+
+### Use MsSQL script to populate the benchmark database
+
+In order to create a database with a certain number of tables, and a certain number of records in each of them, 
+you need to follow a few simple steps.
+
+1. Create a new database.
+2. Follow the TODOs in **mssql-script.sql** to change the number of tables, and the number of records of different sizes.
+3. Execute the script with your changes for the new database. 
+You can run the script use the MySQL command line client: - **mysql -h hostname -u user database < path/to/script/mssql-script.sql**
+After the script finishes its work, you will receive the number of tables specified in the script, with names starting with **test_0** and ending with **test_(the number of tables minus 1)**.
