Distributed Database Searching System based on Alchemi

With the information expanding and network popularization, the way that accessing single database can not satisfy the demands for users. The requirement to access distributed database is increased. This paper firstly implemented distributed database query with the grid computing architecture Alchemi which is based on .NET. Then, a distributed database searching system model was constructed by grid computing technology, while the architecture and the operation process of the model were described in detail. Finally, the model was achieved with the platform of Microsoft.NET. According to the analyses of the configuration information and experimental results, it is proved that, compared with the current distributed database searching system, the system that developed by Alchemi is not only easy to configure, but also able to assure the efficiency and accuracy of the query.
