Sakila for SQLite is a port of the Sakila example database available for MySQL, which was originally developed by Mike Hillyer of the MySQL AB documentation team. 
This project is designed to help database administrators to decide which database to use for development of new products
The user can run the same SQL against different kind of databases and compare the performance
