What Is Software Development ?

Introduction

Software Development

Software development is the process of creating, developing, and testing programs to perform specific tasks on a computer or other device. Software developers write code for websites, desktop programs and apps. They create everything from video games to specialized software for telecommunications, and from rockets to medical devices.

Software Development Life Cycle (SDLC)

The SDLC is a framework that describes the activities performed at each stage of a software development project. Software is not something that is created randomly. There is a process to follow to make software functional, clean, secure, and easily maintainable:

 

1. Planning

2. Design

3. Development

4. Testing

5. Deployment

6. Maintenance

1. Planning

Planning is the first step in the Software Development Life Cycle (SDLC). It is important to clearly understand what is being built, why it’s being built, and who needs it. This helps prevent mistakes and wasted time.

·       Identify the need: Determine the purpose of the software and who will use it.

·       Gather Requirements: Collect detailed information about the software’s.

·       Feasibility Study: Assess the technical, economic, and operational feasibility.

·       Project Planning: Create project plan, including timelines, resource allocation, and risk management strategies.

2. Design

Design is the stage of shaping how the software will look both on the outside and inside which includes:

·       System Design: Define the overall architecture of the software.

·       Software Design: Create documents such as data flow diagrams, UML diagrams, and module designs.

·       User Interface Design: Design the user interface to ensure its user-friendly and intuitive.

 

3. Development

Development is the process of writing code to build working software — using programming languages such as:

·       Coding: Write the code using the chosen programming languages and tools.

·       Testing: Conduct unit testing to identify and fix bugs in individual code modules.

·       Integration: Combine the individual modules into a complete system.

 

4. Testing

Testing is the process of verifying that a software works as intended, is safe to use, and is reliable. It includes the following key aspects:

·       Unit Testing: Test individual components of the software.

·       Integration Testing: Test how different components interact with each other.

·       System Testing: Test the entire system to ensure it meets the specified requirements.

·       User Acceptance Testing (UAT): Involve end-users to test the software.

 

5. Deployment

Deployment is the stage where the software is prepared and delivered to users so they can begin using it. It involves the following key aspects:

·       Installation: Deploy the software on the target systems.

·       Configuration: Configure the software to specific settings and environments.

·       Data Migration: Migrate data from existing systems to the new software.

6. Maintenance

Maintenance is the assurance of the quality and longevity of software. It is not a one-time thing, it is a process that keeps software up to date, reliable, and serving users on an ongoing basis. It involves the following key aspects:

 

·       Corrective Maintenance: Fix bugs and errors.

·       Adaptive Maintenance: Modify the software to adapt to changes in the   environment or user needs.

·       Perfective Maintenance: Improve the software’s performance and usability.

·       Preventive Maintenance: Take proactive measures to prevent future problems.

 

Frontend vs Backend Development

Frontend Development: Frontend is the part of the software or website that users directly see and interact with. It is also known as client-side development.

 

Tasks of a Frontend Developer:

1. Design and build user interfaces (UI): Create the layout, structure, and visual elements users interact with.

2. Ensure responsive design: Make sure the website or app looks and works well on all devices (mobile, tablet, desktop).

3. Implement interactivity: Use JavaScript and frameworks to add dynamic behavior (e.g., form validation, dropdowns, and animations).

4. Debug and test frontend code: Identify and fix UI bugs and browser compatibility issues.

 

For example:

·       The buttons you click

·       The forms you fill out

·       The animations that appear on the page

·       The overall color scheme and layout of the website

 

Backend Development

Backend is the part of the software that operates behind the scenes. It manages the data, servers, and the overall system of the app or website. It’s also known as server-side development.

 

Tasks of a Backend Developer

1. Build and manage servers and APIs: Develop the logic and endpoints that connect the frontend to backend services.

2. Handle data and databases: Work with databases like MySQL, PostgreSQL, and MongoDB to store and retrieve data.

3. Ensure security and performance: Implement measures to keep data safe and ensure the application runs efficiently.

4. Write backend logic: Create the functionality behind features like user authentication, data processing, and transactions.

 

For example:

·       When you log in, the backend checks your username and password.

·       When you place an order, the backend saves your request.

·       When you search for information, the backend retrieves it from the database.

 

Programming Language

When you want to learn software development, the first thing that comes to mind is which language to start with. The answer is It depends on your goal.

 

What Do You Want to Do?

Your Goal                                                         Language

1. Website development                                     Html, CSS, JavaScript, Python 

2. Mobile App                                                    Dark (flutter), java

3. Game Development                                       C#, C++, Unity, Godot

4. Data Science                                                 Python

5. Backend/ Server side                                     Python, Node.js, PHP

6. General Purpose Coding                                 Python, Java, C++        

       

Essential Tools a Software Developer Needs      

1. Code Editor / IDE (Integrated Development Environment

How to Become a Skilled Developer: Understanding Git, Databases, APIs, and Testing

1. Git: Git is a program or tool used to store and manage changes made to the source code files of a software project. It helps you track change history, revert to previous versions, and collaborate with a team.

2. Database: It is a place or system for storing large amounts of data that is systematically organized to facilitate access, management, and storage of that data. It is used to store important information for companies, websites, and various programs.

3. API (Application Programming Interface): is a method or system that allows two software programs to communicate with each other, exchange data, and work together without directly exposing what is happening inside each one.

4. Testing: It is a test conducted to verify that a small part of the code (unit) works correctly. It prevents errors and ensures that new changes do not break the software.

 

Web Development

A responsive website is a website that works well on all kinds of devices such as mobile phones, tablets, and desktop computers.

Frontend Frameworks They are tools, libraries that help you build the visible part of a website or app quickly, and easily, which users interact with.

Backend Technologies They are the tools and languages used to build the server-side part of a website or app, where data is stored, processed, and managed.

Authentication is the process of verifying a user of a website or app—ensuring that the person logging in is authorized to access the service. For example, when you log into a website using a username and password.

Deployment is the process of making your website or app available online so that the public can access it on the internet.
