Differences between UCM and base ClearCase

Base ClearCase® consists of a set of powerful tools to establish an environment in which developers can work in parallel on a shared set of files, and project managers can define policies that govern how developers work together.

UCM is one recommended method of using DevOps Code ClearCase for version control and configuration management. UCM is layered on base ClearCase. Therefore, it is possible to work efficiently in UCM without having to master the details of base ClearCase.

UCM offers the convenience of an out-of-the-box solution; base ClearCase offers the flexibility to implement virtually any configuration management solution that you deem appropriate for your environment.
