+Whenever a query is made to the database server, all columns returned by
+the query are placed in the environment, using environment variables with
+the prefix "AUTHENTICATE_".
+ If a database query for example returned the username, full name
+and telephone number of a user, a CGI program will have access to
+this information without the need to make a second independent database
+query to gather this additional information.
This has the potential to dramatically simplify the coding and +configuration required in some web applications. +
