Abstract

The present invention provides the ability to internationalize a database application by providing a capability to create and maintain related international records. Data items can be stored in a base language with accompanying related copies of the data items represented in multiple languages and/or currencies. Application users can specify a preferred language. When data items are retrieved from a database, and when the user'"'"'s language preference is not the same as the base language, language-dependent data items are retrieved from the related language records. When a related language record does not exist, or the preferred language is equal to the base language, the data items are retrieved from the base language records. Delete, Insert and Update operations can be performed on base language records, related language records or both.

Claims

1. A method of providing multilingual versions of data items in a computer database system comprising the steps of:

identifying a base language in which language-independent data items and language-dependent data items can be represented in said computer system;

identifying a preferred language in which said language-dependent data items and said language-independent data items can be represented;

storing a base language version of said language-dependent data items and language-independent data items in a base language record;

creating a related language version of said language-dependent data items when a preferred language version of said language-dependent data items is created;

accessing in said base language record said language-independent data items;

accessing in said base language record said language-dependent and said language-independent data items when said base language is the same as said preferred language;

accessing in said base language record said language-dependent data when said related language version does not exist for said preferred language; and

accessing in said related language record said language-dependent data items when said related language version does exist in said preferred language.

2. The method of claim 1 wherein said accessing of said base language record and said preferred language record is a data retrieval operation.

3. The method of claim 1 wherein said accessing of said base language record and said preferred language record is an insert operation.

4. The method of claim 1 wherein said accessing of said base language record and said preferred language record is a delete operation.

5. The method of claim 1 wherein said accessing of said base language record and said preferred language record is an update operation.

6. A method of linking multilingual versions of data in a computerized database comprising the steps of:

defining a first table to contain base language records, said base language records storing base language versions of language-independent data items and language-dependent data items;

defining a second table to contain multilingual records, said multilingual records storing multilingual versions of language-dependent data items;

defining a linkage between said second table and said first table, said linkage identifies said second table to contain multilingual versions of said base language records.

7. The method of claim 6 wherein said first table comprises a relational database.

8. The method of claim 6 wherein said second table comprises a relational database.

9. The method of claim 6 further comprising access means to said first and second tables.

10. The method of claim 9 wherein said access means providing a data retrieval operation.

11. The method of claim 9 wherein said access means providing an insert operation.

12. The method of claim 9 wherein said access means providing a delete operation.

13. The method of claim 9 wherein said access means providing an update operation.
