Need to check the ER diagram is correct

Thanks for your quick and excellent response. What I wanted to know is; is it suitable to have a staff table as well as the three separate tables for the staff titles, or should there be a only the staff table as you have described above. I am in the process of 1st Normalisation of the database and therefore need to retrace the steps backwards from your solution.

Here is what I have observed from the client:

Three staff members work at the client studios; including studio managers, drivers and sound engineers but some members of staff can be allocated to more than one studio. Every studio has a studio manager. The driver is given a van and these vans are under the responsibility of the drivers they are given to and not shared among drivers. Sound engineers ensure customers are provided with the right type of equipment for the music work that they want to do and that they can use it appropriately to get the best value out of it. Furthermore, each engineer oversees a certain number of customers so that to ensure that all the customers have a first point-of-call in case they have any problems. Also each engineer is responsible for a certain number of pieces of equipment which they closely look after. One more point to mention is that pieces of equipment are registered under a specific studio’s name so that a record is kept of which studio is ultimately responsible for it.

Thanks for your help and efforts

thanks very much! excellent solution
