Chai aur SQL — A Beginner's Journey into Databases
The article discusses the basics of SQL and databases for beginners. It explains the role of servers in hosting databases and the importance of understanding raw SQL despite the availability of ORMs like Prisma. Additionally, it covers the Data Definition Language (DDL) commands used to create and manage database structures.
- ▪SQL stands for Structured Query Language and is used to communicate with relational databases.
- ▪A database is software running on a server, which is a powerful computer that operates continuously in a data center.
- ▪Understanding raw SQL is crucial as ORMs can sometimes generate inefficient queries.
