We propose a concept of "Numerical Information Environment (NIE, hereafter)" and its actual method of system constitution. The NIE has been studied and developed to store, analyze and simulate a large scaled numerical data and information of a target (natural phenomena or an artificial structure) interactively and iteratively. First, a global concept of "Numerical Information", and "Numerical Information World" are defined. To establish and operate the NIE, a concept of "Software Bus (I, II, III)" and its actual programming method have been developed on the basis of the World. The Software Bus system always plays the role of a distributing center of all the numerical data and information, and is also a general method to transmit them among the modules in the NIE and between the processes in the UNIX. By using the software bus system, any kinds of direct numerical simulation or analyses programs can be mounted on the software "Bus" system. One more feature is that any modules in the NIE can directly be used in the user's program system without any modifications of source programs. Therefore, the system make-up is rapidly performed and operation of the NIE is flexible. To get a "view" of this database oriented system, a "Bus View" system has been developed with the aid of a graphic system. We especially describe an application system named "Dynamic DB System". We can conclude that the NlE is suitable for drawing various interesting and valuable knowledge or view of the user's "target".
