+# Star Schema Benchmark
+
+## Introduction
+
+- [dbgen](./dbgen) comes from [electrum/ssb-dbgen](https://github.com/electrum/ssb-dbgen), thanks to [electrum](https://github.com/electrum)
+- What is SSB: [Star Schema Benchmark](https://www.cs.umb.edu/~poneil/StarSchemaB.PDF)
+
+## Build
+
+```sh
+cd dbgen
+make -j8
+cd ..
+```
+
+## Data Generation
+
+```sh
+cd dbgen
+# "-s" is used to specify the volume of data to generate in GB.
+# "-T a" indicates dbgen to generate data for all tables.
+./dbgen -s 1 -T a
+cd ..
+```
+
+## DataBase and Table schema generation
+```sh
+mysql -h 127.0.0.1 -P 4000 -u root -e "drop database if exists ssb;"
+mysql -h 127.0.0.1 -P 4000 -u root -e "create database ssb;"
+mysql -h 127.0.0.1 -P 4000 -u root -D ssb < create_table.sql
+```
+
+## Load Data
+
+```sh
+mysql --local-infile=1 -h 127.0.0.1 -P 4000 -u root -D ssb -e "load data local infile 'dbgen/part.tbl'      into table part      fields terminated by '|' lines terminated by '\n';"
+mysql --local-infile=1 -h 127.0.0.1 -P 4000 -u root -D ssb -e "load data local infile 'dbgen/supplier.tbl'  into table supplier  fields terminated by '|' lines terminated by '\n';"
+mysql --local-infile=1 -h 127.0.0.1 -P 4000 -u root -D ssb -e "load data local infile 'dbgen/customer.tbl'  into table customer  fields terminated by '|' lines terminated by '\n';"
+mysql --local-infile=1 -h 127.0.0.1 -P 4000 -u root -D ssb -e "load data local infile 'dbgen/date.tbl'      into table date      fields terminated by '|' lines terminated by '\n';"
+mysql --local-infile=1 -h 127.0.0.1 -P 4000 -u root -D ssb -e "load data local infile 'dbgen/lineorder.tbl' into table lineorder fields terminated by '|' lines terminated by '\n';"
