# Database

A database is required for storing your users and sessions. Lucia connects to your database via an adapter, which provides a set of basic, standardized querying methods that Lucia can use.

```ts
import { Lucia } from "lucia";
import { BetterSqlite3Adapter } from "@lucia-auth/adapter-sqlite";

const lucia = new Lucia(new BetterSqlite3Adapter(db));
```

See [`Adapter`](/reference/main/Adapter) for building your own adapters.
