Abstract

The purpose of the present invention is to provide a graphical user interface which enables to show with graphs, as in FIG. 1, the quantity of and the logical relation between the sets of the database retrieved, to calculate and manipulate the sets by pointing the area of the rectangular shapes of the graphs, and to extract the data by pointing the area of the rectangular shapes of the graphs. The program of the present invention communicates with the database query language program through message exchanges between the programs or message exchanges at the terminal systems connected with the communication network, generates the retrieval instructions of the query language program by way of set creating, set drawing, set selection, set projection, and set extraction, and performs the input operation in place of the user. The present invention facilitates simple retrieval processing and supports logical thinking of the user to evaluate and judge the quantity of the set and the relation between the sets.

Claims

1. A database retrieval method comprising the steps of:

a) selecting a first space object database;

b) creating a plurality of set objects for retrieval of data from said space object database;

c) displaying a visual representation of said plurality of set objects, wherein said display gives overlapping areas of said visual representation when data in said set objects is the same;

d) selecting one or more areas of said display; and

e) extracting data from said space object which is within said one or more areas selected.

2. The retrieval method of claim 1 wherein said plurality of sets does not exceed three.

3. The retrieval method of claim 1 further comprising the step of displaying a number of hit elements within one or more areas of said display.

4. The retrieval method of claim 1 further comprising the steps of:

pre-registering set object definitions, and

selecting at least one of said created plurality of set objects by selecting said pre-registered set object definitions.

5. The retrieval method in accordance with claim 2 wherein a count of each of said created set objects is displayed on a screen of a graphical display unit.

6. The retrieval method in accordance with claim 1 wherein said visual representation display shows a logical relationship among the created set objects.

7. The retrieval method in accordance with claim 6 wherein said visual representation display is a geometric rectangular region.

8. The retrieval method in accordance with claim 6 further comprising the step of displaying a logical statement of the relationship of the created set objects.

9. The retrieval method in accordance with claim 1 further comprising the steps of:

creating a first data base set object from said extracted data of said first data base;

selecting a second space object data base;

creating a second data base set object which is defined by one or more set objects selected from said second data base;

creating a first visual display of said first data base set object;

creating a second visual display of said second data base set object;

displaying a visual representation of said first visual display of said first data base set object and of said second visual display of said second data base set object; and

extracting data from said first and second data bases which is within one or more areas selected from said first visual display of said first data base set object and of said second visual display of said second data base set object.

10. The retrieval method in accordance with claim 1 wherein said visual representation is drawn in a mode selected from the group consisting of rate, fit, and zoom.

11. A database retrieval apparatus comprising:

a) a means for selecting a space object database;

b) a means for creating a plurality of set objects for retrieval of data from said space object database;

c) a means for displaying a visual representation of said plurality of set objects, wherein said display gives overlapping areas of said visual representation when data in said set objects is the same;

d) a means for selecting one or more area of said display; and

e) a means for extracting data from said space object which is within said one or more areas selected.

12. The retrieval apparatus of claim 11 wherein said plurality of sets does not exceed three.

13. The retrieval apparatus of claim 11 further comprising a means for displaying a number of hit elements within one or more areas of said display, and said space object.

14. The retrieval apparatus of claim 11 further comprising:

a means for pre-registering set objects, and

a means for selecting at least one of said created set of objects by selecting said pre-registered set object.

15. The retrieval apparatus in accordance with claim 11 wherein a count of said created set objects is displayed on a screen of a graphical display unit.

16. The retrieval apparatus in accordance with claim 11 wherein said display shows a logical relationship among the created set objects.

17. The retrieval apparatus in accordance with claim 16 wherein said display is a geometric rectangular region.

18. The retrieval apparatus in accordance with claim 16 further comprising a means for displaying a logical statement of the relationship of the created set objects.

19. The retrieval apparatus in accordance with claim 11 further comprising:

a means for creating another set object from a space object database;

a means for creating another set object which is defined by the one or more areas selected when logically combined;

a means for displaying a visual display of said another set object obtained from a space object database;

a means for displaying a visual display of said object which is defined by one or more areas selected when logically combined;

a means for selecting one or more areas of said second visual display; and

a means for extracting data from said space object which is within one or more areas selected from said second visual display.

20. The retrieval apparatus according to claim 11 wherein said visual representation is drawn in a mode selected from the group consisting of rate, fit, and zoom.
