Description

  The present invention relates to a terminal device, a data search system, a data search method, and a data search program. In particular, a terminal device that searches for and displays predetermined data such as a mobile phone, and uses such a terminal device. The present invention relates to a data search system, a data search method, and a data search program.

  Access to a network such as the Internet has been actively performed, and data retrieval performed by a terminal device such as a mobile phone can be easily performed by anyone using the network. For example, in a portable terminal device such as a mobile phone or a PHS (Personal Handyphone System), data such as an address book and a schedule table can have a large capacity as compared with a built-in memory of the device. Therefore, there is a method in which such data is stored in a server on the network, only the corresponding data is searched when necessary, and downloaded to the terminal device side.

By the way, when searching for data having a hierarchical structure stored in a network, data belonging to the lower layer is also searched and cached in the background in advance when data of the upper layer is requested. It has been proposed as a related technique (see, for example, Patent Document 1). In this related technique, when a terminal device makes a search request to a database on a network, not only the upper layer data that is the target of the request but also data belonging to the lower layer is acquired. Accordingly, when data belonging to the lower layer is required later, it can be retrieved from the cache memory of the terminal device, and at that time, the data can be retrieved at high speed.
JP-A-9-305473 (paragraph 0007, FIG. 1)

  However, in this related technique, for data having a hierarchical structure, data exceeding the initially requested search range is always sent to the terminal device side as data belonging to the lower layer. In this case, the terminal device side may next request data belonging to the lower layer, and in this case, the data stored in the cache memory can certainly be used, and high-speed data processing becomes possible. .

  However, the terminal device often requires a search result only within a range originally requested at a later time. In such a case, since the lower layer data is also sent to the terminal device in response to the request for acquisition of the upper layer data, the processing time becomes longer. In addition to this, there is a problem in that the amount of data larger than the requested data is sent to the terminal device as the search result, resulting in an increase in the size of the cache memory for temporarily storing the data.

  Accordingly, an object of the present invention is to provide a terminal device, a data search system, a data search method, and a data search program capable of acquiring search results within a requested range and speeding up the processing therefor. .

  In the present invention, (b) a predetermined plurality of items can be arbitrarily searched for a database that holds a group of data extracted as a search result as a data structure divided into a plurality of predetermined items.

The terminal device is provided with display control means for sequentially displaying one search result as a stepwise display.

  In the present invention, (a) a database that holds a set of data extracted as a search result as a data structure that is subdivided into a plurality of predetermined items, and (b) the above-described predetermined for the database. Search result request means for setting a plurality of stages of search result acquisition requests that are arbitrarily assigned as a search target, and sequentially executing the plurality of stages of search result acquisition requests at different times; C) search result storage means for storing the search results of each stage extracted and sent from the database in response to the request of the search result request means in corresponding storage areas; and (d) these storages. The data search system includes display control means for sequentially displaying the search results stored in the area as a stepwise display of one search result.

  Further, in the present invention, (a) a predetermined plurality of items can be arbitrarily searched with respect to a database that holds a set of data extracted as a search result as a data structure subdivided into a plurality of predetermined items. (B) a search result request step in which a plurality of search result acquisition requests allocated as targets are set, and the multiple stages of search result acquisition requests are executed sequentially at different times; A search result storage step for storing the search results of each stage extracted and sent from the above-mentioned database in response to a request by the above, and (c) a storage area in the search result storage step. The data search method includes a display control step for sequentially displaying the search results stored in the data as a stepwise display of one search result. .

  Furthermore, according to the present invention, the data of the terminal device that requests the search result is stored in a database that holds a group of data extracted as the search result as a data structure divided into a plurality of predetermined items. As a search program, (a) a plurality of stages of search result acquisition requests in which a plurality of predetermined items are arbitrarily assigned as search targets are set, and the search results of these stages are acquired sequentially at different times.

The extraction request receiving unit 146 is configured to receive search and read requests for the database 106. The extraction execution unit 147 executes extraction of requested data. The search result is returned to the request destination. The database 106 stores a set of data used by the terminal device 101 such as an address book and a schedule table.

  The server device 103 also performs control by the CPU executing a control program. That is, the extraction request reception unit 146 and the extraction execution unit 147 functionally implement circuit operations by executing respective control programs.

  FIG. 4 shows an area which is an address book of a certain user in the database used for display in the present embodiment. In the database 106, IDs for identifying data, names of individuals described in the address book, phonetic names of names, telephone numbers as contacts, e-mail addresses, addresses, affiliations and additions of organizations such as companies A memo as a description item is stored as an item to be displayed.

