What is CVS?
CVS is actually the concurrent versioning system which is based on client-server Architecture. It is used for revision control systems.
It has a centralized repository, where the server-side modules are stored. The latest code has been fetched from the repository for editing the existing module and then updates the repository after the modifications.
The available tools for the CVS systems are as follows like Cervisia, Tortoise CVS, Emacs etc. The Graphical User Interface much more scalability and flexibility to the user as it is quite easy to handle with it.
What is SVN?
It is used as a client-server architecture based tool whose main function is version control and to manage files and directories. It allows sharing the changes, recovering older versions of data or examining the history of how data is changed.
A lot of highly skilled IDEs are now available with the SVN support. CLIs are also a handy way of managing tasks of SVN repositories. Repositories of software are uploaded to the server and users created for authentication using SVN configuration files.
As a User get verified new projects can be easily added to the repository using SVN client.
Difference Between CVS and SVN
CVS is based on RCS files of version control. Each file connected to CVS is an ordinary file containing some additional information.
The backbone of SVN is relational Database BerkleyDB composed of the set of binary files. It tracks the entire commit as a new version.
Atomic commit operation in concurrency environment is a problem in CVS. Whereas it is eliminated from SVN.
CVS allows rollback of any commit in the repository, even though this may need some time. SVN does not allow rollback of the commit.
SVN has a large application base while CVS does not have it.
For collaborative development, version control system is the must. The poorly engineered products are mainly due to the lack of proper tools. So employing this technology will surely enhance the development experience.
