Abstract

A system and a method are disclosed for effectively displaying database records on a device having a display area that is small compared to the underlying data being represented. A simulated catalogue is displayed with cards associated with database records. Detailed information is presented for a record on a card obscuring information related to other records. A user is allowed to swipe on the catalogue causing simulated movement of the cards thereby displaying information associated with a database record previously obscured. The catalogue is moved with an initial velocity determined by the speed of swiping and decelerated based on a drag factor until it comes to a stop and displays information for the record reached. The ability to determine the final record displayed when the catalogue stops allows pre-fetching of the data associated with the record.

Claims

1. A computer-implemented method for graphically displaying database records on a display screen with limited display area, the method comprising:

displaying a first database record on a first face of a cube;

and

responsive to a user input, animating the display to rotate the cube;

determining a final record from the plurality of database records to display at a conclusion of the rotation before the rotation comes to the conclusion;

rendering an image of the cube displaying the final record before the rotation comes to the conclusion; and

responsive to the conclusion of the rotation, receiving the rendered image and displaying the rendered image on a second face of the cube.

2. The method of claim 1, wherein the user input is indicative of an input speed value and animating comprises displaying the cube rotating with a speed initialized to a first speed value determined based on the input speed value.

3. The method of claim 2, wherein the animating further comprises displaying the cube rotating with a second speed that is less than the first speed and greater than a predetermined minimum threshold, wherein the second speed value is determined by multiplying the first speed value by a predetermined drag value.

4. The method of claim 1, further comprising:

preloading the final record while the cube is displayed as rotating.

5. The method of claim 1, further comprising:

rendering an image of the second face of the cube for displaying the final record while the cube is displayed as rotating.

6. The method of claim 5, further comprising:

storing the image of the second face of the cube in a cache for retrieval prior to subsequently displaying the final record.

7. The method of claim 1, wherein the user input includes a swiping gesture across the display screen.

8. The method of claim 1, wherein the user input includes a swiping gesture across the display screen and an input speed value is determined based on the speed of swiping.

9. The method of claim 1, wherein the database records represent pages of report data.

10. A system for graphically displaying database records on a display screen with limited display area, the system comprising:

a computer processor; and

a computer-readable storage medium storing computer program modules configured to execute on the computer processor, the computer program modules comprising;

an input/output driver module configured to;

display a first database record on a first face of a cube;

responsive to a user input, animating the display to rotate the cube;

determine a final record from the plurality of database records to display at a conclusion of the rotation before the rotation comes to the conclusion;

render an image of the cube displaying the final record before the rotation comes to the conclusion; and

responsive to the conclusion of the rotation, receive the rendered image and displaying the rendered image on a second face of the cube.

11. The system of claim 10, wherein the user input is indicative of an input speed value and animating comprises displaying the cube rotating with a speed initialized to a first speed value determined based on the input speed value.

12. The system of claim 11, wherein the animating further comprises displaying the cube rotating with a second speed that is less than the first speed and greater than a predetermined minimum threshold, wherein the second speed value is determined by multiplying the first speed value by a predetermined drag value.

13. The system of claim 10, wherein the input/output driver module is further configured to:

preload the final record while the cube is displayed as rotating.

14. The system of claim 10, wherein the input/output driver module is further configured to:

render an image of the second face of the cube for displaying the final record while the cube is displayed as rotating.

15. The system of claim 14, wherein the input/output driver module is further configured to:

store the image of the second face of the cube in a cache for retrieval prior to subsequently displaying the final record.

16. The system of claim 14, wherein the user input includes a swiping gesture across the display screen, and wherein the input/output driver module is configured to determine an input speed value based on the speed of swiping.

17. A computer program product having a non-transitory computer-readable storage medium storing computer-executable code for graphically displaying database records on a display screen with limited display area, the code comprising:

an input/output driver module configured to;

display a first database record on a first face of a cube;

responsive to a user input, animating the display to rotate the cube;

determine a final record from the plurality of database records to display at a conclusion of the rotation before the rotation comes to the conclusion;

render an image of the cube displaying the final record before the rotation comes to the conclusion; and

responsive to the conclusion of the rotation, receive the rendered image and displaying the rendered image on a second face of the cube.

18. The computer program product of claim 17, wherein the input/output driver module is further configured to:

preload the final record while the cube is displayed as rotating.

19. The computer program product of claim 17, wherein the input/output driver module is further configured to:

render an image of the second face of the cube for displaying the final record while the cube is displayed as rotating.

20. The computer program product of claim 19, wherein the input/output driver module is further configured to:

store the image of the second face of the cube in a cache for retrieval prior to subsequently displaying the final record.
