Every Web Developer Must Know About Databases.| This artical useful for noobs

If you’re stepping into Web Development, understanding how data is stored, managed, and retrieved is a must! Let’s simplify the core concepts every web developer should master when it comes to database storage and management.

🔵 1. Relational vs Non-Relational Data (RDBMS vs NoSQL)

✅ Relational Data:

• Data is organized in rows and columns within tables.

• These use SQL (Structured Query Language) for managing data.

• Ideal when data is structured and relationships between entities are important.

🧠 Popular Relational Databases:

• MySQL

• PostgreSQL

• Oracle Database

• SQL Server

• IBM Db2

✅ Non-Relational Data (NoSQL):

• Non-tabular; stores data in formats like documents, key-value pairs, graphs, wide-columns.

• Great for scalability, flexibility, and handling large volumes of unstructured data.

🧠 Popular NoSQL Databases:

• MongoDB

• Apache Cassandra

• CouchDB

• Couchbase

🟢 2. Knowledge of Web Storage

Web developers should understand:

• LocalStorage & SessionStorage for browser-based storage

• Cookies for small pieces of data stored on the client side

• IndexedDB for storing large amounts of structured data on the browser

These are crucial when dealing with user sessions, preferences, and offline web apps.

☁️ 3. Cloud Databases – The Modern Standard

Cloud databases are hosted in cloud environments, providing high availability, automatic backups, and scaling.

📌 Famous Cloud Databases:

• Amazon RDS

• Azure SQL Database

• Oracle Autonomous Database

Cloud DBs are becoming the go-to solution for startups and enterprises alike.

🧱 4. Technology Stacks You Should Know

As a web developer, your database knowledge connects deeply with your tech stack. Here are the most popular:

🔰 MEAN Stack

• MongoDB (NoSQL DB)

• ExpressJS (Backend framework)

• Angular (Frontend)

• NodeJS (Runtime environment)

🔰 MERN Stack

• Similar to MEAN, but Angular is replaced with React JS

• Ideal for modern, fast-performing web apps

🔰 MEVN Stack

• Vue.js replaces Angular/React for the frontend

• Lightweight, beginner-friendly stack for building SPAs (Single Page Applications)

🔰 LAMP Stack

• Linux (OS), Apache (Server), MySQL (Database), PHP (Programming)

• A classic, battle-tested stack still used today!

💡 Final Words from AbdullahQureshiTalks

Whether you’re a beginner or already coding your way through web projects, having a strong grip on how databases work will level up your backend and full-stack development skills.

✨ Start with the stack that fits your learning style and project needs — and remember, databases aren’t just about storing data; they’re about designing smart systems.
