Process database support system is one of the key technologies for green manufacturing implementation. In this paper, the process database support system for green manufacturing was developed with Browse/Server (B/S) three level structure on the basis of Web, which has the function of distributed processing and storage of the data. The composing and its green characteristics were discussed in detail respectively. Furthermore, the key develop technology of the database system, such as network requirement, assistant planning and green assessment of process and the accessing to the database were analyzed. A case study was performed to illustrate and examine the validity of the database system.
