taxicab booking ER model (was "Can sombody please help")

Hi All,

First of all thank you for thaking the time to read this.

I am currently studying for my DB Systems exam and I am doing a sample question - creating an ER Model then Relational Schema then creating the DB.

I have the ER model and Schema created but I am running into trouble normalizing it espically with the functional dependieics.

Could anyone take a look and advise me on the correct way to approach this?

Thanks again
