Localizing Derby

Derby offers support for locales.

The word locale in the Java platform refers to an instance of a class that identifies a particular combination of language and region. If a Java class varies its behavior according to locale, it is said to be locale-sensitive. Derby provides some support for locales for databases and for other components, such as the tools and the installer.

Derby also provides a feature to support databases in many different languages, a feature which is independent of a particular locale. When you create or upgrade a database, you can use the territory=ll_CC attribute to associate a non-default locale with the database. For information on how to use the territory=ll_CC attribute, see the Derby Reference Manual.

• SQL parser support for Unicode
  To support users in many different languages, Derby's SQL parser understands all Unicode characters and allows any Unicode character or number to be used in an identifier.

  A character set is a set of symbols and encodings. Character data types are represented as Unicode 2.0 sequences in Derby. Collation defines how character data is sorted.
