A real-time database system (RTDBS) is designed to provide timely
response to the transactions of data-intensive applications. Each
transaction processed in an RTDBS is associated with a timing constraint
in the form of a deadline. Efficient transaction-scheduling
algorithms are required to minimize the number of missed transaction
deadlines. In thls paper a performance evaluation model is
provided to enable distributed RTDBS designers to analyze transaction
scheduling algorithms. The model is developed progressing from
a simple mathematical analysis to complicated simulations. The performance
is expressed in terms of the fraction of satisfied transaction
deadlines. The paper also provides an example simulation experiment
implemented using the model presented.
