EIT - Escalonador Inteligente de Transações

Maristela HolandaAngelo BraynerSergio Fialho

Serializability has been used as a criterion to correctly synchronize the execution of concurrent operations belonging to several transactions. For that reason, concurrency control protocols should yield schedules using serializability. Concurrency control protocols may present an aggressive or conservative behavior. This paper presents the Transaction Intelligent Scheduler (EIT), which has the ability to synchronize database operations by using concurrency protocols with an aggressive or conservative behavior. EIT adapts its behavior dynamically according to characteristics of the computing environment where it is inserted. In order to make such changes, an expert system based on fuzzy logic is one of the components of this scheduler.
