ClearCase vs Git

Difference Between ClearCase vs Git

In this topic, we are going to learn about ClearCase vs Git along with their key difference, comparisons, and features.

Definition of ClearCase

ClearCase is either a centralized or distributed SCM tool. IBM ClearCase is much appropriate for a small or simple code structure. However, for a large source code structure, its performance is very slow. Moreover, there are few good alternatives for larger source code for source control. Rational ClearCase is advantageous to handle the changes that are made in the version while uploading it to the repo to the specific branch. IBM ClearCase also manages parallel source code development of different dependent codes very appropriately.

Features of ClearCase

Below are a few features of ClearCase that are listed below:

• Push and Pull requests are handled well in ClearCase. They are much faster than Git.
• IP Protection.
• IBM ClearCase also manages parallel source code development. Here the merges take place in a secured format, as it is dependent on the branch present in the repo.
• Error Resolution: Any changes that are made in the repo while merging the code is been traced. This helps users to prevent any malicious or accidental activities.
• Best for managing versioning and branching.
• IBM ClearCase is best suited for small and simple source code systems where the push and pull requests are faster and efficient.

Definition of Git

Git is an open-source version control management tool that is a distributed model, primitive-open source system. GIT is preferable to be used for faster and high flexible services mostly when the code is going to be deployed. Git also provides an entire duplication of the repo on the user’s local workspace where the user has access to his local workspace and the centralized or main branch on the repository that helps to merge the specific branch that he is working on.

Features of Git

Below are a few features of Git:

• Easy to use: Git is simple and flexible to use to build and merge the code into the repository. It is much faster and is high availability during the production release.
• Free and open-source SCM Tool: Git is an open-source version control management tool that is a distributed model, primitive-open source system.
• Data Assurance: It requires a few additional tools to secure the data in the repository. Version changes are tracked and traced fully.
• Distributed Architecture: Git is a hash-based tool where all the merging of source code happens at the branch level.
• Maintains version changes in the history: Any changes that are made in the repo while merging the code is been traced. This helps users to prevent any malicious or accidental activities.
• User friendly: Git’s UI is user-friendly and the issues are handled by displaying the errors so that developers can resolve them easily.

Head to Head Comparison Between ClearCase vs Git (Infographics)

Below are the top differences between ClearCase vs Git:

Key differences between ClearCase and Git

• Architecture: ClearCase is a centralized version management tool while Git is a distributed SCM Tool. ClearCase is a file-based architecture whereas Git is a hash-based tool where all the merging of source code happens at the branch level.
• Performance: Git performs well comparatively than ClearCase. Git performs well at the developer’s level as it creates a repo from where all developers can clone it. When there is a large firm, ClearCase performance level slows down as it can create bottleneck performance and might fail at merging the code.
• Branching: Git offers a simpler branching method that is faster and efficient at its performance level. Branching in ClearCase is done on a file basis. There is a lot of manual effort need to branch the source code and thus it is time-consuming too.
• Flexibility: Git is simpler to set up and easy to maintain while ClearCase is difficult to maintain and for managing it, it will require an expensive administrative team.
• Security: Git requires the additional tool to secure the data but ClearCase has finite permissions to support data or files in the repository. Appropriate credentials are needed to access the repositories for ClearCase. ClearCase is a more secure repo tool than Git but it is quite expensive.
• Cost and availability Factor: Git is a free and open-source SCM tool. But Git also requires appropriate additional tools for better performance that is also chargeable. ClearCase is chargeable to maintain, use, and merge it into the repository.

ClearCase vs Git Comparison Table

Let’s see some more differences between ClearCase vs Git through a comparison table for clear understanding:

ClearCase	Git
ClearCase is a centralized version management tool and is a file-based architecture.	Git is a distributed SCM Tool and a hash-based tool where all the merging of source code happens at the branch level.
When there is a large firm, ClearCase performance level slows down as it can create bottleneck performance and might fail at merging the code.	Git performs well comparatively than ClearCase. Git performs well at the developer’s level as it creates a repo from where all developers can clone it.

Conclusion

ClearCase is difficult to manage from both developers and administrative points as it is complex to build and expensive to maintain. Large and small firms prefer to use Git to copy the code to the repository has it is free and open source. Though maintenance is chargeable, it is quite reasonable than ClearCase. In the above article, you can now compare the reasons why Git has taken up the gear from ClearCase and is been used by many companies.
