本文档介绍了如何配置和加载MySQL的employees测试数据库，该数据库包含约30万员工记录和280万薪资条目。数据由Fusheng Wang和Carlo Zaniolo在Siemens Corporate Research创建，Giuseppe Maxima制作关系模式，Patrick Crews导出为关系格式。数据中存在不一致性和问题，被保留下来作为数据清理练习。通过执行SQL脚本完成数据库结构创建和数据加载，验证结果显示数据库和表已成功创建。

说明

employees是mysql官方提供的测试数据库，具体介绍如下：

The original data was created by Fusheng Wang and Carlo Zaniolo at Siemens Corporate Research. The data is in XML format. http://timecenter.cs.aau.dk/software.htm

Giuseppe Maxia made the relational schema and Patrick Crews exported the data in relational format.

The database contains about 300,000 employee records with 2.8 million salary entries. The export data is 167 MB, which is not huge, but heavy enough to be non-trivial for testing.

The data was generated, and as such there are inconsistencies and subtle problems. Rather than removing them, we decided to leave the contents untouched, and use these issues as data cleaning exercises.

配置employees数据库
