Oracle7 Server NLS Architecture

The NLS architecture has two components: language-independent functions and language-dependent data. The former provides generic language-oriented features; the latter provides data required to operate these features for a specific language.

Because the language-dependent data is separate from the code, the operation of NLS functions is governed by data supplied at runtime. New languages can be added and language-specific application characteristics can be altered without requiring any code changes. This architecture also enables language-dependent features to be specified for each session.
