Rational ClearCase

Version control

• Rational ClearCase manages and controls source code, libraries, documentation, binaries, web artifacts, and nearly any project artifact that can be represented as digital content.
• Rational ClearCase also controls versioning for directories, subdirectories, and all file system objects.
• Advanced functions allow you to delete previous versions, create and delete branches, list version histories, and compare and merge versions.

Defect tracking

• Rational ClearCase and Rational ClearQuest let you define and manage changes to software assets as activities, which is known as activity-based change management.
• File versions in Rational ClearCase are grouped into logical activities and associated with change requests in Rational ClearQuest, allowing you to manage your work at the task level, instead of managing individual files.

Parallel development

• Automatic file-branching functionality isolates specific changes or versions, allowing multiple developers on the same and different teams to work independently from the same code base.
• Merging and differencing capabilities accept uncontested changes and highlight conflicting changes for resolution.

Security

• Access control helps ensure that only authorized individuals make changes; user authentication is performed through operating system authentication mechanisms or through industry-standard Lightweight Directory Access Protocol (LDAP).
• Support for user-based and group-based permissions limits access to files and directories.
• User-based locks are available on Rational ClearCase objects, including branches, labels, elements, and metadata.
• Rational ClearCase allows programmatic authorization based on the action being performed.

Build auditing

• To assist with your governance efforts, Rational ClearCase provides build auditing.
• Rational ClearCase can generate a detailed software bill of materials, which can be used to automatically determine when built objects can be reused or shared by developers using multiple views.
• You can integrate Rational ClearCase with IBM Rational Build Forge to automate your build and release management process.
