The new generation leveler control system need to deal with amounts of data. Directed at the characteristics, this article demonstrates the structure design of its database architecture. From the communication interface, hardware and software environment, functions, technologies, etc., we expounded the implementation of database system, such as real-time database, alarm database, model material databases, historical database, and safety information database and so on. It shows that the database system is a core of new generation leveler control system. We also present specific examples of design and give the detailed method of approach.
