这是我写的
因为英文太烂，写不了英文注释，说以在这补一下这个脚本的功能说明：这个脚本是统计书籍的订购量，订购用户数，浏览量等信息（以天为单位），这里的书籍，是按章销售的，所以记录的最小粒度是章节的订购量，订购用户，那么脚本就需要根据bookId为唯一标识，去累加各章（在某一天的）的数据，汇总到一本书下。基本流程是：
- 清理上次计算产生的临时文件
- 下载最新的数据到临时文件
- 统计 并将结果生成SQL脚本
- 执行SQL脚本入库
其中统计又分为
- 3.1从临时文件创建一个books数组（他是一个复合数据结构，每本书的属性都可以通过books[id,"属性"]索引）
- 3.2遍历章节销售记录，根据记录里的bookId写入对应的数据结构里
- 3.3生成SQL语句
