The new version of SQLite has added support for WinRT and Metro style applications for Windows 8, and Windows 8 Mobile will also support the lightweight database.

SQLite is an in-process library that implements a self-contained, serverless, transactional SQL database engine. It doesn’t have a separate server process, and it reads and writes directly to ordinary disk files.

The entire SQL database with multiple tables, indexes, triggers, and views, is contained in a single disk file. SQLite comes as a very small programming library using less than 275K, but you don’t get a client, just the engine that you have to wrap as a WinRT component in order to make use of it in apps written in .NET or JavaScript.

To use the latest version from .NET, there’s a LINQ wrapper in SQLite-Net (https:// github.com/praeclarum/sqlite-net) that avoids the need for you to write your own wrapper.

If you’re writing in JavaScript, SQLite3-WinRT (https://github.com/doo/SQLite3-WinRT) provides a suitable wrapper.
