碩士 === 中國文化大學 === 資訊管理研究所 === 96 === In recent years, huge amounts of data appeared on the internet. Some of these are frequently changed and necessary for decision making such as stock information, raw material information, etc. A decision making (or support) system uses these kinds of data needs to retrieve these data from internet in rational time interval. This research presents a system model based on grid technology to solve this problem using existing equipments. The model can not only retrieve huge amounts of data by using many PCs in a satisfactory time period, but can aggregates processing powers of many computers into a virtual super computer to finish job easily which is impossible to be done for a single PC. The implementation in this research proved that about 70% of time saved between the model used and a single-computer mode. Beside, this model combined several different mechanisms like dynamic job scheduling, data backup, data integrity check, …, etc. To ensure the system model more robust.
