    By showing the interactions between actors (users or external systems) and the system itself, use case diagrams are able to accurately represent the functional requirements of a system. For the purpose of drawing thorough use case diagrams, it is crucial to comprehend how to recognize actors, use cases, and their connections. Use case diagrams assist you in visualizing the system from the viewpoint of the user and in recognizing the various ways in which users engage with the system. You can effectively communicate the functionalities of the system and the functions played by various actors by accurately representing use cases and their relationships with actors. It's crucial to establish associations and dependencies between actors and use cases, identify primary and secondary actors, and define use cases with precise names.

    1.3 Sequence Diagrams

    Sequence diagrams display the interactions between objects over time in order to demonstrate the dynamic behavior of a system. They aid in the visualization of communication patterns and the sequence of interactions between objects. Understanding the sequence of operations and displaying the system's behavior requires the ability to create sequence diagrams. With the aid of sequence diagrams, you can determine the sequence in which objects interact with one another and the messages that are sent and received. You can effectively communicate the behavior of the system and comprehend the flow of control by accurately representing the sequence of events. In sequence diagrams, it's crucial to note the involved objects, their lifelines, and the messages that they communicate with one another. Additionally, accurate and meaningful sequence diagram creation depends on a thorough understanding of ideas like synchronous and asynchronous messages, branching, and looping.

    2. Planning and Analysis

    It's imperative to plan and analyze the requirements of the system you are modeling before beginning any UML assignment.
