This is a relational way to store application configuration in a table. It uses two tables, so you can store multiple configurations, so that you can use the tool over and over, and still retain the old settings. One table stores configurations, and one stores a since row with the current configuration in use.

Setting values are retrieved from the configuration tables with queries like this:
(SELECT PreRegActivityID FROM Congress7_Config WHERE ID=(SELECT CurrentConfigID FROM Congress7_CurrentConfig))
