METHOD, SYSTEM AND PROGRAM FOR VERSION MANAGEMENT OF SHARED FILE, AND RECORDING MEDIUM FOR RECORDING VERSION MANAGEMENT PROGRAM OF SHARED FILE

摘要

PROBLEM TO BE SOLVED: To provide a version management system of a shared file capable of handling any kind of file, dispensing with naming of a file in each version by a user, and capable of clarifying parentage between each version. SOLUTION: The shared file which is an object for version management has a logical file path which is common even when a version is changed, and an actual file path which is different in each version. When the user writes a file in the logical file path, a new version number is imparted. The actual file path is generated uniquely from the logical file path and the version number. The entity of the file is retained in the actual file path. The user can read a specific version of the shared file by designating the logical file path and the version number.
