Answer 2

有具体要求么？真要写数据库？
我擦，数据库写出来这还叫平时作业？毕业设计都绰绰有余了吧

追问

是个小作业。。。但是有一堆零零散散的要求。。。

给了一个CSV的数据库，貌似要代入。。。

Answer 3

是使用数据库还是写数据库？有两种简易数据存储可以考虑
1、CSV
2、XML

追问

有个给定的CSV数据....

追答

给定了CVS文件，那么说来就是使用CVS作为数据源，也许需要再增加索引、主键等功能，可构成简单的文件型数据库。
如果还需要有结构化查询能力，那就要使用正则表达式分拆命令与数据，再调用相应的 CRUD 函数处理。
前面 luotuo512 已贴出代码，可实现非结构化的数据库能力，值得参考。
