WHAT IS GIT?
Git is a revision control system that is mainly utilized for software development and other version control tasks. It is designed for more speed, good data encryption and to support the distributed, nonlinear development. The most important thing about Git is, unlike a client-server system, every Git directory on every computer is actually a repository with complete history and is capable of full version tracking without relying on a central server.
SALIENT FEATURES OF GIT:
- NON-LINEAR DEVELOPMENT –
Git is compatible to swift branching and merging. Some definite tools in Git facilitate visualization and navigation of non-linear development history. A branch in Git is only related to a single commit. With its parental commits, the entire branch structure can be built.
- DISTRIBUTED DEVELOPMENT-
As we have already told, Git hands each developer a local copy of full development history. Changes are nothing but additionally developed branch which can be merged just like the locally developed branch.
- LARGE PROJECT HANDLING-
It is a rapid version control system. Getting version history from a local copy can be a lot quicker than getting it from the distant server.
- CRYPTOGRAPHIC AUTHENTICATION OF HISTORY-
The Git history is kept in such a way that the ID of a specific commit depends on the whole development history. After publishing, it is impossible to change the old versions, without it being recognized.
- GARBAGE ACCUMULATION AND COLLECTION-
In a database, many useless objects are left after aborting an operation. More often than not, these are small fractions of continuously growing history when sufficient dangling objects are created in a repository. It automatically accumulates and collects this garbages.
WHY SHOULD WE USE GIT?
When it comes to version control, why are we talking about Git so much? Of course, all that things glitter is not gold. But here are the top 9 reasons why you should use it-
- WORK OFFLINE-
So you need to work but you are stuck in traffic. With a centralized VCS, you are stranded. But don’t worry, Git lets you do that – you have the local copy to make a commit, browse your history, merge the branches-everything is possible.
- SAVE TIME-
GIT is lightning fast. In other VCSs, a command is associated with a few seconds delay. Git is much quicker because operations are local and no network lagging is present. So, performance is better.
Git permits a group of people working together, all using common files. In this scenario, many conflicts are bound to arise but Git makes it easier to deal with them.
- UNDOING MISTAKES-
Git is there with an ‘undo’ command wherever possible. One can edit his/her commits, introduce small changes. Reverting an entire commit is not required. One can even recover ‘deleted’ commits. Because Git seldom deletes anything.
- PROGRESS CLEAR-
Git helps you to avoid disorders and create granular commits. The staging area is really a feature that is one of a kind, where one can decide specifically what changes shall be included in the next commit at a microscopic level.
- MY WORK, MY WAY-
In Git you are using your own workflow. That does not mean you can not work on a central repository like subversion. In both ways, all the benefits remain unchanged.
- SMALLER SPACE REQUIRED-
Unlike SVN, working directory of Git is extremely small. Less disk space is required per working copy. This is because a full Git clone is generally smaller than a full checkout.
- CREATIVITY AND EXPERIMENTATION-
Git branching enhances your code quality and productivity. Git offers you a free environment, where you can make mistakes, undo it, explore and develop your new ideas. There is no fear of harm to the current version of a project. All these make your project more innovative.
- NO DATA LOSS ANYMORE-
Losing data and not being able to recover it, is a horrible experience. It’s good that in Git, every developer working on a project has a full-fledged copy in their machine, containing full change history. If your backups break down, losing data is not a chance, because you can restore it from other member’s local repository.
From the above points, it will not be an exaggeration to say that, not only Git is a superb version control system, but also it is a brilliant way to think how to get the work done. Overall, Git defines the role of VCS in a creative toolkit.
