STATE CHART DIAGRAM
Here's an example of a state chart diagram representing the states and transitions in a login module
system:
```
+----------------------------+
| Login Module System |
+----------------------------+
| User Provides Credentials
+----------------------------+
| Idle State |
+----------------------------+
| Validate Credentials
+----------------------------+
| Credentials Valid State |
+----------------------------+
| User Authentication
+----------------------------+
| Authenticated State |
+----------------------------+
| User Performs Actions

```
In this state chart diagram, the login module system goes through various states and transitions
during the login and logout process:
1. Idle State: Represents the initial state of the login module system. It is waiting for the user to
provide their credentials.
2. Credentials Valid State: Represents the state when the user-provided credentials are validated
and found to be valid.
3. Authenticated State: Represents the state when the user is successfully authenticated. They are
granted access to the system.
4. Active State: Represents the state when the user is logged in and actively using the system. They
can perform various actions and operations.
5. Logged Out State: Represents the state when the user logs out of the system. They are no longer
authenticated or active.
The transitions between states occur as follows:
- User Provides Credentials: Transition from the Idle State to the Credentials Valid State when the
user provides their login credentials.
- Validate Credentials: Transition from the Credentials Valid State to the Authenticated State when
the provided credentials are validated and found to be valid.

- User Authentication: Transition from the Authenticated State to the Active State when the user is
successfully authenticated.
- User Performs Actions: Transition from the Active State to itself when the user performs various
actions within the system.
- User Logs Out: Transition from the Active State to the Logged Out State when the user chooses to
log out of the system.
