DDS: The data delivery system

DSS is a plug-ins based data delivery system extension of the application-oriented DBMS Phasme. It is intended to be used as a high performance customizable plug-ins backend for widely varying application domains. It is designed to satisfy maximum of application requirements and information systems' needs and to get maximum database performance out of today's hardware trends. The architecture has already achieved success in supporting video processing (Andres, 1996a, 1996b) and work is well under way in a project where it is used as a hypermedia server. DSS provides an extensible layer supporting plug-ins mechanisms and employs both inter and intra-operation parallelism. In this paper, we describe how we tackled the data delivery functionality with our open system.
