Structural Analysis Diagrams Types and Elements

Types of Structural Analysis Diagrams

• Block Diagrams: Represent systems as interconnected blocks, showing inputs, processes, and outputs.
• Flowcharts: Illustrate step-by-step procedures, decision-making processes, and logic flows.
• Nassi-Schneiderman Diagrams: Visualize algorithms and programming logic using a sequence of connected boxes.

Elements of Structural Analysis Diagrams

• Entities: Objects or concepts being modeled, represented as boxes or rectangles.
• Attributes: Characteristics or properties of entities, listed inside entity boxes.
• Relationships: Connections between entities, represented by lines or arrows.

Notations and Symbols

• Unified Modeling Language (UML): Standard notation for software design and modeling.
• Entity-Relationship Diagrams (ERDs): Use rectangles, diamonds, and lines to represent entities, attributes, and relationships.
• BPMN (Business Process Model and Notation): Standard for business process modeling and workflow representation.

Purposes of Structural Analysis Diagrams

• Communication: Simplify complex systems and facilitate understanding among stakeholders.
• Analysis: Break down systems into manageable components for analysis and improvement.
• Design: Visualize and plan system architectures, software designs, and business processes.

Benefits of Structural Analysis Diagrams

• Improved understanding: Clarify complex systems and relationships.
• Enhanced communication: Facilitate stakeholder understanding and collaboration.
• Better design: Support informed design decisions and system optimization.
