Version Control System
When we say about the version control system it is a software which mainly used to tracks changes to a file or we can say a set of files. And whenever we need to recall some specific version now or later is possible. And this will also allows to work together with other programmers too.
The version control system is a collection of software tools which helps a team to manage changes in a source code. And this will uses a special kind of database to keep track of every modification to the code.
When we say about the developers that can compare earlier versions of the code with an older version to fix the mistakes.
Benefits of Version Control System
When we say about the benefits of version control system it is very helpful in software development. As it is always unsafe we have no version control system in software development projects. And VCS provides backups for uncertainty. Version control system mainly offers a speedy interface for a developers. This will also allows software teams to preserve efficiency and agility according to the team scales to include more developers.
key benefits of having a version control system are as follows.
- Complete change history of the file
- Simultaneously working
- Branching and merging
- Traceability
Types of Version Control System
- Localized version Control System
- Centralized version control systems
- Distributed version control systems
Localized Version Control Systems
When we say about the localized version control system it is a method which is uses a very common approach because of its simplicity. But due to this approach it will leads a very high chance of error. And in this approach, we may forget which directory we are in and accidentally write to the wrong file or we copy over files we don't want to do.
And to deal with this issue, programmers mainly develop a local VCSs that have a simple database. Such databases kept all the changes to files under revision control. A local version control system keeps local copies of the files.
One of the major drawback of Local VSC is that it has a single point of failure.
Centralized Version Control System
Here every developers needed to collaborate with other developers on other systems. Here our localized version control system failed in this case. And to deal with this problem we developed Centralized Version Control Systems.
And these systems have a single server which contains the versioned files, and some clients to check out files from a central place.
Whnen we say about the Centralized version control systems that have many benefits when we compare this with the local VCSs. Below are the benefits of Centralized version control systems:-
- Here in Centralized version control systems administrators have control over other developers.
- Here every developer or every team member has all the information about the work and what others are doing on the project.
- And when we say about the dealing with a centralized version control system than a localized version control system, centralized version control system is very easy to deal.
- A local version control system facilitates with a server software component which stores and manages the different versions of the files.
And here one of the drawback is that it has a single point of failure same as in local version control system. | |
