Study Notes
Software Design Principles and Practices
- Software design is crucial.
- It's best understood as problem-solving.
- Abstraction is a key technique in design.
- Modeling relies heavily on abstraction.
- Design involves both product and engineering aspects.
- Product design is primarily focused on requirements.
- Engineering design is concentrated during implementation and design phases.
- Object-oriented analysis and design techniques are becoming standard.
Objectives
- Describe design and how different types handle product aspects.
- Present design as problem-solving, emphasizing abstraction and modeling.
- Place design within the software life cycle.
- Examine software engineering design approaches.
Topics
- Software products and design
- Abstraction and modeling
- Design varieties
- Software design in the life cycle
- Software engineering design methods
Importance of Software Design
- Design is crucial in creating functional and useful products.
- Design significantly impacts our daily lives economically and in terms of quality of life.
- Software has become increasingly important and pervasive.
- High-quality design has significant effects.
Software Products
- A software product is a collection of programs, data, and supporting resources meeting user needs.
- It can exist as a standalone artifact or be a vital component of another system.
Software Design Defined
- Software designers apply principles used in other design fields to software.
- Software design is meticulously specifying software to satisfy user needs while adhering to limitations.
Design as Problem Solving
- Problem-solving forms the foundation of design.
- Design often involves multiple solutions.
- Approaches such as problem redefining, experimentation, and brainstorming are helpful in design.
Design Principles
- Design principles act as guidelines for building well-structured, maintainable, and efficient software systems.
- The principles make software easier to comprehend, adaptable and reusable.
Abstraction
- Essential for problem-solving, especially in complex software design.
- It's about selectively highlighting specific aspects of a problem and neglecting the rest to simplify.
Importance of Abstraction
- Simplifies problems to facilitate solutions.
- Aids in focusing on the core components of a problem.
- Two common approaches are "top-down" and "bottom-up" strategies.
- Top-down strategy starts with a general solution and refines it.
- Bottom-up strategy begins with details and combines them to create a whole.
Modeling
- Models showcase the target in a structured fashion.
- Model components correspond to system parts, and interactions among parts are well-defined.
Modeling in Design
- Models simplify problem understanding.
- They assist in design creation and investigation.
- Documentation is enhanced and facilitated by modeling.
Static and Dynamic Models
- Static models depict software aspects that remain unchanged during runtime.
- Dynamic models portray the software's behavior during execution.
Design Methods and Components
- Design methods are systematic approaches to creating precise and complete software solutions.
- They comprise: a process, symbolic representations, principles, and rules (heuristics) to solve specific design problems.
Design Practices
- They offer established approaches and guidelines used to develop effective, maintainable, and scalable software systems.
- Include SOLID principles, design patterns, and processes for abstraction, decomposition, encapsulation, documentation, etc.
Design Practices (Continued)
- SOLID principles provide a structured approach to object-oriented software design.
- Design patterns offer tested solutions to common design challenges.
- Architectural patterns delineate high-level components for structuring complex systems (e.g., MVC, microservices).
Design Practices (Continued)
- Abstraction simplifies complex systems to focus on details.
- Decomposition breaks down intricate parts into smaller, well-defined components (eg., modules, classes, services).
- Encapsulation combines data with operations to protect data integrity.
- Documentation communicates design decisions through visual aids.
Why Design Practices Matter
- Follows a definite structure helping software adapt to modifications.
- Leads to high-quality products.
Design Principles Importance
- Provide guidelines for cleaner, reliable, and more manageable code.
- Reduced errors, flexibility, and better access for maintainers.
Design Method Timeline
- Historical overview of design methodology evolution.
Summary
- Software design is important, focusing on problem-solving.
- Abstraction and modeling are foundational techniques.
- Effective design incorporates both product and engineering considerations.
- Development phases (requirements, design, implementation, testing, and maintenance) are well-defined.
- Object-oriented approaches are standard in modern software engineering.
