Description

  The present invention relates to a data processing apparatus having a data search function.

  In an information processing apparatus such as a computer system, various application programs are executed under the control of an OS (Operating System) to perform specific processing. The operator inputs necessary information by operating a keyboard on which numeric keys and alphabet keys are arranged in an input field such as a text box arranged on the execution screen of the application program. In addition to the direct input method using the keyboard as described above, a general method is also available in which a data inquiry screen is displayed by a specific operation, and an operator selects and inputs desired data.

  In the data input method using the inquiry screen, an initial screen of the inquiry screen is first displayed, and an input of search conditions by the operator is accepted. Next, data that matches the search condition for which the input has been accepted is searched from a predetermined data file, and the search result is displayed in a list on the inquiry screen. When the operator selects desired data from the displayed search results, the data is automatically input to the input field on the application screen.

  As an operation method of data search using such an inquiry screen, a synchronous search method and an asynchronous search method are known. The synchronous search method is an operation method in which the found data is displayed in a list on the inquiry screen after the data search for all data files is completed under the accepted search conditions. On the other hand, the asynchronous search method is an operation method in which the found data is sequentially added and displayed on the inquiry screen while searching for data under the accepted search conditions.

For example, an information search device described in Patent Document 1 is known as an information processing device having an asynchronous search method search function. The information search apparatus includes a search client and a search server, and is configured such that the search server executes a search for a character string requested by the search client and displays the progress information on the search client display. .
JP-A-6-231173

  The synchronous search method has the advantages that the program structure is simple and the application development efficiency is high because the inquiry screen is displayed after the data search is completed. However, when a large amount of data is registered in the data file, it takes a long time to search the data. Therefore, the operator waits until the data list is displayed on the inquiry screen, which is disadvantageous in terms of usability.

  On the other hand, since the asynchronous search method is displayed in order on the inquiry screen from the found data, even if a large amount of data is registered in the data file, the target data is selected and input without waiting for the end of the search process. It has the advantage of being easy to use. However, since the asynchronous search method simultaneously performs data search and display of the inquiry screen, development of an application program that adopts the method requires programming knowledge of parallel processing, and the program structure becomes complicated. For this reason, the development efficiency of the application program is inferior to that of the synchronous type.

  As described above, the synchronous search method and the asynchronous search method have contradictory advantages and disadvantages, and the search method is high in development efficiency like the synchronous search method and easy to use for the operator like the asynchronous search method. It was desired. In addition, a system in which a search server is installed like the information search device described in Patent Document 1 is a small system in which several data processing devices are LAN-connected, or a single device without LAN connection. It is too large to apply when only the data processing device is used alone, and extra cost is also required.

  The present invention has been made based on the above circumstances, and its purpose is to maintain high development efficiency of application programs as in the case of adopting a synchronous search method without introducing a large-scale system, And it is providing the data processing apparatus provided with the search function as easy to use as the case where an asynchronous search system is employ | adopted.

  The present invention implements an application execution means for executing an application program and a data search from the data storage means in a data processing device comprising a display means for displaying processing contents and a data storage means for storing various data. A data search means for requesting the data search means to perform a data search in response to receiving a data search instruction, wherein the data search means includes: Search condition accepting means for accepting a search condition setting in response to a data search request from the data search requesting means, and data suitable for the search condition accepted by the search condition accepting means from the data storage means Search execution means for sequentially displaying a list of search results on the display means while searching, and A selection accepting means for accepting a selection of data from the search results search execution means is displayed, is characterized by the selection accepting means and a data response means for responding receives the selection data to said application executing means.

  According to the present invention in which such a measure is taken, without introducing a large-scale system, the development efficiency of the application program is kept high as in the case where the synchronous search method is adopted, and the case where the asynchronous search method is adopted is adopted. It is possible to provide a data processing apparatus having a convenient search function.

