ABSTRACT:
The invention regards a system (10) and method for managing BLOBs. The system combines a file subsystem (20) and a database subsystem (30), wherein the database subsystem (30) comprises relations between file names of files (40) comprising a BLOB (50) and BLOB names. In the event of modification of a file (40) containing a BLOB (50), a new file, having a new file name, is created, where a relation between the new file name and the BLOB name is created within a database transaction in the database subsystem (30). By thus extending the ACID-properties of database transactions to files, it is ensured that operations on BLOBs in the system (10) meet the ACID-requirements while keeping the efficiency of operations on files.
