Locale Data on Demand

Oracle Database globalization support is implemented with the Oracle NLS Runtime Library (NLSRTL). The NLS RTL provides a comprehensive suite of language-independent functions that perform proper text and character processing and language-convention manipulations. Behavior of these functions for a specific language and territory is governed by a set of locale-specific data that is identified and loaded at run time.

The locale-specific data is structured as independent sets of data for each locale that Oracle Database supports. The data for a particular locale can be loaded independently of other locale data.

The advantages of this design are as follows:

You can manage memory consumption by choosing the set of locales that you need.
You can add and customize locale data for a specific locale without affecting other locales.

Oracle 全球化支持功能通过Oracle NLS Runtime Library (NLSRTL) 加以实施。

NLSRTL

National Language Support Runtime Library. This library is responsible for providing locale-independent algorithms for internationalization. The locale-specific information (that is, NLSDATA) is read by the NLSRTL library during run-time.

Globalization Support

To support multilingual application, Globalization Support functionality is required for cartridges and callouts. NLSRTL is a multiplatform, multilingual library current used in RDBMS and provides consistent Globalization Support behavior to all Oracle products.

Globalization Support basic services provide the following language and cultural sensitive functionality:
