What is clearcase

The increased complexity can be addressed by employing software configuration management SCM tools and processes. SCM helps development teams capture, control and securely manage software changes and assets throughout the software delivery life cycle.

Choosing the right SCM tools is critical for effective configuration and asset management. The SCM system should be capable of:. IBM Rational ClearCase software offers comprehensive software configuration management and change management capabilities that facilitate sophisticated version control, workspace management, parallel development support and build auditing to help improve productivity.

Designed to improve collaboration and automation, it can help businesses enhance IT efficiency by lowering business costs, mitigating risk and reducing time to market for high-quality solutions.

It organizes its code repositories as a versioned object base VOB , which contains the versioned file and directory elements.

But why Git is called a distributed version control system? This is because everyone working on a project in Git has a copy of the full history of the project. Technically, there is no centralized authority to determine the official version of the repository. ClearCase, on the other hand, is a centralized version control system meaning it keeps the history of changes on a centralized server. Each user has their own view of data in the VOB on which they are working.

Git would require multiple repositories for the same volume of files. Multiple repositories is the only way to work independently in Git and to support multiple courses of work that are isolated from each other but are still highly interdependent. Managing a whole project becomes difficult.

And Git has a powerful merge feature that takes the independent line of development created by git branch and integrates them into a single branch. So, merging in Git is super fast. This is not the case with ClearCase, which is a little less efficient when it comes to merging. GitHub allows you to collaborate much more easily with other people on a project. One of the main differences between the two is the repository design; ClearCase organizes its repositories as Versioned Object Bases VOB , whereas multiple repositories is the only way to work independently in Git.

GitHub has a much powerful merging feature than ClearCase. So, both have their fair share of pros and cons. ClearCase is a powerful source code management and Software Asset Management SAM tool for version control, which like other version control systems including GitHub, tracks and manages changes across the entire development lifecycle.

Git is a distributed version control system whereas SVN boasts a centralized model meaning the history of changes over time is stored on a central repository. Git is a distributed version control system based on a decentralized model, whereas Perforce is a self-hosted version control system based on a centralized model. CVS is centralized version control system, while Git is based on a distributed model. CVS is definitely one of the most reliable and efficient version control systems out there.
