+# Database Migrations
+
+The backend uses **[Knex.js](https://knexjs.org/)** as the migration tool.  
+Migration state is tracked automatically in a `knex_migrations` table created by Knex on first run.
+
+## Configuration
+
+| Environment | Client | Connection |
+|-------------|--------|------------|
+| `development` | SQLite (`better-sqlite3`) | `./dev.db` or `DATABASE_URL` env var |
+| `test` | SQLite in-memory | `:memory:` |
+| `production` | PostgreSQL (`pg`) | `DATABASE_URL` env var (required) |
+
+Set `DATABASE_URL` in your `.env` file:
+
+```env
+# SQLite (dev)
+DATABASE_URL=./dev.db
+
+# PostgreSQL (production)
+DATABASE_URL=postgresql://user:password@host:5432/dbname
+```
+
+## Running migrations
+
+```bash
+# Apply all pending migrations
+npm run migrate
+
+# Roll back the most recent migration batch
+npm run migrate:rollback
+
+# Show applied / pending migration status
+npm run migrate:status
+```
+
+## Creating a new migration
+
+```bash
+npm run migrate:make -- <migration_name>
+# Example:
+npm run migrate:make -- add_location_to_assets
+```
+
+This generates a timestamped file in `backend/migrations/`.  
+Edit the generated file and implement `up` (apply) and `down` (rollback):
+
+```js
+export async function up(knex) {
+  await knex.schema.table('assets', (table) => {
+    table.string('location');
+  });
+}
+
+export async function down(knex) {
+  await knex.schema.table('assets', (table) => {
+    table.dropColumn('location');
+  });
+}
+```
+
+## Migration files
+
+| File | Description |
+|------|-------------|
+| `20260628000000_create_assets_table.js` | Creates the `assets` table with core columns |
+
+## How it works
+
+1. On first run, Knex creates a `knex_migrations` table to record which migrations have been applied and in which batch.
+2. `npm run migrate` runs all migrations that are not yet recorded in that table.
+3. `npm run migrate:rollback` reverts the last batch of migrations by calling their `down` functions.
+4. Each migration file exports an `up` and a `down` function — always implement both to support rollbacks.
+
+> **Tip for contributors:** every PR that changes the database schema must include a new migration file. Never edit an existing migration that has already been applied in production.
