DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction and operation of an embodiment of the present invention will be described below in detail with reference to the drawings. (1) Configuration of Embodiment FIG. 1 is a block diagram showing a functional configuration of a data list display device as an example of an embodiment of the present invention. 1, the data list display device 100 includes a control unit 110, a display attribute setting unit 120, a display order setting unit 130, a consistency check unit 140, a list display unit 150, a data storage unit 160, and a data attribute storage unit 170. It is configured. Control unit 1
When displaying a list of files in the data storage unit 160, the control unit 10 controls the setting of the data attribute of the display order, the designation of the order for a specific file, and the entire process up to the actual display of the list. The data storage unit 160 includes a content group that holds actual contents (data such as text, images, audio, and the like) and a file management table that manages a group of contents as a file. The file management table includes a file identifier (file ID) for managing each file, a file name, bibliographic items common to each file (registration date, registrant name, update date, file format (for example, text information, image information, Information, audio information, etc.), size, etc., memos, etc.), data attribute ID, and data item list (FIG. 2,
(See FIG. 3). Here, the data attribute ID is a unique name for identifying the data attribute name registered in the data attribute storage unit 170, and the data item list contains the actual data value corresponding to the data item indicated by the data attribute ID. Hold.
The data attribute storage unit 170 defines data items other than bibliographic items common to each file, and is identified by a data attribute ID (see FIGS. 4 and 5). That is, each file has a variable data item defined here in addition to the bibliographic item, and this data item corresponds to that of the data storage unit 160. This variable data item
A flag indicating whether to use this variable data item, a data type of this data item (character type, character string type, date type, numeric type, logical type, etc.) and a name of this data item (See FIG. 4). Display attribute setting unit 120
Adds a “display order” which is a data item for specifying a file to be prioritized when creating a list of data held in the data storage unit 160 to a data attribute designated by a user, The data attribute storage unit 170 is updated. For example, referring to FIG. 5, an item name “display order” is added to a data item 1 having a data attribute name “abc”. In this figure, each data attribute is added to the beginning, but may be the last as long as it can be identified.

The display order is an order number appearing in the data list, and its data type is an order type. The display order setting unit 130 sets the display order when displaying the data storage unit 160 in a list. First, the user selects a file whose display order is to be set from the data storage unit 160,
The display order setting unit 130 is activated via the control unit 110. The user sets the display attribute setting unit 1 for this file.
Numerical values are input from an input device such as a keyboard in accordance with the “data type” of the data item “display order” set in 20. The input numerical value is set as the data value of the “display order” of the specified file in the file management table of the data storage unit 160, and updates the file management table of the data storage unit 160. For example, when the display order is desired to be the first, “1” is set as the data value of the data item “display order”. Also, at this time,
The consistency check unit 140 is operated to check whether there is the same sequence number (the details will be described later). When the data attribute having the data item “display order” is registered in the data attribute storage unit 170, the consistency checking unit 140 determines that there is no inconsistency in the display order specified by the user for the file having the data attribute. Check if This inconsistency means whether the same number exists. For example, if the data storage unit 160 has a hierarchical structure of folders or the like, the same number is assigned to the sequential numbers of the files belonging to the same hierarchy. Find out if there is. Thus, if the files are in different folders, the user may assign the same sequence number, and copying or moving those files to the same folder will cause inconsistencies.

