This isn't a law chiseled in stone, but most of the time, you'll have a much easier time of it if you use just one table. You can then use finds, relationships, portal filters and sorts to work with specific sub sets of your data (churches, schools, individuals). This really comes into play when you consider how your two differnt group categories interact. (Let see all church prospects...). You'd have a pair of category fields (one for churches, schools, individuals and one for Prospective or Actual customers.) Moving record from one category to another becomes as simple as updating a category field instead of copying the entire record from one table to another. With a single table, you can also easily create reports where you see your data grouped into sub categories and with sub totals computed for each.