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing a control circuit of the data processing apparatus 1. The control circuit of the data processing apparatus 1 includes a control unit 2 that is a control subject, a display device 3, an input device 4, a pointing device 5, a hard disk drive 6, a search mode management unit 7, a data search unit 8, and a function selection receiving unit 9. The application execution unit 10 is connected by a bus line 20 such as a data bus or an address bus.

  The display device 3 is a display such as an LCD (Liquid Crystal Display) or a CRT (Cathode-Ray Tube), and displays various processing contents of the data processing device 1 (display means). The input device 4 is a keyboard on which various operation keys such as numeric keys and alphabet keys are arranged, and accepts an operation input by an operator. The pointing device 5 is, for example, a mouse on which predetermined operation buttons are arranged, and detects and inputs a position change on a plane. Note that the input device 3 and the pointing device 4 constitute input means.

  The hard disk drive 6 has a relatively large data area, and in addition to the data files related to the OS and various utility programs, the search mode file 30, the data file 31, and the application file F-1 to the application file F-n. Is remembered. The application file F-1 to application file Fn are application files related to the application program A-1 to application program An (n; integer) executed by the data processing apparatus 1, and include various types of execution programs. Contains data. The data file 31 is composed of various business data files (information storage means) for information processing using the application programs A-1 to An. This business data file includes, for example, a product data file that stores the sales price and date of manufacture of a product, a customer data file that stores the name and contact information of the customer, and a transaction history data file that stores a transaction history. Etc. The search mode file 30 will be described later with reference to FIG.

  The function selection accepting unit 9 accepts selection of various processes such as execution of an application desired by the operator and system termination processing of the data processing apparatus 1. The operator can select various processes desired to be executed by operating the input device 4 or the pointing device 5 in accordance with the screen display on the display device 3.

  The application execution unit 10 is realized by middleware stored in the hard disk drive 6 and manages execution of the application program A-1 to application program An. The middleware is software that operates on the OS and provides more specific functions than the functions that the OS provides for application programs. When the function selection receiving unit 9 receives execution of a specific application from the application programs A-1 to An, the application execution unit 10 stores application files F-1 to F-1 stored in the hard disk drive 6. A corresponding application file is identified from the application files F-n, and the execution program is executed.

  The data search unit 8 is realized by middleware stored in the hard disk drive 6 similarly to the application execution unit 10, and searches for specific data from the data file 31 in response to a request from the OS or the application execution unit 10. The data search unit 8 has a synchronous mode and an asynchronous mode as data search execution formats. The synchronous mode is a data search mode in which a search result is displayed on the display device 3 after a series of data search from the data file 31 is completed. On the other hand, the asynchronous mode is a data search mode in which search results are sequentially displayed on the display device 3 while searching for data from the data file 31.

  The search mode management unit 7 manages changes in data stored in the search mode file 30. FIG. 2 is a schematic diagram illustrating an example of the data structure of the search mode file 30. The search mode file 30 stores bit data for specifying a data search mode when the data search unit 8 performs a search, and bit data for specifying whether or not a search progress display is performed during the search. (Search mode storage means). The search progress display is a display indicating that data is being searched when data search is being executed in the asynchronous mode. In this embodiment, if the bit data for the data search mode in the search mode file 30 is “0”, the synchronous mode is indicated. If “1”, the asynchronous mode is indicated, and the bit data for the search progress display is “0”. If so, the display is invalid. If it is “1”, the display is valid.

  FIG. 3 is a schematic diagram showing an example of the search progress display 40. The search progress display 40 displays the number of data files that have been searched so far, such as “100 items being searched”. Further, it is configured to indicate that the search can be interrupted by operating a predetermined operation key (for example, Esc key) arranged on the input device 4 such as “Esc: interruption”. If a search error occurs while the search progress display 40 is displayed, the search progress display 40 is switched to the error display 41 shown in FIG. The error display 41 displays an error number for identifying the cause of the error such as “Error (00001)”, and a predetermined operation key (for example, Esc) disposed on the input device 4 such as “Esc: Interruption”. It is configured to display that the error can be cleared by operating the key.

