A Multidatabase System for Tracking and Retrieval of Financial Data

Abstract

We have built a multidatabase system to sup-port a financial application that stores histor-ical data used by traders to identify trends in the market. The application has an up-date rate (append-only) of 500 inserts per sec-ond and also has sub-second response require-ments for queries. A typical query requests between 100-1000 records. In this paper we define the characteristics of the application, the multidatabase system we used to support the applications and the extensions we made in t.he application to achieve the required func-tionality and performance. 1
