ClearCase is a version file system masquerading as project version control. It's heavyweight, clumsy, and brittle, and it's easy to get yourself in an inconsistent state.<p>At one enterprise in my past it could take months to merge for release, during which time the entire repository was locked for everyone. I suspect it was the 30 years of commit history. It took years to move to something more modern.<p>Much better than Microsoft [Visual] SourceSafe.
ClearCase is the worst source control system that I've had the displeasure of using. I'm not sure what "DevOps Code ClearCase" is (latest/rebranded version of ClearCase?), but I expect that it's a raging dumpster fire of lost productivity with UX from hell.
