    摘要: In a cache memory management device, a time measuring unit measures a time period required to obtain data from a database. The data obtained from the database is linked to the time information and both are stored in a data cache unit. If the data cache does not have sufficient room to store the data obtained from the database, a data replacement determination is made. In one embodiment, the data is replaced by referring to the total data access time. In a second embodiment, if a statistics processing unit judges that the access time and the size of each data are proportional to each other, then cache data is replaced by referring to the size information from a size calculation unit. If, however, the statistics processing unit judges that the access time and the size of each data are not proportional to each other, cache data is replaced by referring to the time information from the time measuring unit.

    摘要: The present invention provides an electronic document filing system. The electronic document filing system comprises a document database for storing document, an input unit for controlling the system, a document data generating unit for generating the document data, a layout data generating unit for generating layout data, a display unit for displaying the data generated by the document data generating unit and layout data generating unit, and a control unit for controlling the display unit to send image data of the page being retrieved to the layout data generating unit upon receipt of a retrieval command from the input unit to display the resulting data of a conversion into the layout data, and to send the image data of the specified page to the document data generating unit to display the image data of the specified page in a legible image.
