mobile agents for world wide web distributed Database access
IEEE Transactions on Knowledge and Data Engineering, 2000Co-Authors: Stavros Papastavrou, George Samaras, Evaggelia PitouraAbstract:The popularity of the Web as a universal access mechanism for network information has created the need for developing Web-based DBMS client/server applications. However, the current commercial applet-based approaches for Accessing Database systems offer limited flexibility, scalability, and robustness. We propose a new framework for Web-based distributed access to Database systems based on Java-based mobile agents. The framework supports lightweight, portable, and autonomous clients as well as operation on slow or expensive networks. The implementation of the framework using the aglet workbench shows that its performance is comparable to, and in some case outperforms, the current approach. In fact, in wireless and dial-up environments and for average size transactions, a client/agent/server adaptation of the framework provides a performance improvement of approximately a factor of ten. For the fixed network, the gains are about 40 percent and 30 percent, respectively. We expect our framework to perform even better when deployed using different implementation platforms as indicated by our preliminary results from an implementation based on Voyager.

Application of Distributed Component in Database Access of Unreliable Network
Computer Engineering, 2011Co-Authors: Xu GuangAbstract:According to low efficiency in network Database Accessing in unreliable military communication system,this paper proposes the Database access model based on distributed component.The clients reduces Accessing Database times through caching data,and the Database server administrates the connection with clients using distributed component,then notifies clients updating data,which can reduce the data traffic in the network.Estimational result proves that the efficiency in the application system can be improved.

Database access technology based on connection pool in jsp
Computer Engineering, 2004Co-Authors: Song ZhongshanAbstract:This paper mostly introduces the Database access technology of JDBC and the working mechanism of connection pool, and a connection pool is established,which allows many clients to access simultaneously. Besides,connection pool is used to optimize efficiency of Accessing Database in JSP.
