the tables

can someone please tell me how many tables there was cause i did 3 i dont get how there would be 4 2 tables are the id's and the 3rd was the ref numeber one
There would be a forth table between staff and positions, as in the scenario it said that staff can have many positions during their tenure at the company and from the data given you can see that many positions can be held my many employees,(many employees had the same position) in the 4th table I think you’d have the Staff Ref, Position ID, position start and end date, hope that helps !
