Introduction
- Design: A problem-solving process to implement functional requirements while considering non-functional constraints (performance, security). Aims for high-quality design.
- High-Level Design (HLD): An abstract representation of the system. Shows how major software components interact. Used when developing a software product.
Architecture Design–Project
- Think-Pair-Share: Discuss architecture design from a software engineering perspective.
High-Level Design Considerations
- Reliability & Quality: Software continues to function properly even with input variations
- Software Security: Implementations and techniques to protect a software system from malicious attacks and hacker risks, ensuring it operates correctly. Should be considered at the system design level.
-
Software Vulnerability: The main cause of cyber security issues. Examples include:
- Buffer overflow attacks
- SQL Injection
- Cross-site Scripting
User Interface
- Definition: The visual part of a computer application or operating system, allowing user interaction.
- Examples: Keyboard, mouse, touch screen, voice recognition, Windows login screen (graphical interface examples: KDE Plasma, Aqua, GNOME Shell; display server examples: X11, Wayland, Quartz; window manager examples: awesome, Compiz, Open Box; kernel examples: Linux kernel, FreeBSD kernel, XNU kernel)
Architectural Design
- Definition: High-level model of a software system's functionality. Process of defining the collection of hardware and software components and interfaces to develop the framework of the software system.
-
Models:
- Monolithic
- Client/server
- Component-based
- Service-oriented
- Data-centric
- Distributed
Monolithic Architecture
- Description: All functions within a single program.
- Advantage: no need for cross-network communication
- Disadvantage: lack of flexibility and scalability.
- Examples: Current washing machines, home appliances
Client/Server Architecture
- Description: Server hosts and manages resources; client interacts.
- Advantage: Scalability & flexibility
- Disadvantage: Security vulnerabilities
Component-Based Architecture
- Definition: Software components interact with other components. Component encompasses certain functionality or their sets.
- Component-based Architecture Focus: Decomposition of the overall design into functional components; well-defined communication interfaces; providing better abstraction and sub-problem division.
- Example: ATM
Service-Oriented Architecture
- Description: Style of software design where services are available to other components.
- Advantage: Easy maintenance, reliability, availability, and scalability
- Disadvantage: Increased overhead (e.g., customer needs).
- Examples: Cloud computing and symmetric key management systems
Data-Centric Architecture
- Description: Data as the core asset; applications use and are built around this data.
- Advantage: Simplicity, security, and integrity management
- Disadvantage: Performance issues
- Example: Data Warehouse
Event-Driven Architecture
- Description: Software system behavior is driven by events, occurrences that trigger state transitions.
- Two types of events: Hardware vs. Software
- Advantage: Good performance
- Disadvantage: Complexity, potential race conditions
Distributed Architecture
- Description: Components on different platforms interacting via a network for a shared objective or goal.
- Advantage: Resource sharing, scalability
- Disadvantage: Complexity, security
- Examples: MongoDB, BlockChain
Think-Pair-Share Questions
- Question 2: Architecture design for a group project (read two text files and output formatted data to a new file) and identifying the best suitable architecture design.
Summary
- Software Security: Consider security in the system design phase.
- User Interface: Conceptual understanding.
- Architecture Design: Models (Monolithic, Client/Server, Component-based, Service-oriented, Data-centric, Distributed) discussed.
