This paper presents the design and implementation of a deductive database system. RDL1, is the production rule language for this system. This language is an extension of logic based languages towards the support of updates and complex domains. Different features of this language are described with its applications. The general architecture of the system is presented highlighting integration with a relational database system. Then, three original features of the system are discussed: extensibility through the definition of end user data types, query optimization techniques, and the extensibility of the control strategy. Future improvements and extensions conclude the paper.
