Abstract:
1. An information processing system comprising: a first application apparatus for managing, a first data item recorded in a predetermined format and stored in a storage apparatus coupled to the first application apparatus; a second application apparatus for managing, a second data item, which is different from the first data item, recorded in a format other than the format of the first data item and stored in the storage apparatus; a server device for managing the first application apparatus and the second application apparatus by a list of application apparatus, for accessing the first data item and the second data item via the first application apparatus and the second application apparatus, and for managing access to the first data item and the second data item in a unified access format; and a client device for accessing the server device and using the first data item and the second data item provided in the unified access format by the server device, wherein the server device allocates a unique identifier to each of the first data item and the second data item, manages, using data management information, a correspondence between each identifier and each access method for accessing the first data item and the second data item identified by that identifier, an original storage location of the first data item and the second data item, and an updated data storage location of the first data item and the second data item, wherein the server device converts unique data information relating to each of the first data item and the second data item to the unified access format, and unique command information relating to each of the first data item and the second data item to the unified access format, wherein when the server device receives a read request specified by the unique identifier of the first data item from the client device, the server device specifies the first data item by the unique identifier based on the data management information, reads the first data item stored in the storage apparatus via the first application apparatus by using a unique command for read data corresponding to the first application apparatus, converts the first data item read from the storage apparatus to the unified access format, and sends the converted first data item to the client device.
