I have a problem with following excercice :

For a school I would like to design a normalized database model for the
surveillance during different times a day on different places by different
teachers.

- There are different places
    Tables => Places (Placen°, placename)
                Placen° is the primary key

                => Teachers (Teachn°, teachersname)
                 Teachn° is the primary key

                => Surveillancemoments(Survn°, Date, Begintime, endtime)
                    Survn° is the primary key

Note : it must be possible to have different surveillancemoments for each
place.

                => SurveillanceTeachersLink(Teachn°, Survn°)

Note : for each surveillancemoment, different numbers of different teachers
must be possible too.

I'm trying to make a prototype-construction in MS Access, but, I don't get
out of it.

It seems my model is not correct. What do I forget/mistake?

Thanks for any help,
EDS