  The address book data stored in the database 106 is classified into address list data and address detail display data. Of these, the address list data is a part of all items of the address data, and in this embodiment, the items of ID, name, and telephone number with an asterisk (*) in FIG. 4 correspond to this item. To do. The detailed address display data is all items of address data. In this embodiment, ID, name, phonetic, telephone number, mail address, address, affiliation, and memo correspond to this.

  An outline of the operation of the data display system 100 will be briefly described with reference to FIGS. The user sets items necessary for list display in the list display search unit 128 of the terminal device 101, for example, with the contents indicated by an asterisk (*) in FIG. Based on this setting, the list display search unit 128 extracts data items necessary for list display from all data in the database 106 and stores them in the first storage area 131 in advance. The display control unit 126 performs a process of reading the list display data from the first storage area 131 by the number that can be displayed and causing the display unit 107 to display it.

  The detailed display search unit 129 requests the detailed display data from the database 106 of the server apparatus 103 while the display control unit 126 displays the list display data. The request for the detailed display data is made based on the ID of the list display data that the data ID notification unit 130 has. The detailed display search unit 129 receives an arbitrary number of detailed display data from the database 106 of the server apparatus 103 and stores the detailed display data in the second storage area 132. When receiving a request for displaying the detailed display data from the list display data from the user, the display control unit 126 reads the detailed display data from the second storage area 132 and displays it on the display unit 107. .

  FIG. 5 and FIG. 6 show the flow of overall processing for displaying an address book in such a data display system. It demonstrates with FIGS. 1-3.

  When the address book application program is activated, the main control unit 123 of the terminal device 101 reads the previously stored list display data (cache) from the second storage area 132 (step S201), and uses this to display the address book data. An initial screen is displayed on the display unit 107 (step S202).

  FIG. 7 shows an example of the display state of the initial screen of the address book. The address book display screen 151 shown on the display unit 107 in FIG. 1 includes an address display area 152 and an address head line selection area 153. A vertical scroll bar 154 is disposed at the right end of the address display area 152, and by operating this, information other than the display frame currently displayed can be scrolled and displayed. In the example shown in FIG. 7, detailed information regarding the addresses of two people is displayed. In the present embodiment, address information for up to 10 addresses is simultaneously acquired from the database 106 shown in FIG. Therefore, if there is remaining address information, it can be sequentially displayed in the address display area 152 by operating the vertical scroll bar 154.

  In the address first row selection area 153 located on the right side of the address book display screen 151, a plurality of buttons 155 in which the first character of the address is written are displayed. If the content displayed in the address display area 152 does not correspond to the “line” of the address that the user wants to find, the user of the terminal device 101 presses the corresponding “line” button to display that line. Will be displayed in the address display area 152.

  Returning to FIG. When the initial screen as shown in FIG. 7 is displayed in step S202, the main control unit 123 selects a different address head line by the user (step S203), or a different address (information) of the currently displayed line. Is selected (step S204), or the display of the address book is terminated while viewing the current display contents (step S205).

  When one of the buttons 155 in FIG. 7 is pressed and the first line of the address is selected (step S203: Y), it is checked whether a line different from the currently displayed line has been selected. Performed (step S206). If the same row as the currently displayed row is selected (N), it is useless to access the server device 103 via the network 102, so the standby state (steps S203 to S205) is maintained. To do.

  On the other hand, when a line different from the currently displayed line is selected (step S206: Y), the main control unit 123 controls the communication control unit 125 to access the server apparatus 103 via the network 102. The list display data of the corresponding row is read from the database 106 and stored in the first storage area 131 (step S207). Then, as shown in FIG. 6, it is checked whether the display of the address book is continued at this time (step S208). If it is continued (Y), the address display on the address book display screen 151 shown in FIG. The contents currently displayed in the area 152 are erased, and instead, display of addresses by the currently acquired list display data is started (step S209). If it is determined in step S208 that the address display state has ended (N), the series of address book display processing ends (END). For example, a case where the user ends an application program for displaying an address book is an example.

  When the list display data is displayed in the address display area 152 in step S209, the main control unit 123 acquires the ID of the list display data that is the display target (step S210). Based on these IDs, the corresponding detailed display data is read from the database 106 of the server device 103 and stored in the second storage area 132 (step S211). At this time, the three items (ID, name, phone number) read out as the list display data in step S207 need not be read out redundantly. When the detailed display data is stored in the second storage area 132, it is checked whether the display of the address book is continued at this time (step S212). If the display is not continued (N), a series of display of the address book is displayed. The process ends (END).

