Pinned topic Comparing CC with VSS

‏2006-01-18T08:01:28Z |
Hello CC Gurus,

I am eager to know the difference between ClearCase and VSS. Just wondering Why ClearCase is number 1 SCM Tool?

Your Valuable suggestions are appreciated.

Thanks in Advance,

    Have a look at the Ovum report "Summary of the configuration management
    evaluations"
    (http://www.serena.com/Shared/pdfs/dimensions/Ovum2005_Summary.pdf).
    For almost all evaluation criteria ClearCase is at or close to the
    top and VSS is at or close to the bottom.

    Another relevant document is the "Software Configuration Management (SCM)
    Tool Evaluation" from Micro Systems, Inc.
    (http://www.cmcrossroads.com/ubbthreads/download.php?Number=52408). It
    describes the limitations of VSS and presents an evaluation of several
    alternatives. ClearCase was the best alternative according to the
    evaluation criteria.

    VSS is a very limited tool. I've even seen claims that some Microsoft
    projects use other tools (particularly Perforce) instead of it. It is
    not surprising that ClearCase does better in the marketplace.

    It's less clear why ClearCase does better than cheaper tools like
    Perforce, BitKeeper, and AccuRev that seem to have significant
    advantages over it in some areas. The one obvious major advantage of
    ClearCase over the competition is dynamic views. Specific benefits
    include rapid workspace creation, easy workspace sharing, simplified
    build configurations through automatic tracking of build dependencies
    (clearmake/omake), improved build performance through parallellization
    and automatic sharing of build products, and automatic generation of
    bills of materials for builds.
