Difference Between ClearCase vs Git
In this topic, we will learn about ClearCase vs Git, along with their key difference, comparisons, and features.
ClearCase
ClearCase is either a centralized or distributed SCM tool. IBM ClearCase is much more appropriate for a small or simple code structure. However, its performance is very slow for a large source code structure. Moreover, there are a few good alternatives for larger source code for source control. Using Rational ClearCase is beneficial in managing version changes and uploading them to the repository for a particular branch. IBM ClearCase also appropriately manages parallel source code development of different dependent codes.
Features of ClearCase
Here are some features of ClearCase:
- ClearCase effectively handles both push and pull requests. 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 depends on the branch in the repo.
- Error Resolution: When merging code, the repository tracks any modifications made. 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 more efficient.
Git
Git is an open-source version control management tool, a distributed model, primitive-open source system. For faster and more flexible services, it’s recommended to use GIT, especially when deploying code. 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, 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 made in the repo while merging the code are 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 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, creating a repo from which all developers can clone it. When there is a large firm, the 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 more efficient at its performance level. Branching in ClearCase is done on a file basis. There is a lot of manual effort needed to branch the source code; 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 an additional tool to secure the data, but ClearCase has finite permissions to support data or files in the repository. To access the repositories for ClearCase, you must have the necessary credentials. ClearCase is a more secure repo tool than Git, but 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 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, the 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, creating a repo from which all developers can clone it. |
| ClearCase is chargeable to maintain, use, and merge into the repository. | Git is a free and open-source SCM tool. But Git also requires appropriate additional tools for better performance that is also chargeable. |
| Access to repositories in ClearCase requires appropriate credentials. ClearCase is a more secure repo tool than Git, but pretty expensive. | Git requires an additional tool to secure the data, but ClearCase has finite permissions to support data or files in the repository. |
| Branching in ClearCase is done on a file basis. There is a lot of manual effort edneeded to branch the source code; thus,, it is time-consuming too. | Git offers a simpler branching method that is faster and more efficient at its performance level. |
| ClearCase is difficult to maintain, and for managing it, it will require an expensive administrative team. | Git is simpler to set up and easy to maintain. |
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 as it is free and open source. Though maintenance is chargeable, it is quite reasonable than ClearCase. In the article above, you can compare why many companies now prefer using Git over ClearCase.
