SOFTWARE CHANGE MANAGEMENT, CONFIGURATION SUBSTITUTION AND REMOTE ADMINISTRATION OF DATACENTERS

摘要

Change management in a relational database may be implemented by indexing changes by copying the database to a new revision when a change is made to one or more items in the database. The new revision may be committed as a single unit and all changes stored together under a single revision. Database users may be notified of the new revision that is available for use. Software configuration issues may be simplified through the use of a configuration language that separates the logical configuration between software components from the specific configuration of those components. Secure data center administration may be handled through the use of control hosts.