Next, the effect | action by the above structures is demonstrated.
FIG. 5 is a flowchart showing main processing executed by the data processing apparatus 1 in the activated state. When the operator operates a power-on switch provided at a predetermined position on the main body of the data processing apparatus 1, commercial power is taken into the control circuit of the data processing apparatus 1 and system activation is started. After starting the system, first, as ST101, the control unit 2 executes initialization processing of each unit constituting the data processing device 1.

  Next, as ST102, the function selection accepting unit 9 displays the menu screen 50 on the display device 3, and accepts the function selection input by the operator. FIG. 6 is a schematic diagram showing an example of the menu screen 50. The menu screen 50 displays an application selection list 51, an end button 52, and the current system date and time. The end button 52 is a button operated when the system of the data processing apparatus 1 is finished. The application selection list 51 is numbered in ascending order, such as “1. Delivery note”, “2. Sales input”, “3. Invoice”, and the names of the application programs A-1 to An. Is displayed. Incidentally, the “delivery note” is an application program for creating a delivery note by inputting information such as delivery quantity, delivery amount, delivery date and time, and delivery destination. Further, “sales input” is an application program for inputting information such as the sales amount of the day and the sales quantity of the product and calculating the cumulative sales amount, the number of stocks, or the order quantity. The “invoice” is an application program for creating an invoice by inputting information such as the date and time when the document was sent, the contents of the attached document, the sender and the destination. Thus, the operator can select and execute a desired application program from the application programs displayed in the application selection list 51.

  When a predetermined operation key provided on the input device 4 is operated while the menu screen 50 is displayed, a mode setting screen 53 for setting a data search mode (described later in the description of FIG. 7). Is displayed). In the present embodiment, it is assumed that the mode setting screen 53 is displayed when the F1 key provided on the input device 4 is operated.

  When an operation input from the input device 4 or the pointing device 5 is received with the mode setting screen 53 displayed, the function selected by the function selection receiving unit 9 is set as the data search mode, the application program is Determine which is the end of the system.

  When the operation of the F1 key is accepted in the process of ST103, it is determined that the selected function is the data search mode setting ("data search mode setting" in ST103). At this time, as ST104, the search mode management unit 7 displays the mode setting screen 53 and accepts the setting of the data search mode. FIG. 7 is a schematic diagram illustrating an example of the mode setting screen 53. On the mode setting screen 53, option buttons 54, 55, 56, 57, an OK button 58, and a cancel button 59 are arranged. The option button 54 is selected when the data search mode is set to the synchronous mode, and the option button 55 is selected when the data search mode is set to the asynchronous mode. Note that only one of the option buttons 54 and 55 can be selected. The option button 56 is selected when the search progress display is disabled, and the option button 57 is selected when the search progress display is enabled. Only one of these option buttons 56 and 57 can be selected. These option buttons 54, 55, 56, and 57 are selected by operating the pointing device 5, and the operation of the OK button 58 determines the selection of the data search mode.

  When the setting of the data search mode is received in this way, the search mode management unit 7 stores the set data search mode and the presence / absence of search progress display in the search mode file 30 as ST105. That is, when the “OK” button is operated with the option button 54 selected in the “data search mode” column of the search mode file 30, “0” bit data indicating the synchronization mode is stored, and the option button is stored. When the OK button is operated while 55 is selected, bit data of “1” indicating the asynchronous mode is stored. Further, in the “search progress display” field of the search mode file 30, “0” bit data indicating invalidity of the search progress display is stored when the OK button is operated while the option button 56 is selected. When the OK button is operated while the option button 57 is selected, bit data “1” indicating that the search progress display is valid is stored. On the other hand, when the cancel button 68 is operated, the process of ST105 is not performed. Thus, after the OK button 58 or the cancel button 59 is operated, the search mode management unit 7 closes the mode setting screen 53 and returns to the process of ST102. Note that the processing of ST104 and ST105 that accepts the setting of the data search mode and the setting of whether or not to display the search progress display 40 constitutes a search mode setting means and a display permission / inhibition setting means.

