Answer / tanveer ahmed
To resolve the many - many relations, one has to broke
cardinalities of either tables... for example Student and
Teacher tables, you can clearly oberserves that One student
will have many Teachers and vice varsa one teacher can have
multiple students too....
so one must have broke the either cardinality of student or
teacher.... like example broke the table of Teacher into
two sub-tables and join the accordingly....
Please refer some good books for understanding how to
define bridge table first for this....
Thanks...............

Answer / anik
generally many -many relationship comes when there is a
problem in your model . try to see if you are missing any
Query Subject which might have a relationship with both the
query subject which is creating many to many relationship .
for avoiding cross join too we have to specify the
correct relationship between the query subjects
