PROBLEM TO BE SOLVED: To make it possible to easily execute a change such as the addition of a database without changing an application by providing the system with many container servers for managing databases and one or more branch servers for setting up a branch from an application server having received a request from a client to the container server managing data. SOLUTION: An application server AP receiving a request from one of plural clients 1 to 4 informs a branch server 1 of the request. At the time of receiving the request from the server AP, the server 1 discriminates the request data and forms a branch route. Even in the case of adding a container server 9 for managing a database 9 shown by a dotted line, e.g. the addition is executed only by adding a branch condition for branching from a branch server 2 to the container server 9, so that the rewriting of the reception application is quite unnecessary.