  On the other hand, when the display of the address book is continued (step S212: Y), all items of the address book are used instead of the simple display displayed in the address display area 152 of the address book display screen 151. The display of the detailed display data for (ID, name, phonetic, phone number, mail address, address, affiliation, memo) is started (step S213). In a state in which the detailed display data of the corresponding line in the address book is being displayed, the main control unit 123 selects whether the user selects a different first address line (step S214), or a different address on the currently displayed line. It waits for which of the three selections to select (information) (step S215) or to terminate the display of the address book while viewing the current display contents (step S216).

  When the user selects a line different from the currently displayed line (step S214: Y), the process returns to step S207 in FIG. 5 to start the same process as that already described for the designated line. . On the other hand, an address (information) different from the currently displayed address (information) in the corresponding line, such as when the user operates the vertical scroll bar 154 (FIG. 7) to display the last display area. ) Is selected (step S215: Y), the list display data of the requested corresponding location is read from the database 106, and this is additionally stored in the first storage area 131 (step S217). ). For example, it is assumed that the “A” line is designated first, and the list display data for the ten address books from the top is stored in the first storage area 131. At this time, when a further address (information) about the “A” line is requested, list display data for the 11th to 20th address books from the top is added to the first storage area 131. Stored in the form of

  Thereafter, the main control unit 123 returns the process to step S208. As a result, these additional list display data are additionally displayed in the address display area 152 so as to be continuous with the display contents so far (step S209). Then, an ID corresponding to the additional list display data at this time is acquired (step S210), and based on this, the corresponding detailed display data is read from the database 106 and added to the second storage area 132. (Step S211). If the display of the address book continues (step S212: Y), the display of these detailed display data is added to the address display area 152 of the address book display screen 151 (step S213). .

  On the other hand, when the address display state ends after the display of the detailed display data is started in step S213 (step S216: Y), the series of address book display processing ends (end).

  When a different address (information) in the corresponding row is selected in step S204 (Y), the process proceeds to the above-described step S217 and the process is performed. If the address display state ends in step S205 (Y), a series of address book display processing ends as described above (END).

  Note that, unlike the above control, the display control program, the list display search program, the detailed display search program, and the data ID notification program can be linked to perform the address book display processing. For example, the list display search program executes a process of storing the list display data acquired from the database 106 (FIG. 3) in the first storage area 131, or the processes of steps S208, S212, and S216 of FIG. Is realized as a process for checking whether the display control program is being executed, or requests the corresponding detailed display data from the database 106 based on the ID of the list display data obtained by the data ID notification program. You may do it.

  By linking a plurality of programs in this way, for example, in the time zone when the display control program is performing the data display operation, the data ID notification program acquires the ID of the data to be read next, and the detailed display search program Parallel processing such as starting reading of the next data from the database 106 becomes possible. That is, for example, the processes shown in steps S209 to S211 in FIG. 6 can be performed in parallel while actually overlapping the times.

  FIG. 8 shows the relationship of the control programs that operate in the data display system of the present embodiment described above. In the terminal device 101 constituting the data display system 100, a first storage area 131 for storing list display data for display and a second storage area 132 for storing detailed display data for display. Is present. Inside the server apparatus 103, a database 106 storing these list display data and detailed display data is arranged.

  The list display search program 171 constituting the list display search unit 128 in FIG. 2 includes a list including several items for list display from the database 106 of the server apparatus 103 connected to the terminal apparatus 101 via the network 102. Display data is read out and stored in the first storage area 131. The display program 172 corresponding to the display control unit 126 in FIG. 2 displays this.

  The data ID notification program 173 corresponding to the data ID notification unit 130 in FIG. 2 is included in the list display data while the display program 172 displays the list display data stored in the first storage area 131. The ID is extracted and passed to the detailed display search program 174 corresponding to the detailed display search unit 129 of FIG. Based on this ID, the detailed display search program 174 reads the corresponding detailed display data from the database 106 and stores it in the second storage area 132. The display program 172 displays the detailed display data in a form of supplementing the list display data.

  According to the data display system of the present embodiment described above, the first and second storage areas 131 and 132 are provided in the terminal device 101. First, list display data in a predetermined range is stored in the first storage area 131. The detailed display data corresponding to the list display data stored in the first storage area 131 is stored in the second storage area 132. In this way, by storing the data to be displayed separately for the list display and the detail display, the limited storage area of the terminal device 101 can be used effectively. Moreover, not only the data required by the user but also the data items that should be grasped first can be displayed in a form that has been selected first. Since data to be displayed can be read out, the data display processing becomes faster.