  When any application program is selected from the application selection list 51 in the process of ST103, it is determined that the selected function is execution of the application program ("application execution" of ST103). In ST106, the application execution unit 10 executes the selected application program.

  Further, when the operation of the end button 52 is accepted in the process of ST103, it is determined that the selected function is the system end process ("End" in ST103). At this time, as ST107, the control unit 2 executes a system termination process.

  Next, processing after the application program is executed in ST106 will be described with reference to the flowchart of FIG. First, as ST201, the application execution unit 10 executes the application program selected from the application selection list 51, and displays the application execution screen 60.

  FIG. 9 is a schematic diagram showing an example of an application execution screen 60 displayed when the application program for creating the delivery note is executed. On the application execution screen 60, text boxes 61 and 62, a data input field 63, a close button 64, and an end button 65 are arranged. The text box 61 accepts input of date. The text box 62 accepts input of a customer name. The data input field 63 accepts input of the product name, the quantity of the delivered product, the unit price of the product, and the total amount of the delivered product. When the closing button 64 is operated, delivery note data is created based on the data input in the text boxes 61 and 62 and the data input field 63. On the other hand, when the end button 65 is operated, the application program ends.

  The text boxes 61 and 62, the data input field 63, the close button 64 and the end button 65 can be operated or input using the input device 4 and the pointing device 5. Data input to the text boxes 61 and 62 and the data input field 63 is performed by operating various operation keys arranged on the input device 4 after activating a portion desired to be input by operating the input device 4 or the pointing device 5. Do that. In addition to direct input using the input device 4 in this way, data input using an inquiry screen 70 described later in the description of FIG. 10 is possible. The inquiry screen 70 is displayed by the data search unit 8 in response to the operation of the plus key arranged on the input device 4 while the application execution screen 60 is displayed.

  After displaying the application execution screen 60 in the process of ST201, the application execution unit 10 accepts operation inputs from the input device 4 and the pointing device 5 as ST202. When an operation input is received, it is determined in ST203 whether the operation input is data input to the text boxes 61 and 62 or the data input field 63, the operation of the plus key, or the operation of the end button 65.

  When it is determined that the operation input accepted in the process of ST202 is a data input to the text boxes 61 and 62 or the data input field 63 (“data input” of ST203), the application execution unit 10 performs the text box as ST204. 61 and 62 and the data input field 63, the data is input to the currently active input field. Thereafter, the process returns to ST202 again to accept the next operation input.

  On the other hand, when it is determined that the operation input received in the process of ST202 is the operation of the plus key (“display inquiry screen” of ST203), the application execution unit 10 requests the data search unit 8 to request a search. (Data search request means). Upon receiving this command, the data search section 8 displays an inquiry screen 70 for data to be input in the text boxes 61 and 62 and the input field currently active in the data input field 63 in ST205. FIG. 10 is a schematic diagram showing an inquiry screen 70 for customer name inquiry that is displayed when the plus key is operated while the text box 62 is active. The inquiry screen 70 is displayed in front of the application execution screen 60, and includes a search name input field 71, a search button 72, a cancel button 73, a search result display field 74, a page return button 76, and a page feed button 77.

  In the search name input field 71, a character string desired by the operator is input as a search condition using the input device 4 (search condition receiving means). The search button 72 is a command button for executing a search for data including a character string input from the data file 31 to the search name input field 71. The cancel button 73 is a command button for closing the inquiry screen 70 and canceling the inquiry process. In the search result display column 74, the customer name that is the result of searching the character string input to the search name input column 71 from the data file 31 is displayed together with the customer code assigned to each customer. A display field and a scroll bar 75 for browsing and displaying the display contents are arranged. The page return button 76 and the page feed button 77 are command buttons for switching the search results displayed at one time in the search result display field 74 as one page and switching the page unit. By using the page return button 76 and the page feed button 77, display switching can be performed faster than when the scroll bar 75 is used.

