Abstract: An information processing system includes a first server that performs processes in accordance with first operations included in a system of operations for the first server, a second server that performs processes in accordance with second operations included in a system of operations for the second server different from the system of operations for the first server, and a terminal apparatus that requires the first and second servers to perform the processes. The terminal apparatus includes a first requiring portion that requires the first server to perform a process in accordance with at least one of the first operations designated by a user and a converter that converts the at least one first operation into a command set and stores the command set in a storage, the command set including at least one command, which is a part of the process and is performed by the first and second servers.

Abstract: A computer readable medium stores a data management program that manages data, provides the data to a client connected over a network, and is capable of performing communications in accordance with a plurality of types of protocols, the data management program causing a computer to execute a process for the data management, the process comprising managing an access right to the data; managing basic policy information concerning a protocol used for providing the data to the client; managing protocol information that sets, for each protocol, data capable of using the protocol as a protocol used for providing the data; analyzing an environment of the client when a data request from the client is received; and determining a protocol used for providing the requested data according to the analyzed client environment, the access right, the basic policy information and the protocol information.

Abstract: A computer readable medium storing a program that causes a computer to execute information processing is provided, wherein plural pieces of management object information are stored in a storage device with unique identification information and non-unique name information, the information processing including: receiving a process request that specifies management object information of a process object by using location information which is represented by a sequence of name information assigned to respective pieces of management object information; selecting one piece of management object information corresponding to the location information with reference to history information which is registered with the location information and the management object information being associated with each other; and sending back a result of a process that is executed for the selected management object information of the process object in accordance with the process request.

Abstract: A data management system having a plurality of data servers connected via a network is provided, wherein each data server includes: a data management section that manages a data item in correspondence to a local identifier of the data item and a global identifier of the data item; a request processor section that searches the data management section for a data item requested from a client, provides the requested data item to the client when the requested data item is found, and transmits a data inquiry containing a global identifier of the requested data item to other data server to detect a data server which stores the requested data item when the requested data item is not found; and a response section that searches, when receiving a data inquiry from another data server, the data management section for a data item corresponding to a global identifier contained in the data inquiry and transmits a result of the search to the another data server.

Abstract: In a data management system in which a data server cooperates with other data servers connected thereto via a network, each data server has a data management section in which one or more data items are stored in correspondence to globally unique data identifiers, a request processor section that searches the data management section for data item requested from a client, provides the requested data item to the client when the requested data item is found, and transmits a data inquiry to other data server on the network to detect a data server storing the requested data item when the requested data item is not found; and a response section that searches, when receiving a data inquiry transmitted from another data server, the data management section for the requested data item and transmits to the another data server a result of the search.
