# Tools and localization

The Derby tools provide support for common localization features such as localized message files and GUI, locale-appropriate formatting of data, codesets, unicode identifiers and data, and database locales.

For general information about localizing Derby systems, see the Derby Developer's Guide.

- About locales
  The Derby documentation refers to three locales.
- Database locale
  To specify a database locale, use the territory=ll_CC attribute on the URL connection when creating the database.
- Specifying an alternate codeset
  You can specify an alternate codeset for your tool session.
- Formatting display of locale-sensitive data
  To display dates, timestamps, numbers, and times in the format of the ij Session locale, use the LocalizedDisplay command.
