The management of changes made to the programs, documents, websites and other collection of information is called version control, revision control, source control and also known as Software configuration management. A system which manages these changes is called Version Control system.

Why We Need Version Control Systems?

Version Control Systems are the must component in our day to day life while managing, documents, computer, Programs and many more. One working without version control systems are like taking too much risk. Any changes while working with programs, websites are usually identified by revision number. whenever changes happen, the first instance is recorded as revision 1 and followed by revision 2, likewise, it goes on. You can compare, restore, merge those revisions.

Importance Of Version Control Systems

Version control system is an essential tool for the software team’s professional practices.When you change the code, the version control system is programmed to capture a snapshot of the files. VCS saves the snapshot automatically and so you can retrieve it later whenever you need it. Version control system places a vital role in their everyday life. VCS will capture each change made to the source code over time. Version Control System keeps track of every modification to the code.

Whenever the mistake is made, developers can easily identify when and by whom the mistakes are made. As we all know the source code is the most important thing for all software projects. So, whenever any changes or mistakes take place within the source code, version control systems helps developers to identify and compare earlier versions of the code to fix if any errors occurred.

Version Control System Vs Revision Control System

Version Control System runs as a standalone application, whereas Revision control is already embedded in word processors, spreadsheets and some web docs too. Some organization which runs multi-developer projects must need version control systems. Revision control also has the ability to recall a document to its previous state. It also tracks changes to the configuration files such as which are stored in /etc or /user on UNIX systems. This provides system administrators an easier way to track if any changes made and if needed, revert it to the earlier versions.

Revision control systems are most probably centralized, with a single authoritative data store, with the repository, and check-outs and check-ins done with reference to this central repository. Whereas in distributed revision control, no single repository is authoritative, and data can be checked out and checked into any repository. Merge is nothing but checking into a different repository.

Centralized Revision Control Systems

In centralized revision control system, all the revision control functions appear on a shared server.Imagine if two developers trying to change the same file at the same time, they may end up with overwriting each other’s task if there is no any method of managing access. Resulting in this, centralized version control systems solve this problem with the help of source management models namely file locking and Version merging.

File Locking

File locking is the simplest method to prevent concurrent access. Furthermore, it provides protection against difficult merge conflicts when a user makes changes to many sections of a large file. With this locking files models, only one developer at a time has to write access to the central repository.

Version Merging

When multiple developers edit the same file at the same time, the first developer who checks for changes to the central repository succeeds. Then the system will provide facilities to merge further changes into the central repository and preserve the changes from the first developer when other developers check in.
