What will you do when you have that you have to add more groups and delete other groups? Are you
going to redefine the dimementions of your array and the assignment of your array indexes as
records are added and deleted to your groups table?
A "many to many" table is really a relationship between two or more entity tables. The groups
table would know nothing about members and members would know nothing about groups. They way to
determine the relationship between members and groups is to query across the relationship table.
This is a time test any univerally accepted model for (Relational) database systems.
