This paper describes TAXIS, a language for the design of Interactive Information Systems (e.g., credit card varification, student-course registration and airline reservations). TAXIS offers (relational) database management facilities, a means of specifying semantic integrity constraints and an exception-handling mechanism, integrated into a single language through the concepts of class, property and the ISA (generalization) relationship. The paper includes a description of the main constructs of TAXIS and illustrates their usefulness with examples.
