| With the rapid development of the Information Technology, business data are more frequently utilized by corporations and organizations for the purposes of management and decision-making. Many research works have been devoted to the implementation of efficient information processing and sharing. A representative technology is information distribution, which not only provides exact and fast services on information searching, transmitting and releasing, but also helps improving the ability of cooperation among teems, departments, and even organizations.There are many substantial requirements of an Information Distribution System (IDS). One is the network architecture. This thesis focuses on the Grid, which provides high speed and secure networks for heterogeneous platforms. The Grid integrates distributed resources, including hosts, databases, software, etc. to provide various services in the process of information distribution. To make the distribution process more intelligent, we make use of Knowledge Discovery in Databases (KDD) technologies, particularly Rough Sets.In theory aspect, this thesis shows the Grid and P2P integrated IDS's requirements and solutions. The IDS provides the function for information delivering, load balance and copies management by Grid and P2P way. Even use the Virtual Organization (VO), one of the important concepts in Grid, to divide the users and information data into different groups. IDS use the rules to create the relationship between User VO and Data VO. Rough set theory and its algorithms can generate rules for KDD and rules study. In the GUI designing and developing progress, use some cutting-edge technology to make more safely, more friendly and lower cost in network transmitting.In realizing aspect, this thesis explains the difficulties and solutions in developing IDS. According to the Grid and P2P based IDS's requirements, it refers the virtual organization concepts in Grid to divide the materials and attributes reduction algorithms in rough set theory to study the system rules.By the studying and developing of IDS, the methods of this thesis can improve the efficiency of information sharing, accuracy and automaticity and the robustness of information distribution network gets improving as the test result. |
