DFD Guide: Event-Driven Process Visualization Using Data Flow Diagrams

In modern software architecture, systems rarely operate in a linear sequence. Instead, they respond to stimuli, changes in state, or incoming signals. This paradigm is known as Event-Driven Architecture (EDA).…

OOAD Guide: Evaluating Design Quality in Academic Projects

In the field of Object-Oriented Analysis and Design (OOAD), the distinction between code that simply functions and code that is engineered for longevity is often defined by design quality. Academic…
