Create new user sequence diagram

Here is a new user sequence diagram:

Sequence Diagram: User Registration

Participants:

• User: The person using the system to register
• System: The software application that handles user registration
• Database: The database that stores user information

Sequence:

1. User initiates the registration process by clicking on the "Register" button.
2. System displays a registration form to User, asking for the following information:
   • Username
   • Email address
   • Password
   • Confirm password
   • First name
   • Last name
3. User fills out the registration form and clicks on the "Submit" button.
4. System validates the input data:
   • Checks if the username is unique (i.e., not already taken by another user)
   • Verifies the email address format
   • Checks if the password and confirm password match
   • Checks if the first name and last name are not empty
5. System sends a request to Database to create a new user account with the provided information.
6. Database creates a new user account and returns a confirmation message to System.
7. System displays a success message to User, indicating that the registration was successful.
8. System logs User in automatically, allowing them to access the system.

Notes:

• The sequence diagram assumes that the system has already been configured to use a secure password hashing algorithm and that the database is designed to store user information securely.
• The diagram does not show the actual database schema or the specific validation rules used by the system. These details would be included in a more detailed design document or code implementation.
• The sequence diagram is a high-level representation of the user registration process and can be used as a starting point for designing the system's architecture and user interface.
