In this paper, a locking-based concurrency control scheme is presented for object-oriented databases (OODBs). It is designed for controlling accesses to class hierarchies, which is an important concept in OODBs. Based on access frequency of each class, the proposed scheme incurs less locking overhead than the existing works, explicit locking and implicit locking, for any OODB environments. This paper also proves that the proposed scheme performs better than the existing schemes.
