# Locales

Locales are the language or languages presented to an InForm user in the user interface.

- Product Locale—The language(s)—English or Japanese—of the product user interface components: menus, controls, commands, system screen labels, error messages, and so on. Oracle creates product locales.
- Study Locale—The language(s) in which study metadata are designed using the Central Designer application. This includes CRFs and related study design labels, such as visit names, CRF (form) names, section labels, CRF questions, item control labels, auto-query text, and so on. A study may contain multiple study locales.
- Study Data Locale—The language in which study data, most significantly text, is entered and stored.
- Review Schema Locale—The language, set automatically during installation, in which data appears in the Data Viewer. For information on how to change the Review Schema Locale, see the Installation Guide.

Note: Messages in the InForm application are generated from a number of sources, including the operating system and the product itself. Because the product locale in the InForm application may be set to a language other than that of the user's operating system, it is possible for the user to see messages generated from the InForm application in mixed languages.
