商家之间的沟通不畅，降低了整个兼职过程的效率。
本课题旨在开发一款针对大学生校园兼职的微信小程序或安卓APP，解决现有解决方案存在的问题，提高兼职过程的效率和质量。具体研究内容包括：
1）兼职信息管理：学生和商家可以发布和浏览兼职信息，管理员可以对信息进行审核和管理；
2）兼职申请与审核：学生可以提交自己的兼职申请，商家可以对学生的申请进行审核，管理员可以对申请进行管理；
本课题的研究意义在于：
1）提高兼职过程的效率和质量：通过微信小程序或安卓APP，学生和商家可以更方便快捷地进行沟通，管理员可以更好地管理兼职信息和申请；
2）提高学生的社会适应能力：通过使用该平台，学生可以更好地了解社会需求，提高自己的技能水平和社会适应能力；
3）为商家提供兼职资源：通过该平台，商家可以更方便地找到符合自己需求的兼职人员；
4）为学校提供更好的管理工具：该平台可以为学校提供更好的管理工具，如统计兼职人员的数量、分布和管理情况等。
