Your database (peq) is full of tables, columns and values, which you will need something to log on and edit your database. There are many tools out there available, but that's a seperate learning process in itself. You may have gotten heidisql with your install ? maybe ?
Some use the EOC, peq editor, navicat, etc. There is a section in these forums with resources, as well as looking at the gitbook wiki:
