Abstract
Most of the work in real-time databases (RTDBs) [1, 14] has focused on the design and implementation of database management systems, while relatively little attention has been given to the special problems that arise in the design of database schemas to support a given set of real-time database applications. In this paper, we identify a class of real-time applications called OLFP for On-Line Fetch Processing. OLFP applications arise in telecommunications, automated control systems, on-line financial transactions, and many embedded database applications with read transactions that require real-time response. We propose a new data organization, called FIDO for Fetch-Intensive Data Organization, that is specifically tailored to meet the requirements of OLFP applications while maintaining sound software engineering principles.
