Localizing Oracle BI Data

Copyright 2008, Oracle. All rights reserved.15 - 2

Objective

After completing this lesson, you should be able to localize

Oracle BI data to support multilingual environments.


Business Challenges and Solution

Challenges:

Companies require multilingual support for global deployments of Oracle BI.

Users need to make decisions based on applications and data presented in their own language.

Solution:

Add multilingual support to Oracle BI.


Oracle BI Multilingual Support

Requires three types of configurations:

Repository metadata, such as presentation folders

Database data, such as product names

Report and dashboard metadata, such as chart labels

Focus of last lesson

Focus of this lesson

Covered in a separate course


Required Translation Tables

Data translation requires two tables:

List of values (LOV) language translation table

Provides functionality similar to metadata translation table

Available language table

Provides list of available user data languages


ABC Example

Translate ABC product-type data from English to French.


Steps for Localizing Data

1. Create a language translation table.

2. Create an available language table.

3. Import tables to the Physical layer.

4. Create a session variable initialization block.

5. Create a language translation table alias.

6. Create physical joins.

7. Map the logical table source.

8. Create column mapping.

9. Apply a WHERE filter.

10.Verify the results.


1. Create a Language Translation Table

This table contains required columns and the language value

translations.

Language-

independent code (LIC): Identifies

which record is being

translated

VAL: Translated data

that is displayed to

the user

LANG_ID: Code

that identifies the

language of the row

TYPE: A categorization for

a set of values


2. Create an Available Language Table

This table stores a list of languages available for querying

against the data.

LANGUAGE_EXTENSION:

identifies language variations

based on country or region

LANG_ID: identifies the

language of the row

LANGUAGE: identifies the

language name


3. Import Tables to the Physical Layer

Use known techniques to import language tables to the

Physical layer of the repository.

Language translation table

Available language table


4. Create a Session Variable Initialization Block

Create a session variable initialization block to check whether

the language selected by the user is in the language table.

Checks whether the user

language preference stored in WEBLANGUAGE is in the

D1_LANG table

Language default if the preferred language is not found in the D1_LANG table

Session variable


5. Create a Language Translation Table Alias

Create an alias of the LOV table for each column that needs to

be translated.

Set the alias name to the

name of the column to be

translated.


6. Create Physical Joins

Create a join between the product dimension and the alias for

the column translation.

Dimension table

column to be

translated joins to LIC in alias table.

Join finds all

translations in

alias table for a

given item type.


7. Map the Logical Table Source

Map an existing logical table source to the alias.

Alias table


8. Create Column Mapping

Modify the Type field to map to the VAL column in the ItemType

(D1_LOV_D) alias.


9. Apply a WHERE Filter

To the logical table source, apply a WHERE filter that:

Searches in the alias table for records that have the

same language ID as

specified in the language

initialization block

Identifies the set of records in the alias table that are of

the ABC Product Type

category


10. Verify the Results

Run a query in Answers and verify that the expected results are returned.

Check the log file and verify that the VAL column is accessed with the expected WHERE clause.


Summary

In this lesson, you should have learned how to localize Oracle

BI data to support multilingual environments.


Practice 15-1 Overview:

Localizing Oracle BI Data

In this practice, you localize product type data from English to

French.
