A component base technology can maintain effectively and save time and expenses of development. In this thesis we found many components including the setup/execution component to construct game sites and analyzed and designed the components by the use of UML. If programmers develop the game site by using the component that distributes, setups and executes the game program by one click and other components, they can manage the game site easily, distribute the game program effectively and offer a convenient user interface. Also, by the reuse of these components, programmers can construct the game site easily and economically.
