This client-server UML sequence diagram shows the authentication and data retrieval process between a client, server, and database. It begins with the client sending an authentication request. The server validates the credentials with the database. If authentication succeeds, the client can request data. The server queries the database to fetch it. If data is found, it’s sent back. If not found, an error message is returned. If invalid credentials, the authentication fails, and an error is sent to the client. This diagram illustrates success, alternative, and failure scenarios for seamless communication.
