| Abstract(in English) | In order to realize a "life-size" database system, we have been designing a system that makes virtual reality system a database system. For that purpose, Masunaga proposed the Block-World Database System, which was implemented by integrating two virtual reality systems and an object-oriented database system. But, the data model of this system has a defect in that it can't truly represent real-world objects because it represents all real-world objects as blocks. To resolve this problem, we propose the "Virtual Environment Database System (VEDB)" as a revised new version of the Block-World Database System, where the real-world objects are represented in the virtual reality space as they are in the real-world. This paper reports a new data model for the VEDB particularly from the data structure point of view, an operational overview in the VEDB virtual work space, and its typical usage of constructing a virtual mail. |
