Abstract

A unique database architecture and applications for enabling large amounts of text and graphic images to be displayed on handheld computing devices such as personal digital assistants, smart phones, and other wireless personal computer platforms is disclosed. The unique database architecture and applications provide a user friendly interface for creating and storing text and graphic or image content using a standard personal computer in which the data is converted, compressed, manipulated and stored into the unique database architecture. The converted and compressed data can be loaded onto a handheld computing device to provide a tool for viewing the text and image content in a small portable form. The unique database architecture and applications are particularly useful for providing mobile content such as reference materials, training materials, question and answer information, entertainment content, and other content based resources.

Claims

1. A database architecture for handheld computer devices comprising:

a root node for providing information about a database;

a plurality of leaf nodes for storing a plurality of content;

at least one link node for linking said root node to at least one end node or to another of said at least one link node;

wherein said end node connects to at least one of said plurality of leaf nodes.

2. The database architecture of claim 1, wherein said root node, said plurality of leaf nodes, said at least one link node, and said at least one end node are stored as records within said database.

3. The database architecture of claim 1, wherein said plurality of leaf nodes comprises at least one Question-Answer-Fact (QAF) leaf node.

4. The database architecture of claim 1, wherein said plurality of leaf nodes comprises at least one Fact leaf node.

5. The database architecture of claim 1, wherein said plurality of leaf nodes comprises at least one Bitmap leaf node.

6. The database architecture of claim 1, wherein said plurality of content comprises text content.

7. The database architecture of claim 1, wherein said plurality of content comprises image content.

8. The database architecture of claim 1, wherein said plurality of content contains reference material.

9. The database architecture of claim 1, wherein said plurality of content contains training material.

10. The database architecture of claim 1, wherein said plurality of content contains testing material.

11. A database architecture system for creating content for viewing on handheld computing devices comprising:

a database architecture comprising;

a root node for providing information about a database;

a plurality of leaf nodes for storing a plurality of content;

at least one link node for linking said root node to at least one end node or to another of said at least one link node;

wherein said end node connects to at least one of said plurality of leaf nodes;

a first software program for entering and editing said plurality of content within said database architecture; and

a second software program for viewing said plurality of content on a handheld computing device.

12. The database architecture system of claim 11 wherein said first software program is run on a personal computer.

13. The database architecture system of claim 11 wherein said second software program is run on said handheld computer device.

14. The database architecture system of claim 11 wherein said plurality of content comprises text content.

15. The database architecture system of claim 11 wherein said plurality of content comprises image content.

16. The database architecture system of claim 11 wherein said plurality of content contains reference material.

17. The database architecture system of claim 11 wherein said plurality of content contains training material.

18. The database architecture system of claim 11 wherein said plurality of content contains testing material.

20. The method of claim 19 further comprising the step of:

compressing said content to fit on a display of said handheld computing device.

21. The method of claim 19 wherein said processing further comprises the steps of:

determining the type of said handheld computing device; and

converting said content to meet the determined type of said handheld computing device.

22. The method of claim 21, further comprising the steps of:

determining the type of said content, wherein said content comprises text content and image content; and

converting said image content to a color scheme of said handheld computing device.

19. A method of providing content on a handheld computing device comprising the steps of:

entering a plurality of content through a first program into a database;

said database having a database architecture comprising;

a root node for providing information about a database;

a plurality of leaf nodes for storing said plurality of content;

at least one link node for linking said root node to at least one end node or to another of said at least one link node;

wherein said end node connects to at least one of said plurality of leaf nodes;

processing said content to said handheld computing device; and

viewing said content through a second program run on said handheld computing device.
