1. A process control system comprising: a server; and a database system in data storage that is accessible to the server, the database system including a set of tables that contain process representations, a process representation indicating a current status of a process that is being controlled by the system; a set of tables that contain query representations, a query representation indicating a particular query over the set of process representations; a set of tables that contain administrative activity representations, a query representation further being related in the database system to an administrative activity representation indicating an activity performed on each process representation that belongs to a result set produced by the particular query indicated by the related query representation, and a set of tables that contain action representations, an action representation being related in the database system to an administrative activity representation and indicating an action executed when the related administrative activity representation's activity is performed, an action representation further being related to a trigger representation in a set of tables that contain the trigger representations, a trigger representation relating a query representation to an administrative activity representation, wherein the server utilizes the sets of tables in selecting one of the query representations for execution, executing a first particular query indicated by the selected query representation, performing the related administrative activity on each of the process representations in the first particular query's result set, determining that an action representation related to the associated administrative activity is a trigger representation, executing a second particular query indicated by the query representation related to the trigger representation, and performing the administrative activity represented by the administrative activity representation related to the trigger representation on a result set of the second particular query, wherein the result set of the second particular query includes process representations which are not included in the result set of the first particular query.

The process control system set forth in claim 1 wherein: the server always performs the administrative activity represented by the administrative activity representation that is related to the trigger representation on the result set of the second particular query.
