SQL or NoSQL: Which One Rules the Data World?

Data is at the heart of every modern application—but choosing how to store, manage, and scale it can make or break a system.

In this tech talk, we’ll dive into the ongoing debate between SQL (relational databases) and NoSQL (non-relational databases), with a special spotlight on MongoDB, the most widely adopted NoSQL database powering modern, data-heavy applications.

We’ll break down the strengths and trade-offs of both worlds:

• SQL Databases – structured, relational, and reliable for complex queries and transactions.
• MongoDB (NoSQL) – flexible, document-oriented, and built for scalability in applications that handle unstructured or rapidly changing data.

You’ll learn about:

• Key differences in data modeling, querying, and architecture
• When to choose SQL vs. MongoDB for your projects
• Real-world examples of how companies use MongoDB to scale applications like e-commerce, gaming, and social platforms
• Why many modern systems combine SQL and MongoDB to get the best of both worlds

By the end of this session, you’ll have a clear framework for deciding which database technology fits your application needs—and why MongoDB has become the go-to choice for developers building the next generation of apps.
