| Distributed product knowledge-base system is an important project in the field of computer and its' application. It is very important to study the distributed product knowledge database system for enhancing the enterprise's information level, production efficiency, and the ability of market competition.Distributed product knowledge-base system (DBKS) are studied for sharing enterprise's information. DBKS can settle the problems which the communication of the scatter system, and it has the trait of load balance, high reliability and easy to expand. The establishment of DBKS makes the enterprise easy to exchange information. The traditional database system can not meet the needs of the development of enterprise.It's important to establish a low cost, high efficiency, high reliable knowledge model. On the base of distributed database, we finish the data access by the ADO.Net, and provide the Data Convert service by the Web Services. On the base of this model, Data search, consistency and data conflict of the distributed database are studied. And an adapter model is provided for data exchange in different enterprises.1. Using One-Master Multi-Slave mode to solve the data conflict;2. Using Two Stage Submit or Copy Server to ensure the data's consistency;3. Using adjustor to achieve the integration of Heterogeneous Distributed Database;4. Using Data Adapter to achieve the data's query and switch;According to the study results, we designed an enterprise information sharing model, at last, the paper prospected the foreground of the distributed product knowledge database system. |
