Abstract: The current version of Simbad has been running since 1990. It was designed for command line queries and evolved to client/server mode. At the same time, its contents increased from 700,000 objects to more than 3,000,000, and the number of queries exploded from a few hundred to an average of 15,000 daily. Fifteen years later, it was time to design a new version taking into account the evolution of technologies in languages, DBMS, networking, and software architecture. This paper presents the architectural design of the new Simbad system. The choices made are analyzed and justified. The integration of SIMBAD 4 in the Virtual Observatory functionalities is also presented.
