Are sessions stored in a database?
Session can either be memory, some database, simple files, or any other place you can come up with to store session data. If you project uses some database, you can configure your session store to use the same database, to avoid having another database on server just for the purpose of session store.
What is an Oracle DB session?
A session consists of every connection to the Oracle database by a user from a specific process. By tracking the number of Oracle sessions, we can track how busy a particular server is. This gives insight on how loaded an Oracle Database is. It also helps understand which users take more system resources.
What is a session in SQL?

The session data is more secure as a potential hacker must be able to log into the database before he can access anything. The use of multiple servers would not create a problem as all session data now resides in a single central place and is accessible by all servers.
Where does the session class store the session ID?
The Session class stores session information for each user as serialized (and optionally encrypted) data in a cookie. It can also store the session data in a database table for added security, as this permits the session ID in the user’s cookie to be matched against the stored session ID.
