Software revision control is an important part of software development.
When we have to develop the large software project that must use many person, software
revision control will take an important role for this situation. Revision control or SCM
(source code management) is the software that have an ability to track and record the
change that happen to software development project and it will do this all the time of
developing the softwar project.

Revision control can also be used with document too.

The principle of revision control system is mostly use Optimistic Technique that is
the method to let many user can reach (Check out) to the same source code.Each user
(I mean programmer) can edit the source code that thay had download and can upload
(Check in / Commit) back to the Revision Control System. SCM has a responsibility to
check for the conflict of the data.The conflict data such as the situation that two user
edit the same file and still edit for the same fuction or the same line.Furthermore the
SCM has an ability to show the difference between the file in each version and can be
used for merge the two files altogerher. In SCM we have to build the Resository as the
data bank to store the data for SCM to use. In present there are many SCM software
such as SVN (subversion), GIT, CVS, Bazaar,IBM ClearCase, Perforce. SCM software also
has both commercial and non-commercial.

In the next article I will write about the comparison of revision control software
and the popular revision control software that are SVN (subversion) and GIT.