  Further, according to the present embodiment, since only the items necessary for list display are stored and displayed in the storage area at the initial list display stage, the storage area can be used efficiently. Further, while performing the list display, the next stage display data is read asynchronously from the database of the server device, stored in the storage area of the terminal device, and data used for the next stage display processing is prepared in advance. Therefore, stepwise display processing can be performed at high speed.

  Furthermore, according to the present embodiment, since the previous search result is displayed before the current search, it is possible to eliminate the waste of performing the same search repeatedly. Since the search results are displayed step by step, the search can be stopped or the next search can be performed when the required display content is performed, rather than displaying all of the search content suddenly. There is no waste in processing.

  Furthermore, according to the present embodiment, items are divided for each search target such as an address book or a schedule table, and a stepwise search is performed. Therefore, different data holding means are prepared for each data type. can do.

  <Deformability of invention>

  The present invention is not limited to the embodiment described above, and various modifications can be made.

  FIG. 9 shows an outline of the configuration of the data display system in the modification of the present embodiment, and corresponds to FIG. 9, the same parts as those in FIG. 8 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

This in terminal device 101A constituting the data display system 100A, the first through the storage area 133 ₁ to 133 _m of the m storing these divided into display data of various display stages of are present. Inside the server apparatus 103A, a database 106A from which display data at each stage can be read is arranged. Here, for example, list display data is stored in the first storage area 133 ₁ , and simple display data is stored in the second storage area 133 ₂ , for example. For example, detailed display data is stored in the m-th storage area 133 _m .

The first search program 175 ₁ reads list display data including a number of items for list display from the database 106A of the server apparatus 103A connected to the terminal apparatus 101A via the network 102. 1 storage area 133 ₁ . The display program 172A corresponding to the display control unit 126 in FIG. 2 displays this.

The data ID notification program 173 ₂ corresponding to the data ID notification unit 130 in FIG. 2 displays this list display data while the display program 172A displays the list display data stored in the _first storage area 133 _1. since by extracting the ID included in the first stage before the list display data, and passes it to the second search program 175 _2. The second search program 175 ₂ reads the corresponding simple display data from the database 106A based on this ID, and stores it in the second storage area 133 ₂ . As a result, the display program 172A displays simple display data on a display unit (not shown) instead of the list display data.

Thereafter, display control is similarly performed. The data ID notification program 173 _m corresponding to the last m-th storage area 133 _m causes the display program 172A to display the list display data stored in the _m−1-th storage area 133 _{m−1 (} not shown). In the meantime, the ID included in the display data one stage before the display target is extracted and passed to the m-th search program 175 _m . Based on this ID, the m-th search program 175 _m reads the corresponding detailed display data from the database 106A and stores it in the m-th storage area 133 _m . Based on this, the display program 172A displays the detailed display data on the display unit.

  FIG. 10 shows a general display data processing on the terminal device side. This will be described with reference to FIG.

  When a search request for the database 106A is generated for display in the terminal device 101A (step S231: Y), the parameter a for controlling the display stage is initialized to a numerical value “1” (step S232). Then, search processing for the a-th display data such as list display data is performed on the database 106A (step S233).

When the display data of the a from the database 106A is sent to the terminal apparatus 101A, which stores in the first storage area 133 ₁ corresponding, performs display processing by using a display program 172A, the key of the next display Is acquired (step S234). Then, the numerical value of the parameter a is incremented by “1” (step S235). Then, the numerical value of the parameter a after the count-up is compared with the maximum number m of data display, and it is determined whether it has become larger than this (step S236).

  If it is not larger (N), the next stage display is possible. Therefore, the process returns to step S233 to execute the search processing for the a-th display data as the display stage. Then, similar processing is executed in order, and the processing returns to step S236. When the numerical value of the parameter a after counting up exceeds the maximum number m of data display at a certain point in this way (step S236: Y), the data processing by the search is terminated (end).

  In the above process, the ID is acquired each time in step S234. However, in the case of a system in which the ID itself does not change at the display data acquisition stage, the ID acquired in the first process is stored in a predetermined storage area. The search target of the database 106A may be determined together with the change in the numerical value of the parameter a.

  According to the embodiment of the modification described above, not only can the effect of the embodiment described above be exhibited, but also an appropriate display according to the search content can be achieved by arbitrarily setting the display stage. It becomes possible.

  In the embodiment and the modification of the present invention, the database is arranged in one server device. However, the database may be arranged in each of a plurality of server devices. The target item may be divided and possessed. For example, a certain database covers items related to list display, and another database may cover items other than items related to list display.