[0008] When a contradiction is detected, there are the following three measures. Display the inconsistent file on the display or the like to notify the user, and change the sequence number of any file. Check the changed sequence numbers for inconsistencies,
Repeat until there is no contradiction. When the file is started from the display order setting unit 130, the sequence number of the previous file to which the same number has been set is shifted backward by one, and the sequence number specified now is prioritized. The shifted numbers are checked for inconsistencies and sent forward sequentially. Similarly, when the file is started from the display order setting unit 130, the sequence number of the previous file to which the same number has been set is not set, and the sequence number of the currently designated file is set. The list display unit 150 stores the data storage unit 160 based on an instruction from a user or an application program.
Is created, and the result is output to an output device such as a display or a printer. This data list is
Where a value is set in the data item "display order" of the file management table of the data storage unit 160, the order is determined as follows. For files for which the sequence numbers are not set, the files are sorted by key data for displaying the list. With respect to this sort result, the result of inserting the file into the order number of the file whose order is designated is the result of the list display. With the configuration as in this embodiment, the following effects can be achieved. When a list of names of a plurality of data is displayed in a list, by specifying a position to be displayed at a position convenient for the user, it is possible to efficiently find specific data from the list. -Even if the user specifies the order of inconsistency, it is possible to prevent inconsistency when displaying the list.

(2) Display attribute setting operation FIG. 6 is a flowchart for explaining the flow of the display attribute setting. First, the user selects from the data attribute storage unit 170 a data attribute to which a display attribute, which is a data item for specifying a file to be prioritized when creating a list of data held in the data storage unit 160, is added. , An instruction to set display attributes is input (step S10).
0). In response to this instruction, the data attribute and data type of “display order” are added to the data attribute specified by the user, and the data attribute storage unit 170 is updated (step S1).
10). This addition may be at the beginning or end of the data attribute as long as it can be identified. The data value corresponding to the added data item “display order” is set to “not set” for the data having the data attribute specified by the user in the data attribute storage unit 170, and the file in the data storage unit 160 is set. The management table is updated (Step S120).

(3) Display Order Setting Operation FIG. 7 is a flowchart for explaining the flow of display order setting. First, the user selects a file whose display order is desired to be set from the data storage unit 160, and instructs this display order setting (step S200). The user inputs a numerical value from an input device such as a keyboard in accordance with the "data type" of the data item "display order" in which the display attribute is set for this file (step S210). It is checked whether or not the sequence number of the input numerical value already exists in the data storage unit 160 (step S220). If it already exists, the numerical value is corrected by one of the following methods (which method is set in advance). Shift the sequence number of the previous file to which the same number has been set by one backward, and give priority to the sequence number specified now. The shifted numbers are checked for inconsistencies and sent forward sequentially. Similarly, the sequence number of the previous file to which the same number has been set is not set, and the sequence number of the file specified now is set. -Display the overlapping state and have the user correct it. Check this input number again. The input numerical value is set as the data value of the “display order” of the specified file in the file management table of the data storage unit 160, and updates the file management table of the data storage unit 160 (step S230).

(4) Operation of Consistency Check in Display Order FIG. 8 is a flowchart for explaining the flow of the consistency check in display order. It is checked whether or not there is a data attribute in which the data item “display order” is registered in the data attribute storage unit 170 (step S300). If there is no data attribute, the process ends. If there is, the file in the same folder having the data attribute is checked to see if there is any inconsistency (the same number exists) in the display order specified by the user (step S310). In this inspection, it is determined whether or not there is a contradiction / duplication (step S320). If there is a contradiction, it is corrected by one of the following methods (this method is set in advance) (step S330). Display the inconsistent file on the display or the like to notify the user, and change the sequence number of any file. Check the changed sequence numbers for inconsistencies,
Repeat until there is no contradiction. Shift the sequence number of the previous file to which the same number has been set by one backward, and give priority to the sequence number specified now. The shifted numbers are checked for inconsistencies and sent forward sequentially. -The sequence number of the previous file for which the same number has been set is not set, and the sequence number of the file specified now is set. It is checked whether there is a file to be checked in the same folder (step S340). If there is still a file, the process returns to step S310 and the check is repeated. If there are no more files to be inspected in the same folder, the process returns to step 310 and the inspection is repeated for files in other folders having the same data attribute (step S350). When the inspection is completed for one data attribute, step 300 is executed for another data attribute.
Return to and repeat the inspection.
