These are thoughts From Bill M. in August of 2009;
The people group paradigm is most useful when the following conditions are met.
For quite a while, I have been thinking about the people in country perspective. In 2002 we developed a flat database of the worlds peoples to place on the Internet. By flat I mean that the database was one table and had no relationships. During that development we took out the people in country perspective leaving only one record per people group.
