128. systems analysis: mapping data flow (ks4)
Master systems analysis by creating data flow diagrams, mapping how information moves through a complex system to identify bottlenecks and improve efficiency.
Before developers write complex code for a new system, they need to understand exactly how information will travel through it. Where does the data start, and where does it end up? We are going to master systems analysis by drawing Data Flow Diagrams (DFDs). You will learn how to visually map the journey of information, spotting bottlenecks and designing highly efficient digital systems.
