In enterprise computing, clustering is a useful architecture because most companies have a need for high-availability, high-performance and stabilized load-balanced computing power. However, when we use clustering architecture, we must consider a data control method. Representative of the two methods of data control are centralization and distribution. In this paper, we will propose the hybrid method and we will introduce our system implementing the stock trading system method of Meritz Securities. Our system has three hierarchical layers and is operated with some special method we called the HDA. This HDA method has some useful factors for our data control method.
