# Room.

Room is Android's persistence library over SQLite: entities, DAOs and queries declared in Kotlin with SQL verified at compile time, plus migrations and observable queries that emit when underlying data changes.

## Where Room fits on a long engagement.

Compile-time query verification is Room's main contribution. A malformed query, or one referencing a column that no longer exists, fails the build rather than throwing on a user's device. On an application where the schema changes regularly that removes a whole class of release-day incident.

Migrations are where Room applications go wrong in production. Every schema change needs a migration path, and destructive fallback — which silently wipes the database — is convenient in development and catastrophic if it reaches a release build. That single configuration line deserves more review attention than most of the code around it.

## What an assigned team does with Room.

Local data on a mobile device is genuinely permanent. Unlike a server database there is no operator to run a repair, so a bad migration reaching production means user data is gone and the only remedy is a store update.

That makes migration review a delivery gate rather than a nice-to-have, and it is exactly the sort of standard the assigned specialists are held to, as described in [how an assignment runs](https://azendo.co/how-it-works/).

## What we use Room for.

* Offline-capable applications Local storage that lets the app work without a connection and reconcile when one returns.
* Schema changes that do not lose data Explicit migrations reviewed before release, with destructive fallback kept out of release builds.
* Interfaces that update themselves Observable queries so a write in one place refreshes every screen reading it.

## How Room capacity is assigned.

Room work sits inside Android capacity, with migration safety treated as a release gate rather than assumed.

## Roles we assign Room for

* [Android Developer Mobile development](https://azendo.co/services/mobile-development/android-developer/)

## Service lines it sits in

* [Mobile development](https://azendo.co/services/mobile-development/)

Capacity is agreed as a committed monthly capacity across a discipline, not per skill.
