Modeling Techniques
UML diagrams serve as essential tools for Business Analysts, providing visual representations of software systems that enhance communication and understanding among stakeholders. Key types of UML diagrams include Use Case Diagrams, Activity Diagrams, and Sequence Diagrams, each serving distinct purposes in modeling system functionality, workflows, and interactions over time. By effectively utilizing these diagrams, BAs can streamline process analysis and improve the clarity of system requirements.

What we have learnt
- UML diagrams are critical for visualizing software systems.
- Use Case Diagrams capture the functional interactions between users and the system.
- Activity Diagrams represent the flow of activities within a business process.
- Sequence Diagrams illustrate interactions between objects over time, focusing on order and message exchanges.
Key Concepts
- -- Use Case Diagrams
- Diagrams that represent high-level functional interactions between actors and the system, defining system scope and functionality.
- -- Activity Diagrams
- Diagrams that depict the flow of activities within a business process, showing sequential, parallel, and conditional flows.
- -- Sequence Diagrams
- Diagrams that describe the interaction between objects and components over time, emphasizing the order of message exchanges.
- -- Actors
- External users or systems that interact with the application within Use Case Diagrams.
- -- Swimlanes
- Visual elements in Activity Diagrams that represent the responsibilities of different actors or departments.
