Study Notes

System Development Methodologies

Waterfall Model: An iterative and incremental approach to software development, focusing on flexibility, collaboration, and customer feedback.
Agile Methodology: Emphasizes adaptive planning, evolutionary development, early delivery, and continuous improvement through close collaboration between cross-functional teams.
Iterative Model: Breaks down the software development process into smaller, manageable iterations, each involving a mini-Waterfall cycle of planning, analysis, design, implementation, testing, and deployment.
Spiral Model: Combines the iterative nature of prototyping with the systematic aspects of the Waterfall Model, involving repeated cycles of risk analysis, development, and testing.
V-Model: A sequential development process emphasizing testing throughout the software development lifecycle, with testing phases corresponding to development phases.
Prototype Model: An iterative approach that focuses on creating early, simplified versions of the final product (prototypes) to gather feedback and refine requirements.
DevOps: Emphasizes collaboration, communication, and integration between development and operations teams. DevOps streamlines the process, accelerates delivery, and improves software quality through automation.
Lean Software Development: Inspired by lean manufacturing, this methodology aims to maximize customer value by minimizing waste, effort, and resources.
Feature-Driven Development (FDD): An iterative and incremental software development methodology focusing on delivering features incrementally and emphasizing clear communication, domain modeling, and feature-based planning.
Rapid Application Development (RAD): Prioritizes speed and flexibility through iterative prototyping, frequent feedback, and rapid development cycles.

Understanding the System Development Life Cycle (SDLC)

Planning: Defining project scope, goals, timelines, resources, and key stakeholders. Assess project feasibility.
Analysis: Understanding the existing system and gathering user requirements. Define system needs and expectations.
Design: Creating a blueprint for the software system (architectural design, database design, user interface design, etc.).
Implementation: Writing the code for the software based on the design.
Testing: Evaluating the functionality of the software using various tests like unit, integration, and system tests.
Deployment: Launching the software in the live environment, training users, and transitioning data.
Maintenance: Ongoing support and maintenance to address issues, update the system, and enhance its functionality.

Requirements Gathering and Analysis

Interviews: In-depth conversations with stakeholders to understand their needs and perspectives.
Surveys: Structured questionnaires to gather data from a larger group of stakeholders.
Observation: Directly observing users in their environment to understand their workflow, challenges, and requirements.
Prototyping: Developing mock-ups or prototypes of the software to help stakeholders visualize and experience the proposed system.
Brainstorming: Collaborative sessions for idea generation and creativity.

Use Case Diagrams

Use Cases: Specific ways a system interacts with external entities (such as users or other systems) to achieve user goals.
Actors: The entities interacting with the system (e.g., customers, administrators, or other systems).
Relationships: Indicate how actors interact with the system.

System Design Principles

Client-Server Architecture: Distributes tasks between service requesters (clients) and providers (servers).
Layered Architecture: Divides a system into distinct layers (e.g., presentation, business logic, data) with each layer handling specific functionalities.
Microservices Architecture: Structures a system as a collection of independent, self-contained services.
Data Flow Diagrams (DFD): Illustrate the flow of data within a system.
Entity-Relationship Diagrams (ERD): Visual representations of entities and their relationships in a system.
Use Cases: Detailed descriptions of how a system interacts with users following predefined steps.

System Implementation

Installation: Setting up the hardware and software components.
Configuration: Configuring system settings, user accounts, and security.
Data Migration: Transferring data from existing systems to the new one.
Testing: Validating the system's functionality and performance, including unit, integration, system, and user acceptance testing.

System Deployment

Big Bang Deployment: Deploying the entire system at once.
Phased Deployment: Deploying the system in stages.
Pilot Deployment: Deploying the system to a limited group for feedback.

Maintenance Fundamentals

Corrective Maintenance: Fixing system defects.
Adaptive Maintenance: Modifying systems to fit changing needs.
Perfective Maintenance: Enhancing performance and functionality.

Software Testing

Unit Testing: Testing individual software modules.
Integration Testing: Testing interactions between modules.
System Testing: Testing the entire system.
Acceptance Testing: Validating the system against user needs.

Project Management

Project: Temporary endeavor to achieve a unique product, service, or result.
Project Life Cycle: Stages of a project from initiation to closure.
Project Management Knowledge Areas: Key areas of project management skillset.
Project Initiation: Initial phase of a project focusing on identifying objectives, stakeholders, and scope.
Project Planning and Execution: Defining the project's schedule, resources, strategies and actions.
Project Monitoring and Control: Tracking progress, managing risks, and ensuring deliverables meet quality standards.
Project Closure: Finalizing project activities, ensuring stakeholder satisfaction, and archiving project information.
