Abstract

Time-critical industrial applications represent a database requirement
profile which is significantly different from that in traditional
(business) database applications. Results of a corresponding needs
survey performed among leading developers of factory systems are
presented in the paper. The requirements have paved way to the
development of the RAPID systemÐ-a fast-response and active history
database Client/Server system which has a unique assortment of
temporal and active characteristics. Some of the most crucial design
questions are discussed, including the choice of the process
architecture and concurrency models, the temporal table model and the
triggers semantics.
