Abstract: A server registers and manages program sources, functional modules of a plurality of applications and executable applications that a plurality of providers have provided and/or created. When a user creates an application, the server automatically creates an application that satisfies a condition that a user requests with a simple selecting or inputting operation. A unique ID is embedded in the created application. As a result, the user can be accurately and easily identified. While the server is creating an application, the server automatically creates a program corresponding to an access to the server. As a result, a service for which a user accesses to the server with an application is provided and operated.
