DATA PROCESSING SYSTEM UTILIZING GEOGRAPHIC INFORMATION AND DATA PROCESSING PROGRAM
There are provided an area designating unit 3 for designating a desirable area on a map in a state in which data stored in a first database 11 including geographic information is visualized on the map, an association item designating unit 4 for designating association of an optional data item included in the first database 11 and an optional data item included in a second database 12, and a data retrieving unit 5 for extracting, from the first database 11, data of a data item designated as an association source item in data sets linked to the geographic information associated with the designated area, retrieving the second database 12 with, as a target, a data item designated for an association destination item by using the extracted data as a retrieval key, and extracting data sets which are coincident with the retrieval key.
1 . A data processing system utilizing geographic information comprising:
a visualizing unit for visualizing and displaying data included in a first database having geographic information as a data item or a calculation result for the data on a map based on the geographic information;
an area designating unit for designating a desirable area on the map based on a user operation;
an association item designating unit for designating an optional data item included in the first database as an association source item and designating, as an association destination item, an optional data item included in a second database which is different from the first database based on the user operation; and
a data retrieving unit for extracting, from the first database, data of the data item designated as the association source item by the association item designating unit in data sets linked to geographic information associated with the area designated by the area designating unit, retrieving the second database with, as a target, the data item designated as the association destination item through the association item designating unit by using the extracted data as a retrieval key, and extracting data sets including the retrieval key in data of the association destination item from the second database.
2 . The data processing system utilizing geographic information according to claim 1 further comprising a data aggregating unit for performing aggregation by a designated method with, as a target, the data sets extracted from the second database by the data retrieving unit.
3 . The data processing system utilizing geographic information according to claim 1 , wherein the second database is a database having no geographic information as a data item.
4 . The data processing system utilizing geographic information according to claim 1 further comprising a first database designating unit for designating the first database based on a user operation.
5 . The data processing system utilizing geographic information according to claim 4 further comprising a second database designating unit for designating the second database based on a user operation.
6 . A data processing program utilizing geographic information for causing a computer to function as:
visualizing means for visualizing and displaying data included in a first database having geographic information as a data item or a calculation result for the data on a map based on the geographic information;
area designating means for designating a desirable area on the map based on a user operation;
association item designating means for designating an optional data item included in the first database as an association source item and designating, as an association designation item, an optional data item included in a second database which is different from the first database based on the user operation; and
data retrieving means for extracting, from the first database, data of the data item designated as the association source item by the association item designating means in data sets linked to geographic information associated with the area designated by the area designating means, retrieving the second database with, as a target, the data item designated as the association destination item through the association item designating means by using the extracted data as a retrieval key, and extracting data sets including the retrieval key in data of the association destination item from the second database.
7 . The data processing program utilizing geographic information according to claim 6 for causing the computer to further function as data aggregating means for performing aggregation by a designated method with, as a target, data sets extracted from the second database by the data retrieving means.
8 . The data processing system utilizing geographic information according to claim 2 , wherein the second database is a database having no geographic information as a data item.
9 . The data processing system utilizing geographic information according to claim 8 further comprising a first database designating unit for designating the first database based on a user operation.
10 . The data processing system utilizing geographic information according to claim 2 further comprising a first database designating unit for designating the first database based on a user operation.
11 . The data processing system utilizing geographic information according to claim 3 further comprising a first database designating unit for designating the first database based on a user operation.
12 . The data processing system utilizing geographic information according to claim 11 further comprising a second database designating unit for designating the second database based on a user operation.
13 . The data processing system utilizing geographic information according to claim 1 further comprising a second database designating unit for designating the second database based on a user operation.
14 . The data processing system utilizing geographic information according to claim 2 further comprising a second database designating unit for designating the second database based on a user operation.
15 . The data processing system utilizing geographic information according to claim 3 further comprising a second database designating unit for designating the second database based on a user operation.
16 . The data processing system utilizing geographic information according to claim 8 further comprising a second database designating unit for designating the second database based on a user operation.
17 . The data processing system utilizing geographic information according to claim 9 further comprising a second database designating unit for designating the second database based on a user operation.
18 . The data processing system utilizing geographic information according to claim 10 further comprising a second database designating unit for designating the second database based on a user operation.
