Study Notes
Basic Software Architecture Concepts
- Software is composed of programs for tasks like messaging, browsing, or photo sharing; examples include WhatsApp, Google Chrome, and Instagram.
- Software can be proprietary (owned) or open-source (freely shared).
- Software engineers use programming languages like Python, Java, and C++ for development.
- Software instructs hardware on operations and functionality.
Software Components
- Software has two primary components:
- Client Side (Front End): Visible part that users interact with, including user interfaces like buttons and navigation.
- Server Side (Back End): Invisible to users; includes server, database, business logic, and data storage functionalities.
Quality Assurance Focus
- Back End Testing: Ensures server-side systems are secure, functional, and handle user load effectively.
- Front End Testing: Focuses on user experience, ensuring the application or website is visually appealing, functional, and user-friendly.
Modern Software Design
- Software has transitioned from monolithic architecture to microservices architecture, akin to a LEGO set where each piece handles a specific task.
- Microservices allow individual functionalities to be developed, tested, and maintained independently, enhancing efficiency.
Software Development Life Cycle (SDLC)
- SDLC outlines a structured process for developing high-quality software economically and efficiently.
- Key phases of SDLC include:
- Planning: Defines project objectives, scope, and deliverables; crucial for aligning with business goals.
- Design
- Development
- Testing
- Deployment
- Maintenance
SDLC Phases Breakdown
- Planning: Sets foundation; Quality Assurance (QA) involvement begins here with test case execution and bug verification.
- Deployment: Product is formally released, sometimes in stages; QA performs checks post-deployment.
- Maintenance: Focuses on software upgrades, bug fixes, and ensuring alignment with user requirements; involves monitoring and error management.
SDLC Approaches
- Companies choose different SDLC approaches to streamline the development process.
Waterfall vs Agile Methodologies
-
Waterfall:
- Sequential phases; challenges arise if clients change requirements after seeing the end product.
- Limited flexibility for unexpected changes.
-
Agile:
- Iterative and flexible; promotes constant collaboration and reassessment.
- Uses sprints (two to four weeks) for delivering working increments.
- Emphasizes working software over comprehensive documentation, which can lead to difficulties in budget and timeline predictions.
Scrum Methodology
- Involves short phases called "sprints" for project tasks.
- Features:
- Sprint planning to identify tasks.
- Regular reviews and retrospectives to improve processes.
- Continual cycle until the complete project scope is delivered.
Agile Release Planning
- Focuses on incremental releases instead of major launches.
- Plans are laid out for multiple sprints for smooth progression throughout the project lifecycle.
