Abstract

The performance of flow graph locking (FGL) is compared with that of two-phase locking (2PL). As the data sharing level increases, FGL has a better response time than 2PL. Regardless of the data sharing or multiprogramming levels, FGL usually facilitates a better throughput rate than 2PL.
