Abstract

The invention relates to a method for querying a database with database contents that have a database structure. The query is made in a query structure, which differs from the database structure in that the query structure and the database structure reference a standard structure, and the reference logic is at least partially transmitted together with the query and/or is at least partially present in the database.

Claims

1. Method for querying a database with database contents with a database structure comprising:

placing a query in a query structure that differs from the database structure in that the query structure and the database structure;

at least partially transmitting a reference logic together with the query and/or is at least partially present in the database.

2. Method as claimed in claim 1, wherein the reference logic is stored in the database.

3. Method as claimed in claim 1, wherein the standard structure is described by standard descriptors (GD), and the query structure and the database structure are described by these standard descriptors (GD) and/or more special descriptors (HD), wherein these more special descriptors (HD) reference the standard descriptors (GD) via the reference logic.

4. Method as claimed in claim 3, wherein standard descriptors (GD) present in the query structure are compared with the standard descriptors (GD) of the database, wherein identical standard descriptors (GD) are evaluated for the query.

5. Method as claimed in claim 3, wherein the special descriptors (HD) present in the query structure are compared with the special descriptors (HD) of the database, wherein identical special descriptors (HD) are evaluated for the query.

6. Method as claimed in claim 5, wherein dissimilar special descriptors (HD) are reviewed to determine whether a computation logic is present in the database, so that a respective special descriptor (HD) of the database structure can be computed directly from the corresponding special descriptor (HD) of the query structure by means of the computation logic.

7. Method as claimed in claim 6, wherein the computation logic is stored in the database.

8. Method as claimed in claim 7, wherein, for dissimilar special descriptors (HD) for which no computation logic is present, a review is made to determine whether a reference logic to standard descriptors (GD) is at least partially present in the database.

9. Method as claimed in claim 7, wherein, for dissimilar special descriptors (HD) for which no computation logic and/or no reference logic is present, a review is made to determine whether the reference logic was transmitted together with the query.

10. Method as claimed in any one of claim 7, wherein atomic elements defining the information and/or link of a special descriptor (HD) are used as the computation logic.

11. Method as claimed in claim 10, wherein the atomic elements used are semantic, physical and linking atomic elements to define the semantic meaning, the physical memory structure, and the link between memory structure and semantics.

13. Computer readable media as claimed in claim 12, wherein the reference logic is stored in the database.

14. Computer readable media as claimed in claim 12, wherein the standard structure is described by standard descriptors (GD), and the query structure and the database structure are described by these standard descriptors (GD) and/or more special descriptors (HD), wherein these more special descriptors (HD) reference the standard descriptors (GD) via the reference logic.

15. Computer readable media as claimed in claim 14, wherein standard descriptors (GD) present in the query structure are compared with the standard descriptors (GD) of the database, wherein identical standard descriptors (GD) are evaluated for the query.

16. Computer readable media as claimed in claim 14, wherein the special descriptors (HD) present in the query structure are compared with the special descriptors (HD) of the database, wherein identical special descriptors (HD) are evaluated for the query.

17. Computer readable media as claimed in claim 16, wherein dissimilar special descriptors (HD) are reviewed to determine whether a computation logic is present in the database, so that a respective special descriptor (HD) of the database structure can be computed directly from the corresponding special descriptor (HD) of the query structure by means of the computation logic.

18. Computer readable media as claimed in claim 17, wherein the computation logic is stored in the database.

19. Computer readable media as claimed in claim 18, wherein, for dissimilar special descriptors (HD) for which no computation logic is present, a review is made to determine whether a reference logic to standard descriptors (GD) is at least partially present in the database.

20. Computer readable media as claimed in claim 18, wherein, for dissimilar special descriptors (HD) for which no computation logic and/or no reference logic is present, a review is made to determine whether the reference logic was transmitted together with the query.

21. Computer readable media as claimed in any one of claim 18, wherein atomic elements defining the information and/or link of a special descriptor (HD) are used as the computation logic.

22. Computer readable media as claimed in claim 21, wherein the atomic elements used are semantic, physical and linking atomic elements to define the semantic meaning, the physical memory structure, and the link between memory structure and semantics.

24. Method as claimed in claim 23, wherein the reference logic is stored in the database.

25. Method as claimed in claim 23, wherein the standard structure is described by standard descriptors (GD), and the query structure and the database structure are described by these standard descriptors (GD) and/or more special descriptors (HD), wherein these more special descriptors (HD) reference the standard descriptors (GD) via the reference logic.

26. Method as claimed in claim 25, wherein standard descriptors (GD) present in the query structure are compared with the standard descriptors (GD) of the database, wherein identical standard descriptors (GD) are evaluated for the query.

27. Method as claimed in claim 25, wherein the special descriptors (HD) present in the query structure are compared with the special descriptors (HD) of the database, wherein identical special descriptors (HD) are evaluated for the query.

28. Method as claimed in claim 27, wherein dissimilar special descriptors (HD) are reviewed to determine whether a computation logic is present in the database, so that a respective special descriptor (HD) of the database structure can be computed directly from the corresponding special descriptor (HD) of the query structure by means of the computation logic.

29. Method as claimed in claim 28, wherein the computation logic is stored in the database.

30. Method as claimed in claim 29, wherein, for dissimilar special descriptors (HD) for which no computation logic is present, a review is made to determine whether a reference logic to standard descriptors (GD) is at least partially present in the database.

31. Method as claimed in claim 29, wherein, for dissimilar special descriptors (HD) for which no computation logic and/or no reference logic is present, a review is made to determine whether the reference logic was transmitted together with the query.

32. Method as claimed in any one of claim 29, wherein atomic elements defining the information and/or link of a special descriptor (HD) are used as the computation logic.

33. Method as claimed in claim 32, wherein the atomic elements used are semantic, physical and linking atomic elements to define the semantic meaning, the physical memory structure, and the link between memory structure and semantics.

12. Computer readable media embodying a database structure to execute a method comprising:

placing a query in a query structure that differs from the database structure in that the query structure and the database structure reference a standard structure, and the reference logic is at least partially transmitted together with the query and/or is at least partially present in the database.

23. Computer readable media embodying a computer program to control a processor to perform a method comprising:

placing a query in a query structure that differs from the database structure in that the query structure and the database structure reference a standard structure, and the reference logic is at least partially transmitted together with the query and/or is at least partially present in the database.
