Abstract

A comfortable method and device for searching databases are required. Thus, a database access concept including an interface descriptor is proposed. The interface descriptor may be a XML-file which describes interface categories and database access strategies. The database interface machine may comprise a standard category display method and a standard database access method. The database interface machine can use the definitions contained in the interface descriptor to set up a categorized interface to the database and to perform complete database searches.

Claims

1. Method for accessing a database having the steps of

presenting at least one category item defining a search criterion for said database,

selecting one or more of said at least one category item, and

searching in said database according to said selected one or more category items,

comprising

providing said at least one category item within interface descriptor means independent of the database.

2. Method according to claim 1, wherein said interface descriptor means is a software unit written in a standard programming language.

3. Method according to claim 2, wherein said standard programming language is XML.

4. Method according to claim 1, wherein a plurality of category items is provided and at least one category item of said plurality of category items includes one or more sub-category items.

5. Method according to claim 1, wherein said at least one category item includes combined search criteria.

6. Method according to claim 1, wherein the database is a metadata database.

7. Device for accessing a database having

display means for presenting at least one category item defining a search criterion for said database,

selecting means connected to said display means for selecting one or more of said at least one category item, and

searching means connected to said selecting means for searching in said database according to said selected one or more category items, and

interface descriptor means independent of the database for providing said at least one category item.

8. Device according to claim 7, wherein said interface descriptor means is a software unit written in a standard programming language.

9. Device according to claim 8, wherein said standard programming language is XML.

10. Device according to claim 7, wherein said external interface descriptor means includes a plurality of category items as search criteria and at least one category item of said plurality of category items includes one or more sub-category items.

11. Device according to claim 7, wherein said at least one category item includes combined search criteria.

12. Device according to claim 7, wherein said database is a metadata database.
