In this dissertation a new concurrency control algorithm is proposed and compared for efficiency with two of the existing algorithms. An abstract model is used to evaluate the costs associated with the algorithms and performances of the algorithms are determined using simulation technique. Simulation results show that none of the algorithms is uniformly better than the others. However, the newly proposed algorithm, the Integrated Transaction Characteristics, is generally better when concurrency control information is kept in primary memory.
