Snapshot Views and Dynamic Views

ClearCase includes two kinds of views:

• Snapshot views, which copy files from data repositories called VOBs (versioned object bases) to your computer.

• Dynamic views, which use the ClearCase multiversion file system (MVFS) to provide immediate, transparent access to the data in VOBs. (Dynamic views may not be available on all platforms. For more information, see ClearCase online help.)
