Why concurrency control and recovery are necessary in a database system is then discussed. The concept of an atomic transaction and additional concepts related
Previous research has shown that timestamp management is the key scalability bottleneck in concurrency control algorithms. This pre- vents the system from
Most current approaches to concurrency control in database systems rely on locking of data objects as a control mechanism. In this paper two families of
