 1.bookstore 文件夹是该项目的 demo，采用 Flask 后端框架与 SQLite 数据库，实现了前60%功能以及对应的测试用例代码。
 **要求大家创建本地 MongoDB 数据库，将`bookstore/fe/data/book.db`中的内容以合适的形式存入本地数据库，后续所有数据读写都在本地的 MongoDB 数据库中进行**

 2.在完成前60%功能的基础上，继续实现后40%功能，要有接口、后端逻辑实现、数据库操作、代码测试。对所有接口都要写 test case，通过测试并计算测试覆盖率（尽量提高测试覆盖率）。
 
 3.尽量使用索引，对程序与数据库执行的性能有考量
