+`yottob` is a Flask-based web application for processing YouTube RSS feeds with SQLAlchemy ORM persistence. The project provides both a REST API and CLI interface for fetching and parsing YouTube channel feeds, with filtering logic to exclude YouTube Shorts.

 ## Architecture
 
-The codebase follows a clean separation between business logic and web server:
+The codebase follows a clean layered architecture with separation of concerns:
+
+### Database Layer
+**`models.py`** - SQLAlchemy ORM models
+- `Base`: Declarative base for all models
+- `Channel`: Stores YouTube channel metadata (channel_id, title, link, last_fetched)
+- `VideoEntry`: Stores individual video entries with foreign key to Channel
+- Relationships: One Channel has many VideoEntry records
+
+**`database.py`** - Database configuration and session management
+- `DATABASE_URL`: SQLite database location (yottob.db)
+- `engine`: SQLAlchemy engine instance
+- `init_db()`: Creates all tables
+- `get_db_session()`: Context manager for database sessions
 
 ### Core Logic Layer
 **`feed_parser.py`** - Reusable YouTube feed parsing module
 - `YouTubeFeedParser`: Main parser class that encapsulates channel-specific logic
-- `FeedEntry`: Data model for individual feed entries
+- `FeedEntry`: In-memory data model for feed entries
+- `fetch_feed()`: Fetches and parses RSS feeds
+- `save_to_db()`: Persists feed data to database with upsert logic
 - Independent of Flask - can be imported and used in any Python context
 
 ### Web Server Layer
 **`main.py`** - Flask application and routes
-- `app`: Flask application instance (main.py:7)
-- `index()`: Homepage route handler (main.py:14)
-- `get_feed()`: REST API endpoint (main.py:20) that uses `YouTubeFeedParser`
-- `main()`: CLI entry point for testing (main.py:42)
+- `app`: Flask application instance (main.py:9)
+- Database initialization on startup (main.py:16)
+- `index()`: Homepage route handler (main.py:20)
+- `get_feed()`: REST API endpoint (main.py:26) that fetches and saves to DB
+- `get_channels()`: Lists all tracked channels (main.py:59)

+## Database Migrations
+
+This project uses Alembic for database schema migrations.
+
+**Create a new migration after model changes:**
+```bash
+source .venv/bin/activate && alembic revision --autogenerate -m "Description of changes"
+```
+
+**Apply migrations:**
+```bash
+source .venv/bin/activate && alembic upgrade head
+```
+
+**View migration history:**
+```bash
+source .venv/bin/activate && alembic history
+```
+
+**Rollback to previous version:**
+```bash
+source .venv/bin/activate && alembic downgrade -1
+```
+
+**Migration files location:** `alembic/versions/`
+
+**Important notes:**
+- Always review auto-generated migrations before applying
+- The database is automatically initialized on Flask app startup via `init_db()`
+- Migration configuration is in `alembic.ini` and `alembic/env.py`
+- Models are imported in `alembic/env.py` for autogenerate support
+
+## Database Schema
+
+**channels table:**
+- `id`: Primary key
+- `channel_id`: YouTube channel ID (unique, indexed)
+- `title`: Channel title
+- `link`: Channel URL
+- `last_fetched`: Timestamp of last feed fetch
+
+**video_entries table:**
+- `id`: Primary key
+- `channel_id`: Foreign key to channels.id
+- `title`: Video title
+- `link`: Video URL (unique)
+- `created_at`: Timestamp when video was first recorded
+- Index: `idx_channel_created` on (channel_id, created_at) for fast queries
+
 ## Dependencies
 
 - **Flask 3.1.2+**: Web framework
 - **feedparser 6.0.12+**: RSS/Atom feed parsing
+- **SQLAlchemy 2.0.0+**: ORM for database operations
+- **Alembic 1.13.0+**: Database migration tool
 - **Python 3.14+**: Required runtime version
