"""Database package for the Aniworld web application.

This package provides SQLAlchemy models, database connection management,
and session handling for persistent storage.

Modules:
    - models: SQLAlchemy ORM models for anime series, episodes, download queue, and sessions
    - connection: Database engine and session factory configuration
    - base: Base class for all SQLAlchemy models

Usage:
    from src.server.database import get_db_session, init_db
    
    # Initialize database on application startup
    init_db()
    
    # Use in FastAPI endpoints
    @app.get("/anime")
    async def get_anime(db: AsyncSession = Depends(get_db_session)):
        result = await db.execute(select(AnimeSeries))
        return result.scalars().all()
