What are the advantages of using SQL over NoSQL?

Short answer: Structured Data: SQL is best suited for structured data where relationships between data are important.

Explain a bit more

ACID Compliance: SQL databases generally support ACID (Atomicity, Consistency, Isolation, Durability) properties, making them ideal for applications where data integrity is crucial, such as banking systems. Complex Queries: SQL databases provide powerful query capabilities with joins, subqueries, and aggregations. Maturity and Ecosystem: SQL databases have been around for decades, offering a robust set of features, tools, and community support.

Real-world example (ShopNest)

ShopNest’s SQL Server database stores customers, products, and orders. Good indexes and clear foreign keys keep checkout queries fast and safe.
