A sample database with an integrated test suite, used to test your applications and database servers
This repository was migrated from Launchpad.
See usage in the MySQL docs
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.
You need a MySQL database server (5.0+) and run the commands below through a user that has the following privileges:
SELECT, INSERT, UPDATE, DELETE,
CREATE, DROP, RELOAD, REFERENCES,
INDEX, ALTER, SHOW DATABASES,
CREATE TEMPORARY TABLES,
LOCK TABLES, EXECUTE, CREATE VIEW
Then run
mysql < employees.sql
If you want to install with two large partitioned tables, run
mysql < employees_partitioned.sql
After installing, you can run one of the following
mysql -t < test_employees_md5.sql
# OR
mysql -t < test_employees_sha.sql
For example:
mysql -t < test_employees_md5.sql