  When a character string is input in the search name input field 71 and the search button 72 is operated, the data search unit 8 refers to the search mode file 30 in ST206 and determines the currently set search mode. When “0” is stored in the data area corresponding to the data search mode of the search mode file 30, it is determined that the mode is the synchronous mode (“synchronous mode” in ST 206), and all data stored in the data file 31 are searched. The customer name and customer code including the character string input in the name input field 71 are searched. Thereafter, the data search unit 8 displays the data found as ST208 in the search result display column 74.

  An example of the inquiry screen 70 on which the search result is displayed is shown in FIG. The inquiry screen 70 is a result of executing a search by inputting “shop” in the search name input field 71. In the customer name display field of the search result display field 74, a customer name including the character string of “shop” found from the data file 31 such as “A shop” and “B shop” is displayed. In the code display column, customer codes assigned to each customer such as “100001” and “100002” are displayed.

  At this time, the data search unit 8 receives selection of data by operating the input device 4 and the pointing device 5 from the data displayed in the search result display column 74 (selection receiving means). When the operator selects desired data, the data search unit 8 responds to the application execution unit 10 with the data selected as ST209 (data response means). At this time, the application execution unit 10 inputs the data received from the data search unit 8 in the input field that was active when the inquiry screen 70 was displayed. Thereafter, the data search unit 8 deletes the inquiry screen 70 in ST210, returns to the process of ST202 again, and accepts the next operation input.

  On the other hand, when “1” is stored in the data area for the data search mode of the search mode file 30 in the process of ST206, it is determined that the mode is the asynchronous mode (“asynchronous mode” of ST206), and the data search unit 8 In ST211, data search processing in the asynchronous mode is started. Data retrieval processing in the asynchronous mode will be described later in detail with reference to FIG. Even when the data search is performed in the asynchronous mode, the search results are displayed in a list in the search result display column 74 as in the case of the synchronous mode. Then, the data search unit 8 executes the processes of ST209 and ST210, that is, the input of the data selected by the operator and the deletion of the inquiry screen 70. Thereafter, the process returns to ST202 again to accept the next operation input.

  Here, when the end button 65 is operated in the process of ST203 (“End” of ST203), the application execution unit 10 stores the data currently being worked in the data file 31 as ST212. In ST213, the application execution screen 60 is deleted, and the execution of the application program is terminated.

  Next, the flow of the data search parallel execution process executed by the data search unit 8 after the data search in the asynchronous mode is started in the process of ST211 will be described with reference to FIG. This process is executed in parallel with the execution of the application program by the application execution unit 10. Therefore, the operation of the application execution screen 60 can be performed even while the processing is being executed.

  When the processing is started, first, the data search unit 8 determines whether or not the data search is instructed by the operation of the cancel button 73 in ST301, or whether all the data searches are completed. When it is determined that the cancel button 73 has not been operated and all data searches have not been completed (No in ST301), the data search unit 8 can display one page that can be displayed in the search result display column 74 as ST302. Min data is retrieved from the data file 31. The data searched at this time is displayed in the search result display column 74. Thereafter, in ST303, it is determined whether or not the data search for one page has been normally completed.

  When it is determined that the data search for one page has been normally completed in the process of ST303 (Yes in ST303), the data search unit 8 refers to the search mode file 30 as ST304 and sets the search progress display to be valid. It is judged whether it is done. When “0” is stored in the search progress display data area of the search mode file 30, it is determined to be invalid (No in ST304), and the process returns to ST301 again to determine whether or not the data search is interrupted or completed. to decide.

