An Adaptive Database Design Approach for Biosignal Data Storage and Retrieval

Abstract

In the traditional scenario of database usage, database usually plays a passive role as a backend for supporting user applications. This introduces a tight coupling from database to user applications, which is the source of high maintenance fee for the database, especially for databases developed using conventional normalizationbased design approach. In the case of designing a database for biosignal data storage and retrieval, uncertainties both from the data provider and the data consumer make an even stricter situation for database design. This paper addresses the issues concerned with an adaptive database design approach capable of producing a survivable database design in facing the changing environment of biosignal domain, and presents two showcases with databases designed following our adaptive database design approach.
