SSB（Star Schema Benchmark）是麻省州立大学波士顿校区的研究人员定义的基于现实商业应用的数据模型，业界公认用来模拟决策支持类应用，比较公正和中立。
学术界和工业界普遍采用它来评价决策支持技术方面应用的性能。
全方位评测系统的整体商业计算综合能力，对厂商的要求更高。
在银行信贷分析和信用卡分析、电信运营分析、税收分析、烟草行业决策分析中都有广泛的应用。
SSB基准测试包括：
1个事实表：lineorder
4个维度表：customer，part，dwdate，supplier
13条标准SQL查询测试语句：统计查询、多表关联、sum、复杂条件、group by、order by等组合方式。
SSB数据生成器
SSB数据自动生成器下载地址：点击这里
实验证明，在Linux上操作比较方便，步骤如下：
- 将下载的文件上传至Linux主机上的目录
- 执行如下命令，生成dbgen文件：make
- 查看 dbgen 命令帮助： ./dbgen -h
- 生成数据文件，命令如下：
(customer.tbl)
dbgen -s 1 -T c (part.tbl)
dbgen -s 1 -T p (supplier.tbl)
dbgen -s 1 -T s (date.tbl)
dbgen -s 1 -T d (fact table lineorder.tbl)
dbgen -s 1 -T l (for all SSBM tables)
dbgen -s 1 -T a- 生成文件如下： ll *tbl -l
- 连接mysql数据库，创建数据库，数据表
- 创建数据库： create database ssb;
- 创建数据库表：
