| Abstract(in English) | To provide a virtual work environment for cooperative work support, the VWDB is designed and implemented based on the network virtual reality system architecture. The VWDB is different from the traditional network virtual reality system in that it supports a full-scale database function, i.e. not only queries but also update requests are accepted. In order to realize the database function in the VWDB, the VWDB transactions are introduced. It is shown that the VWDB transactions are different from the traditional transactions in that the VWDB continuous transactions need to relax both the transaction model and the ACID property of transactions. Since the VWDB integrates a number of front-end virtual reality systems and a back-end database system via a high-speed network, a novel synchronization mechanism to make the state of the virtual world of the VWDB clients and the state of the back-end database system consistent is also investigated based on the transaction concept. |
