Coding
✅ 1. What is Coding?
📌 Definition:
Coding (or Programming) is the process of writing instructions in a programming language that a computer can understand to perform specific tasks and functionalities.
💡 In simple terms: Coding is turning ideas, designs, and requirements into a working software application using a programming language like Python, Java, C#, JavaScript, etc.
🎯 2. Why is Coding Important?
Reason
Importance
Brings designs to life
Implements the system design into real software.
Solves business problems
Provides real solutions to user and business needs.
Creates automation
Reduces manual work and errors.
Enables interaction with users
Allows users to perform actions and get results.
Foundation for innovation
Builds the base for advanced features and tech.
✅ 3. Coding in the Software Development Life Cycle (SDLC)
Stage
Coding’s Role
After Design
Turns system architecture into working code.
Before Testing
Code must be completed and functional for testing.
During Deployment
The coded application is deployed to production.
✅ 4. Common Programming Languages
Language
Use Case
Python
Data science, AI/ML, web development, automation.
JavaScript
Frontend and backend web development (Node.js).
Java
Enterprise applications, Android apps.
C# (.NET)
Windows apps, web apps, game development.
PHP
Web development (WordPress, Laravel).
C/C++
System software, embedded systems.
SQL
Databases, data manipulation.
✅ 5. Key Concepts in Coding
Concept
Explanation
Variables
Store data (e.g., name, number).
Data Types
Type of data (e.g., string, integer, boolean).
Control Structures
Control flow (if-else, loops like for/while).
Functions/Methods
Reusable blocks of code.
Classes and Objects
Build components using Object-Oriented Programming (OOP).
APIs
Interface to connect different systems or services.
Error Handling
Managing runtime errors (try-catch blocks).
Comments
Notes in code for better understanding.
✅ 6. Example of Simple Code (Python)
pythonCopyEdit# Program to greet a user
# Function to greet
def greet(name):
return f"Hello, {name}! Welcome to our system."
# Taking user input
user_name = input("Enter your name: ")
# Calling function and printing result
print(greet(user_name))Explanation:
Define a function
greet.Take user input.
Call the function and print a personalized greeting.
✅ 7. Tools Used for Coding
Purpose
Examples
Code Editors/IDEs
Visual Studio Code (VSCode), PyCharm, IntelliJ IDEA, Eclipse.
Version Control
Git, GitHub, GitLab, Bitbucket.
Package Managers
npm (JavaScript), pip (Python), Maven (Java).
Compilers/Interpreters
Python interpreter, Java compiler (javac).
Debugging Tools
Built-in IDE debuggers, browser dev tools.
✅ 8. Best Practices for Coding
Best Practice
Reason
Write clean, readable code
Easier to understand and maintain.
Use meaningful names
Improves clarity (variables, functions).
Comment wisely
Explain complex logic without over-commenting.
Follow coding standards
Consistency in team projects (e.g., PEP8 for Python).
Modular coding
Reusable, organized code (functions, classes).
Handle errors gracefully
Prevent crashes and unexpected behavior.
Test code regularly
Catch bugs early (unit testing).
Use version control
Track changes, collaborate safely.
✅ 9. Role of a Business Analyst in Coding Stage
Activity
BA’s Role
Clarify requirements
Ensure developers understand the requirements.
Support developers
Answer business logic questions during coding.
Review development progress
Check if development aligns with requirements.
Participate in demos
Review partial builds, provide feedback.
Facilitate communication
Bridge between business and tech teams.
✅ 10. Summary of Coding
Aspect
Explanation
Definition
Writing instructions (code) to build software.
Languages
Python, JavaScript, Java, C#, SQL, etc.
Key Concepts
Variables, functions, classes, APIs, error handling.
Tools
VSCode, Git, compilers, debuggers.
Best Practices
Clean, modular, tested, well-documented code.
Role of BA
Ensure coding matches business needs.
