When several transactions execute concurrently in a database, the isolation property may no longer be preserved. It is necessary for the system to control the interaction among the concurrent transactions. This paper presents a new locking model for concurrency control in object oriented database systems.

The proposed model consists of a rich set of lock modes, hash table, lock-baseddoi:10.2481/dsj.4.59 fatcat:qb2moglqovczxhosmxpt2zswje
