What is the structure for a database that supports multiple languages?

edit

The structure for a database that supports multiple languages typically includes the following elements:

1. Tables: The database will have one or more tables that store the data relating to various aspects of the system. For example, if the database is for an e-commerce website, it might have tables for products, orders, users, and so on.

2. Columns: Within each table, there may be columns that contain data that needs to be localized. For example, the "Product" table might have columns for "Name," "Description," "Price," and so on. In a multilingual database, these columns would need to have multiple versions to support different languages.

3. Language codes: To support multiple languages, the database will need to include language codes that indicate which language version of a given column applies. For example, the "Name" column might have entries for "Product AEN" and "Product AFR" to indicate the English and French versions, respectively.

4. Translation tables: The database may also include tables that store translations for common terms or phrases. For example, there might be a table that maps "add to cart" to "ajouter au panier" for French-speaking users.

5. User preferences: Finally, the database may allow users to specify their preferred language, which can be used to display the appropriate version of the data.
