Abstract

Many computer systems that automatically control financial applications are required to handle large amounts of data with timing constraints imposed on the data and on the transactions that access the data. Traditional database technology, however, is not designed to manage perishable (timeconstrained) data of financial applications, such as “current” stock prices and trading volumes in index arbitrage transactions. Furthermore, traditional database systems are not capable of scheduling the time-constrained transactions in financial applications, such as transactions that must be performed within time bounds of guaranteed price quotations. This paper presents a schema model of real-time objectoriented database that addresses these weaknesses and shows how this model can support a form of intelligent program stock trading called index arbitrage. This paper also illustrates the use of a protocol called timed atomic commitment, which is an extension of traditional distributed database atomic commitment protocol, to perform index arbitrage transactions using our real-time object-oriented database model.
