Abstract

A data dependency path calculator for a semantic search engine is provided. A body of semantically related data is modeled according to a semantic data model. A user is presented a list of data elements from which they may select desired data elements. The system automatically calculates all of the possible paths through the database that may be used to retrieve meaningful data based on the selected data elements. The available data dependency paths are returned to the user for selection. The system further provides a type of data permission that allows restricted data elements to be used as a pass-through data element for relating, connecting and retrieving non-restricted data. Thus, a user can use restricted data to create data dependency paths to retrieve meaningful data.

Claims

1. A method for performing rapid application development, comprising:

a) creating the data dependency path based on a data model representing units of meaning and their relationships; and

b) creating an input/output user interface based on the data dependency path.

2. The method of claim 1, wherein step b) comprises:

receiving user input selecting the data dependency path;

receiving user input selecting a plurality of data items within the data dependency path; and

generating the user interface comprising the selected plurality of data items.

3. The method of claim 2, wherein receiving user input selecting the plurality of data items comprises receiving user input indicative of the user selecting each selected data item from a first window to a second window, said first window displaying the data dependency path, and said second window comprising a user interface palette;

and

wherein generating the user interface comprises creating a data entry field for each selected data item dragged and dropped into the second window.

4. The method of claim 3, wherein step b) further comprises receiving user input renaming one or more of the plurality of selected data fields.

5. The method of claim 1, further comprising:

c) receiving input via the user interface; and

d) populating a database using the data model with the received input when the user input is not already present in the database.

6. The method of claim 3, further comprising:

c) receiving a user query based on the user interface; and

d) displaying query results via the user interface.

7. The method of claim 6, wherein step c) comprises:

receiving user input of a first value into a first data entry field; and

determining whether the first value already exists in a record of a database using the data model, and

wherein step d) comprises retrieving the record and displaying record information to the user via the user interface.

8. The method of claim 7, further comprising:

e) receiving user input modifying displayed record information; and

f) modifying the database based on the user input.

9. The method of claim 1, wherein step a) comprises:

analyzing the data model stored to identify a data view of the data model, said data model comprising a propositional structure representing a grammar having a plurality of parts of speech, said propositional structure having 28 predefined data relations comprising identifiers, modifiers, and descriptors related using predefined logical operators;

automatically creating the data dependency path based on the identified data view; and

storing data identifying the data dependency path.

10. The method of claim 9, wherein the data view comprises data located in a plurality of databases.

11. The method of claim 5, further comprising validating the user input based on the data dependency path.

12. The method of claim 6, further comprising exporting the query results using a data protocol.

13. One or more computer readable media storing computer executable instructions to perform a method for performing rapid application development, said method comprising:

a) creating the data dependency path based on a data model representing units of meaning and their relationships; and

b) creating an input/output user interface based on the data dependency path.

14. The computer readable media of claim 13, wherein step b) comprises:

receiving user input selecting the data dependency path;

receiving user input selecting a plurality of data items within the data dependency path; and

generating the user interface comprising the selected plurality of data items.

15. The computer readable media of claim 14, wherein receiving user input selecting the plurality of data items comprises receiving user input indicative of the user selecting each selected data item from a first window to a second window, said first window displaying the data dependency path, and said second window comprising a user interface palette;

and

wherein generating the user interface comprises creating a data entry field for each selected data item dragged and dropped into the second window.

16. The computer readable media of claim 15, wherein step b) further comprises receiving user input renaming one or more of the plurality of selected data fields.

17. The computer readable media of claim 13, said method further comprising:

c) receiving input via the user interface; and

d) populating a database using the data model with the received input when the user input is not already present in the database.

18. The computer readable media of claim 15, said method further comprising:

c) receiving a user query based on the user interface; and

d) displaying query results via the user interface.

19. The computer readable media of claim 18, wherein step c) comprises:

receiving user input of a first value into a first data entry field; and

determining whether the first value already exists in a record of a database using the data model, and

wherein step d) comprises retrieving the record and displaying record information to the user via the user interface.

20. The computer readable media of claim 19, said method further comprising:

e) receiving user input modifying displayed record information; and

f) modifying the database based on the user input.

21. The computer readable media of claim 13, wherein step a) comprises:

analyzing the data model stored to identify a data view of the data model, said data model comprising a propositional structure representing a grammar having a plurality of parts of speech, said propositional structure having 28 predefined data relations comprising identifiers, modifiers, and descriptors related using predefined logical operators;

automatically creating the data dependency path based on the identified data view; and

storing data identifying the data dependency path.

22. The computer readable media of claim 21, wherein the data view comprises data located in a plurality of databases.

23. The computer readable media of claim 17, said method further comprising validating the user input based on the data dependency path.

24. The computer readable media of claim 18, said method further comprising exporting the query results using a data protocol.
