Any large scale system is designed to store and keep track of really huge information sets that will always keep on growing. One of the factors that have to be tracked down to the least bit in these information systems is the change and information changes represent the overall transformation of the information systems. The changes also show how information has been flowing within the large scale system and which components of the information have seen change and which haven’t been changed at all. There are several means through which the information changes that are happening in large scale systems can be tracked down and this means that one can always be made aware of when the changes are happening and what gets introduced into the systems.
Snapshots of an information system often get taken to compare how the information looked like a few minutes ago and at the present moment. This also means that for huge databases, the snapshot will be a representation of the current signature of all the information that is within the large scale system. Any tiny change to the information means that the overall structure of the information will also have changed which also changes the meaning of the information on the system. Serious information system administrators have to learn how to handle and deal with the information on their system by keeping track of all the changes which are happening to the system in real time.
Keeping track of the changes is similar to the way in which large scale software projects take place in the modern world. These software projects have many people working on the same code base and whenever one of the programmers makes a contribution to the system, the change gets to be reflected across the entire system. The changes are tracked by use of a version control system which notes down all the simple changes that have been happening in the code of the software being worked on and what was modified. This makes it possible for the software project to revert to a snapshot of the code that it was using before the changes were introduced.
For information changes in large scale systems, the operating principles are the same and the same version control can also be used to keep track of the changes that are done on the information sets. These changes have to be tracked and noted so that in the event that there are some changes that need to be undone, the system can always target such changes individually while the rest of the information stays intact without losing its meaning and value. The integrity of the information system in the large scale architecture will also include all the simple and complicated changes that have gotten introduced to the system.
In brief, any information changes that happen to large scale systems have to be noted and kept track of in order to maintain a state of the information that can revert changes and undo bad changes which are updated based on the metadata of the change.
