UML Introduction

The UML (Unified Modeling Language) is a visual modeling language designed to provide a common language for the architecture, design, and implementation of complex software systems. It focuses on both structural and behavioral aspects.

Representing Classes in UML

To represent a class using UML, use lines to represent relationships between classes, instances, or components in a class diagram. UML requires the use of multiple lines or arrows to represent various functions and relationships. In this case, a dashed arrow with an open tip is used to connect a class to the desired interface.

Purpose of Class Diagrams

Class diagrams are one of the types of diagrams that can be displayed in a UML model. They describe various types of entities, their characteristics, and any relationships between these types.

Representing Classes

A rectangle represents a class in UML. By convention, the class name appears near the top of the rectangle and starts with a capital letter.

Writing Use Cases

Elements in use cases include:

  • Brief description: A short explanation of the use case.
  • Actor: The participants in the use case.
  • Preconditions: Conditions that must be met before the use case starts.
  • Basic Flow: The normal workflow in the system, also known as the "base flow" or "main scenario."

Understanding Use Cases

The term "use case" refers to a set of interactions between a user and a system that allow the user to achieve a goal or perform a task.

Purpose of Use Case Diagrams

Use case diagrams are a type of behavioral UML diagram that is often used to analyze a variety of systems. They allow for the visualization of the various roles present in a system and how these roles interact with the system as a whole.

Non-Functional Requirements

Non-functional requirements are software characteristics that the client does not explicitly request but have a significant impact on the work of developers. They describe how the system performs certain tasks, rather than what tasks it performs.

Defining Requirements

A requirement, derived from the Latin word "requisitus" meaning required, is a quality that is requested or desired for a product. The goal of a requirements document is to provide an organized description of all desired properties.
