+```
+This code defines a `get_db` function that returns a generator function. The generator function creates a new SQLAlchemy session using `SessionLocal` from `app.api.db.database` and yields the session. After the session is used, it is closed in the `finally` block.
+The function signature `get_db() -> Generator[Session, None, None]` specifies that the function returns a generator that yields a `Session` object and does not receive or return any values.
+This function is typically used as a dependency in FastAPI routes to provide a database session for querying and modifying data.

+This code defines an `ActivityTrackerMiddleware` class that inherits from `BaseHTTPMiddleware`. The `dispatch` method is overridden to log the request method, URL, and processing time for each incoming request.
+Here's a breakdown of the code:
+This middleware can be added to the FastAPI application by including it in the list of middleware instances when creating the application instance.

+This code defines the necessary components for working with a SQLite database using SQLAlchemy in a FastAPI application named "blog_app".
+With this setup, you can define your database models by inheriting from `Base` and create database sessions using `SessionLocal`. The `engine` instance can be used for various database operations, such as creating tables or executing raw SQL queries.
