Abstract
A system useful for controlling a process includes a computer-readable medium and a processor in communication with the computer-readable medium. The system further includes a first database and a second database. The first database stores first data representative of a first configuration of the process, while the second database stores second data representative of a second configuration of the process. A configuration routine of the system is stored in the computer-readable medium and configured to be executed by the processor to facilitate a modification of the first configuration of the process. A version control routine of the system is stored in the computer-readable medium and configured to be executed by the processor to store in the second database third data indicative of the modification of the first configuration of the process.
