Database Structure

[Maarten Hendrikx]

Hi,

We're planning a web application which
will allow teachers to plan their teacher diary online.
So for instance:
Mondag 8.50 - 9.40 --> Math (First Grade)
Mondag 9.40 - 10.30 --> French (Sixth Grade)
And so on for an entire week.
We have made some simple applications using only
a limited number of tables. But we're having some
trouble with the database structure for this one.
More specific: we're guessing we can't use one table
for the entire week schedule of all the teachers. But
do we have to make a new table for every teacher or
a new table for each day?
We would appreciate it if somebody could advise us
on our database structure.

Thanks,
MJ
