  The terminal computer 4 b includes a layer name acquisition unit 13 that accesses the management server 12 and acquires a layer name from the layer name table 2 in the control unit 33. Access to the management server 12 by the layer name acquisition unit 13 is made at predetermined time intervals using the address of the management server 12 stored in the storage unit (statistical information storage unit) 20 and the two names of the layer name table. The layer name thus displayed is displayed on the display device 15 by the layer name display means 16. In addition to the above, the layer name acquisition unit 13 also acquires the data name of the map data described above, and the layer name display unit 16 causes the display device 15 to display the data name of the map data.

  Further, the terminal computer 4b acquires the GIS data by using the above-mentioned in-client data server 4a (5), the management server 12, and the data server 5, and displays the GIS data with a request generation means 18 and a superimposed display. Means 19. The request generation means 18 acquires the data stored in the above-mentioned client data server 4a (5) according to the command input via the input device 14 described above, and in this way, the client data server 4a. Along with the data acquired from (5), a command for acquiring the map data stored in the data server 5 and the layer data stored in the data server 5 or generated by the management server 12 is generated.

Then, a drawing assist tool 49 for drawing a processing symbol 59, a data symbol 60, a line symbol 61, and a symbol 62 indicating display processing is displayed in the display image. In this embodiment, the drawing assist tool 49 is configured by using the outputs of the data name display means 43 and the layer name display means 16 as they are, except for the display of the symbol 62 indicating display processing. The upper window of FIG. 7A is a column 49a displaying the data name of the data server layer name table 2a, the data name of the map data, and the data name of the data name table 57, and the lower window is the management server layer name table 2b. This is a column 49b for displaying the data name.

  The creation of the flowchart by the flowchart creation tool 45 can be performed using the data name of the data displayed by the data name display means 43, the layer data displayed by the layer name display means 16, and the data name of the map data. Specifically, for example, by inputting from the input device 14, address data names, layer data names, and map data names of a plurality of sales stores are dragged and dropped from the display position into the flowchart creation area 46. The corresponding processing symbols 59 and data symbols 60 are drawn and displayed in the flowchart creation area 46 in a preset drawing mode. In addition, by designating a line area with the mouse 14 described above, a line symbol 61 can be drawn between the data symbol 60 and the processing symbol 59. Note that data relating to the drawing mode such as the processing symbol 59 is stored in the storage unit 20 of the terminal computer 4b.

The input / output concept of the elements such as the processing symbol 59 and the data symbol 60 connected by 61 is defined as indicating the input / output direction by the direction of the arrows constituting the line symbol 61. Therefore, specifically, the data symbol 60A (“map”) in the lower stage is set so that the arrow is directed to the symbol 62 (the symbol “analysis map” in FIG. 7A) indicating the display processing described above. Are connected to each other, thereby defining a job for displaying map data corresponding to the data symbol 60A. Similarly, the symbol labeled “Store” at the top in FIG. 7A is a data symbol 60B indicating address data of a plurality of sales stores, and the second row from the top in FIG. 7A. The symbol described as “address matching” is the processing symbol 59A for obtaining the longitude and latitude coordinates corresponding to the address, using the address data as an argument, and the data symbol 60B described above is an arrow in the processing function. By connecting so as to be directed, a job whose longitude and latitude coordinates and the like are obtained from the addresses of a plurality of sales stores is defined.

  Further, the request management means 58 executes data in the client data server 4a (5) or the data server 5 corresponding to the data symbol 60 included in the flowchart in order to execute each job of the flowchart generated as described above. The management server 12 is requested to perform the calculation process corresponding to the processing symbol 59 and the calculation result. Specifically, the request management means 58 decomposes the flowchart into a plurality of objects for each line symbol 61, in other words, extracts the object from the flowchart, and each variable and function is based on the data symbol 60 or the processing symbol 59. The objects specified in this way are further associated with each other based on the line symbol 61 to generate a command for the management server 12. As described above, the processing symbol 59 drawn in the flowchart is associated with the corresponding layer name of the layer name display means 16, and this association can be used when extracting the object. Prior to the generation of the command to the management server 12, when the data indicated by the data symbol 60 included in the flowchart is stored in the in-client data server 4a (5), the above-described data name table 57 is referred to. Then, after obtaining the data from the in-client data server 4a (5), an instruction for the management server 12 is output to the management server 12 with reference to the layer name table 2 together with this data. Furthermore, the request management means 58 extracts all the data symbols 60 and processing symbols 59 included in the flowchart, and includes the data symbols 60 corresponding to the map data as described later, and the data corresponding to the layer data. It is verified that the symbol 60 or the processing symbol 59 is included, and it is ensured that the flowchart can display the GIS data by the layer data.

