Provided is a power management system capable of controlling charge and discharge of storage batteries according to power requirement of load even when handling electric power of large scale. A system controller receives load-related information data including the power requirement of load and storage battery-related information data including a state of a storage battery assembly including multiple storage batteries and creates an overall charge-discharge control instruction for the entire power management system based on the load-related information data and the storage battery-related information data. A hierarchical charge-discharge control apparatus receives the overall charge-discharge control instruction from the system controller and performs charge-discharge control of the multiple storage batteries, classified into hierarchical levels, on a hierarchical level basis.

A network device included in a local area network is controlled with an outside telephone. A telephone line is directly connected to a router incorporated in a local area network including a computer . A server is connected to the telephone line , and the telephone line is also used as the Internet . The outside telephone makes a call to the router through the telephone line while the router detects the phone call to send a packet for activation to the computer to activate the device in the wait state. The computer after the activation requests the server to allow its connection to the Internet , obtains a network address in the Internet , and notifies the network address to the outside telephone . Thereafter, data is exchanged between the telephone and the computer

Data monitoring means adds tag information representing a document conversion method to hyperlink information included in a hypertext type document sent to a user-side device from a server-side application, and sends to the user-side application the hyperlink information to which the tag information is added. When the tag information representing the document conversion method is included in a command to request retrieval which is sent from the user-side application, the data monitoring means converts the document sent from the server-side application as the results of the retrieval in accordance with the document conversion method represented by the tag information and sends the converted document to the user-side application.

A file management apparatus includes a file storage portion and a manipulation portion. The file storage portion stores a plurality of files therein. Each file includes one or more data structures. Each data structure includes one or more elements. The file storage portion further identifies each file with a file identifier and identifies each data structure within the file with an internal identifier and with the number of data structures contained in the file. The position of each data element and the number of data elements within a data structure are also identified. The manipulation portion manipulates the structure of the data stored in the file storage portion by employing the file identifier, the data structure identifier, and element position.

File management apparatus permitting access to portions of a file by

A program developing system includes a plurality of graphic editors representing specification definition information a user inputs in representation formats different from each other and a mutual conversion unit for converting specification definition which the user described with a graphic editor into a representation format of another graphic editor. The mutual conversion unit activates another graphic editor to allow input of specification definition by the converted representation format. The graphic editors can hierarchically represent specifications and allows specification description at an arbitrary level. The program developing system includes a parts management unit for registering description of semantically completed specification definition as parts and an execution unit for extracting executable program structure from the specification definition information represented by graphic editors and producing an executable program The executable program reserves the hierarchical structure in the specification description by the user. The execution unit executes a program at an arbitrary level and shows the execution results to the user. By execution and verification of the program at an arbitrary level, the user can know whether a program satisfying the specification is produced or not at a sub program level, which improves the program developing efficiency.

Program developing system allowing a specification definition to be

An apparatus for manipulating a relational data base includes a unit for describing input data in a table format, a unit for describing all the operational manipulation with respect to the input data in a non-text format, and a unit for outputting data by referring to the relational data base based on the described input data and operational manipulation. The input data of a table format includes an input table and an output table. The input table includes an operational description region and the output table includes a region wherein a map relation between the respective items of the input and output table is described. The manipulation contents are described in the operation manipulation description region and the map relation description region. The operation flow is described and defined by a connection line with directiveness. The apparatus enables description of all the operational manipulation in a graphical manner in a non-text format, providing a user with data base manipulation environment with excellent understandability and operability.