  On the other hand, when “1” is stored in the search progress display data area of the search mode file 30, it is determined that the search progress display is valid (YES in ST304), and the search progress display 40 is displayed on the inquiry screen 70 as ST305. Is displayed (search progress display means). FIG. 13 is a schematic diagram illustrating an example of an inquiry screen 70 on which the search progress display 40 illustrated in FIG. 3 is displayed. The search progress display 40 is displayed at a predetermined position on the inquiry screen, and the number of searched data files and the like are displayed as described above with reference to FIG. After the search progress display 40 is displayed, the process returns to ST301 again to determine whether or not there is a data search interruption instruction or completion. When the process of ST305 is performed again through the processes of ST301 to ST304, the number of searched data files displayed on the search progress display 40 is counted up. When the Esc key is operated while the search progress display 40 is displayed, the data search process from the data file 31 is interrupted while the inquiry screen 70 is displayed (search interruption means). That is, the operator interrupts the search when determining that the number of searched files has already reached a sufficient number even if the data search for all data stored in the data file 31 has not been completed. Desired data can be selected from the data displayed in the result display column 74.

  When it is determined that the data search for one page has not been completed normally in the process of ST303 (No in ST303), the data search unit 8 displays the search progress display 40 as the error display shown in FIG. Switch to 41. Then, an error cancel input is accepted as ST307. At this time, when the Esc key, which is an error cancel execution key, is operated, the error display 41 is deleted in ST308, and the parallel processing of the data search ends.

  On the other hand, when it is determined in the process of ST301 that there is an instruction to interrupt data search, or when it is determined that the data search is completed (Yes in ST301), the search progress display 40 is deleted and parallel processing of the data search is performed. finish.

  Note that the processing of ST206 to ST208 and ST302, that is, the processing of the data search unit 8 that performs data search in either the synchronous mode or the asynchronous mode according to the settings stored in the search mode file 30, constitutes search execution means. To do.

  As described above, in the data search in the asynchronous mode, unless an error occurs, the processes of ST302 to ST305 are repeated until it is determined that the data search is instructed in the process of ST301 or all the data searches are completed. It is. At this time, the search result display field 74 displays the search result for one page in the process of ST302, and additionally displays the search result for one page in the next process of ST302. The search result for one page is additionally displayed every time the process of ST302 is executed until the process is completed. As a result, in the asynchronous mode data search, search results for one page are sequentially displayed in the search result display column 74.

  As described above, in the data processing device 1, the data search by the data search unit 8 is executed independently of the execution of the application program by the application execution unit 10. Therefore, it is not necessary to embed data retrieval programs in the application program itself at the application program development stage, and even developers without parallel processing programming knowledge can easily develop application programs that incorporate the data retrieval method in asynchronous mode. Can do.

  The data search unit 8 and the application execution unit 10 are realized by middleware. Therefore, an asynchronous data search method can be used without introducing a large-scale system in which a host device such as a search server is installed.

  In addition, since the data search in the synchronous mode and the data search in the asynchronous mode can be changed by an operation from the mode setting screen 53, the optimum search mode can be set according to the purpose of use of the operator. it can.

  In addition, since data search progress information is displayed on the search progress display 40 during data search in the asynchronous mode, the operator determines that a sufficient number of files have already been searched or is in the middle of the search. However, when it is confirmed that the search result is already displayed in the search result display column 74, the search can be interrupted. Therefore, time for performing useless data search can be omitted.

  In addition, this invention is not limited to the said embodiment as it is, In an implementation stage, in the range which does not deviate from the summary, each component can be deform | transformed and embodied suitably.

  For example, the search mode file 30 stores data search mode settings and whether or not to display search progress display, but stores only data search mode settings and whether or not to display search progress display. These settings may be managed by a separate file.

  The search progress display 40 displays the number of files that have already been searched for data. However, the present invention is not limited to this, and other search progress information such as the number of data found so far can be displayed. Also good.

  In the search in the asynchronous mode, every time one page of data displayed in the search result display column 74 is found, the found data is additionally displayed. However, the present invention is not limited to this, and a smaller number of data is displayed. It may be displayed additionally when it is discovered, or may be additionally displayed when a larger number of data is discovered.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from the overall components shown in the embodiment.