  Therefore, the operator of the terminal computer requests GIS data in various display modes without coding work by generating a flowchart by combining various data and processes displayed by the layer name display means 16 or the like. be able to. Further, the request contents of the GIS data can be easily grasped in the form of a flowchart. As described above, there is a concern that the flowchart may not be properly created due to an operation error due to securing the degree of freedom in creating the flowchart, but in response to such a case, each data symbol 60 and processing Since the appropriate input / output destinations are set in advance corresponding to each of the symbols 59 and the layer data and the like are configured, the symbols 59 are also appropriate even when the line symbols 61 are not properly connected, for example. GIS data can be requested. For connection of such a line symbol 61, a connection relationship between a function and a variable is set in advance, and whether or not connection is possible or whether the connection itself is automatically determined by automatic determination and correction may be made. Is possible.

  The superimposing display means 19 displays the map data and layer data returned from the management server 12 in response to the above request. This superposition is performed using position data included in each of the map data and the layer data, specifically, data relating to the above-described longitude and latitude coordinates.

  On the other hand, in order to output the map data and the layer data to the client 4 in response to the GIS data request output from the client 4 as described above, the management server 12 described above includes the request analysis unit 8 and the element acquisition / generation. Means 9. As described above, the request analysis means 8 is a group of objects that are output from the input / output unit 47 of the client 4 (terminal computer 4b) and received via the input / output unit 48 of the management server 12, that is, map data names, layers The data name and the information related to these associations are decomposed into respective elements, and the map data corresponding to the map data name and the layer data acquisition command corresponding to the layer data name are stored in the in-client data server 4a (5). It outputs to the element acquisition / generation means 9 together with the obtained position data. As described above, the position data, which is address data, is converted into coordinate data such as longitude and latitude coordinates by the conversion means 11 described above. Note that if the above-described information relating to the association requires an arithmetic processing to be performed on the obtained layer data, an instruction for the arithmetic processing is output to the element acquisition / generation unit 9.

  The element acquisition / generation unit 9 refers to the layer name table 2 in response to a request from the request analysis unit 8 and uses the position data stored in the in-client data server 4a (5) to Map data and layer data corresponding to the layer data name are acquired from the data server 5 or are generated by the layer data generating means 1. When acquiring map data, the map area to be acquired is specified using the position data stored in the in-client data server 4a (5). In addition, when calculation processing is required for the obtained layer data, the layer data is output to the layer data generation means 1 to generate further layer data. The map data and layer data acquired as a result are output to the client 4 by the transmission means 10 described above together with information such as longitude and latitude coordinates.

  FIG. 5 shows the flow of processing performed by the request generation unit 18 and the superimposed display unit 19 of the client 4 and the request analysis unit 8 and the element acquisition / generation unit 9 of the management server 12 described above. First, the flowchart creation tool 45 is activated in the client 4 (terminal computer 4b), and the data symbol 60 and the processing symbol 59, that is, the elements constituting the flowchart process are input to the flowchart creation area 46 by an instruction from the input device 14, or When the line symbol 61 is input (step S1), the data symbol 60 and the like are drawn in the flowchart creation area 46 by the flowchart creation tool 45 (step S2). When the input of the data symbol 60 or the like is completed (step S3), and an execution command, that is, a request generation command is input by the input device 14 (step S4), for example, designation specifying position data in any step of the flowchart And a request for the management server 12 is generated after it is verified that the specification regarding the layer data is included.

  The verification operation can be performed, for example, by extracting the data symbol 60 from the flowchart and determining whether there is a data symbol 60 corresponding to any data stored in the database 38. On the other hand, for the verification of the designation regarding the layer data, for example, in the flowchart, it is indirectly determined, for example, by determining whether a plurality of data symbols 60 indicating map data are connected by the line symbol 61 with respect to the symbol 62 indicating display processing. Can be done automatically. As a result of the above verification, if there is no designation related to position data, the designation regarding position data is added as if the position data related to a predetermined position set in advance is designated, and the lack thereof is compensated. The In addition, when the specification regarding the layer data is not included, the map data is changed to a single number to compensate for the defect. Or it is good also as a structure which displays an error on the display apparatus 15 of the terminal computer 4b, and prompts specification of position data or layer data again. In place of the above, for example, whether or not the processing symbol 59 other than the data symbol 60 indicating the map data and the data symbol 60 are connected by the line symbol 61 to the symbol 62 indicating the display processing in the verification of the designation regarding the layer data. It is also possible to improve verification accuracy by determining the above.
