IBM Rational ClearCase - History

History

ClearCase was developed by Atria Software and first released in 1992 on Unix and later on Windows. Some of the Atria developers had worked on an earlier system: DSEE (Domain Software Engineering Environment) from Apollo Computer. After Hewlett-Packard bought Apollo Computer in 1989, they left to form Atria. Atria later merged with Pure Software to form PureAtria. That firm merged with Rational Software, which was purchased by IBM in 2003. IBM continues to develop and market ClearCase.

Famous quotes containing the word history:

    Tell me of the height of the mountains of the moon, or of the diameter of space, and I may believe you, but of the secret history of the Almighty, and I shall pronounce thee mad.
    Henry David Thoreau (1817–1862)

    History is the present. That’s why every generation writes it anew. But what most people think of as history is its end product, myth.
    —E.L. (Edgar Lawrence)

    I am ashamed to see what a shallow village tale our so-called History is. How many times must we say Rome, and Paris, and Constantinople! What does Rome know of rat and lizard? What are Olympiads and Consulates to these neighboring systems of being? Nay, what food or experience or succor have they for the Esquimaux seal-hunter, or the Kanaka in his canoe, for the fisherman, the stevedore, the porter?
    Ralph Waldo Emerson (1803–1882)
