Abstract
A configuration database includes multiple databases distributed at a plurality of physical locations within a process control system. The configuration database may include a master configuration database that stores all of the configuration data for all of the sites and one or more briefcase databases that download and reserve configuration data from the master database. The briefcase database is used at other sites to perform configuration activities and, thereafter, changed configuration items are promoted back to the master configuration database where these changed items are stored.
