Thank you for reading this :) 1) Please use only CreateAndFillBase.sql to generate the database, since it also inserts all initial information. Also, I had some problems when tried to set onupdate and ondelete properties of a key in Workbench, so .mwb file does not contain those, however I did it manually in .sql file 2) Change database connection parameters in WebsiteFiles/php/db_class.php!
