Study Notes
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.
