Mobility is a gem for storing and retrieving translations as attributes on a class. These translations could be the content of blog posts, captions on images, tags on bookmarks, or anything else you might want to store in different languages.
Storage of translations is handled by customizable “backends” which encapsulate different storage strategies. The default, preferred way to store translations is to put them all in a set of two shared tables, but many alternatives are also supported, including [translatable columns](http://dejimata.com/2017/3/3/translating-with-mobility#strategy-1) and [model translation tables](http://dejimata.com/2017/3/3/translating-with-mobility#strategy-2), as well as database-specific storage solutions such as [jsonb](https://www.postgresql.org/docs/current/static/datatype-json.html ) and [Hstore](https://www.postgresql.org/docs/current/static/hstore.html) (for PostgreSQL).
