Time stamps and CRCs
Time stamps and CRCs both help maintain database integrity, but they do it differently. Time stamps change whenever a table schema is updated or recreated at another time or place; CRCs change only when certain schema elements critical to field or record definitions change. As long as a table is structurally compatible with the r-code that references it, the CRCs match and the r-code can execute. It does not matter when or where the table's schema was created or updated.
