SEMANTIC CONCURRENCY CONTROL

概要

論文の詳細を見る
In database systems and distributed database systems, multiple transactions access the same objects. In order to keep the databases and distributed databases consistent in the presence of multiple transactions, the concurrency controls are required. There are two approaches. In the first approach, based on the object concept, the permutation relations on the objects among higher level operations, e. g. deposit and withdrawal on the accounts, than read and write operations are semantically given [LYNC]. In the second approach, based on the semantics of the transactions, a set of transactions which can be executed concurrently is defined [GARC]. In this paper, we take the second approach.
