ABSTRACT

In this thesis, we propose a concurrency control scheme which schedules global transactions in multidatabase systems. Unlike other scheme which commit global transactions as soon as they have finished their execution, this scheme has attempted to delay them if their exist another global transactions that should be preceeded. Owing to the deferred commitment, the number of global restarts could be greatly reduced. This scheme‘s performance gain increased through simulations in case more than one LDBS employ timestamp ordering(TO) as a local concurrency control scheme.
