Oracle 10g Overview of Designing a Global Internet
Application
There are two architectural models that must be
understood by DBAs and developers alike that are used either for
deploying a global web site or a global internet application,
depending on your globalization and business requirements. Which
model you choose to deploy affects how the internet application is
developed and how the application server is configured in the
middle-tier. Let's examine the two basic models.
Model
1: Multiple instances of monolingual internet applications
Monolingual internet applications support only
one locale in a single binary. The term locale refers to a national
language and the region in which the language is spoken. For
example, the primary language of the United States and Great Britain
is English. However, the two territories have different currencies
and different conventions for date formats. Not to mention various
usage differences. Therefore, the United States and Great Britain
are considered to be 2 different locales. As the old saying goes,
two countries divided by a common language.
Monolingual globalization support is suitable
for customers who want to support one locale per instance of the
application. This means that users need to have different entry
points to access the applications for different locales. This model
is only manageable if the number of supported locales is small.
Model
2: Single instance of a multilingual application
Multilingual internet applications support
multiple locales simultaneously in a single binary. This level of
globalization support is utilized by customers who need to support
several locales in a single internet application simultaneously. In
the multilingual model, users of different locale preferences use
the same entry point to access the application.
As you can imagine, developing and supporting
an application using the monolingual model is very different from
developing an application using the multilingual model. The Oracle
Globalization Services (OGS) consists of libraries that are used to
assist in the development of global applications using either
architectural model.
