The controlled-generator model of P.J. Ramadge and W.M. Wonham (1988) is used to formulate the concurrent execution of transactions in database systems as a control problem for a partially observed discrete-event dynamical system. The control objectives of this problem (for concurrency control and recovery) and the properties of some important transaction scheduling techniques are characterized in terms of the language generated by the controlled process and in terms of the stage of an ideal complete-information scheduler. Results about the performance of these techniques are presented
