SOURCEBANK/VM

The architecture of SOURCEBANK/VM is centered around the management of CMS files within a z/VM environment. The main components include the command processor, the file storage manager, and the user authentication module. The command processor handles user input and executes commands such as CHECKIN, CHECKOUT, UPDATE, and HISTORY.

The file storage manager is responsible for storing and retrieving file versions within the CMS file system. The user authentication module integrates with the z/VM security features to authenticate users. Communication between these components is primarily handled through CMS services.

The system uses a configuration file to store settings such as user permissions and file storage locations. The access control model is based on ACLs, allowing administrators to define granular permissions. The system provides detailed logging of all file operations, which is stored in log files for auditing purposes.

The system does not encrypt data at rest, relying on the z/VM system for underlying security. Compared to other version control systems, SOURCEBANK/VM is specifically designed for the z/VM environment, offering seamless integration with CMS file management and z/VM security features.
