Intelligent, optimistic concurrency database access scheme

摘要: Methods for minimizing conflicts in an optimistic concurrency database access scheme are described. The method provides users or software processes with cache copies of records and tracks which data items the copy were modified whether they read, read before ever being modified. A decision is then made using this information as to current transaction can be committed database. inventive engrafts intelligence commitment process accommodates many transactions prior art schemes consider conflicting. Consequently, increases throughput such systems.
