How do Session and Global Session differ in the context of software systems?

In the context of software systems, especially in Java and web development, Session usually refers to a user session — a temporary context that stores data about a specific user's interaction with the application over a certain period (e.g., authentication data, shopping cart, etc.).

Global Session — a broader term that can mean a session available globally to all users or system components, or a session that combines multiple local sessions. In some systems, Global Session is used for coordinating transactions or managing state between different modules or services.

Example:

• Session: data of a specific user on a website.
• Global Session: a common context for all users or for several related services.

Thus, the main difference is the scope and duration of the session: Session is local and individual, while Global Session is shared and more long-term.
