Abstract: A contents retrieval system has: retrieval request receiving means for receiving a retrieval request of contents on a communication network from a user accessing through the communication network, and setting up processing conditions for retrieval processing in accordance with the retrieval request, and further issuing a reservation number of the retrieval processing and informing the user of the reservation number, and in addition applying the reservation number to the processing conditions and registering the same with a predetermined retrieval management table; contents retrieval means for retrieving the contents on the communication network in accordance with the processing conditions registered with said retrieval management table and storing the retrieval result, together with the reservation number, in a predetermined retrieval result storage file; and retrieval result providing means for retrieving a retrieval result associated with the reservation number from among the retrieval results stored in sai

Abstract: A process control system for controlling processes has a work flow display for displaying on a screen a work flow in which a plurality of processes constituting a work is represented in form of a diagram. The work flow display displays on the screen the work flow in which a plurality of process display units each represented by the diagram consisting of a process area representative of a process, an input area representative of a processing object in the process and an output area representative of a processing result in the process, is coupled over a plurality of stages in a sequence that a work is formed.

Abstract: In an image data providing apparatus, when a retrieval server receives a request of a supply for image data from a client, the retrieval server requests of the client utilization information representative of a utilization form estimated on an image represented by the image data required by the request in exchange for a supply for image data. And when the retrieval server receives the requested utilization information from the client, the retrieval server provides image data.
