Abstract

Information consisting of a plurality of pieces of data can be reproduced in the same state it was browsed previously. On receiving a data acquisition request from a data use unit, a request analysis unit analyzes whether the data acquisition request is a data relay request or a history information acquisition request. As a result of the analysis, if the data acquisition request is a history information acquisition request, the request analysis unit extracts a data name, time, and a search method from the data acquisition request. If the data acquisition request is a history information acquisition request, a history management unit uses a data name and time extracted by the request analysis unit to search a history memory for appropriate history information by a search method extracted by the request analysis unit and outputs data contained in the detected history information.
