Warnier Diagram enables the analyst to represent

A Warnier Diagram is a graphical tool used in structured analysis to depict the hierarchical structure of data and information. It visually represents how complex data is decomposed into smaller, manageable components using nested brackets. This makes Option B (Information Hierarchy) the correct choice because the diagram's primary purpose is to show logical organization and relationships within data structures.\nOption A (Class structure) is incorrect because class diagrams are typically represented using UML, not Warnier Diagrams. Option C (Data Flow) is incorrect as Data Flow Diagrams (DFDs) are used to show how data moves through a system, whereas Warnier Diagrams focus on static structure. Option D (State Transition) is incorrect because state transition diagrams illustrate system behavior and changes over time, which is outside the scope of Warnier Diagrams. Therefore, understanding that Warnier Diagrams focus on logical decomposition and hierarchy is key to selecting the right answer.
