Requirements Modeling with Dynamic Views

When developing a system, understanding requirements is essential. It’s like constructing a house — the blueprint must come first. I’ve learned that dynamic views in requirements modeling are powerful for illustrating how a system behaves over time. They reveal interactions, processes, and reactions between components. By using dynamic views, we gain a deeper understanding of system logic and performance. Let’s explore how this approach brings models to life and connects design with real behavior.

Understanding UML Generalization and Specialization

UML (Unified Modeling Language) is a powerful tool for modeling complex systems, and one of its most useful concepts is UML generalization and specialization. These ideas help organize and simplify relationships by showing how broader classes can share common traits with more specific ones. In this article, I’ll explain how UML generalization and specialization work in practice, using clear examples and a real business case to make these concepts easy to understand and apply.

What are UML Aggregation and Composition?

As a requirements engineer, I often explore the depth of UML and how it visualizes system connections. Understanding what are UML aggregation and composition is essential for modeling effective “part/whole” relationships. These concepts show how one class can include or depend on another, helping us design systems with clear structure and hierarchy. In this article, I’ll explain what are UML aggregation and composition and how they make complex systems easier to understand.
