SQL Server Course for Beginners with 100+ examples - SQL Versus NoSQL

The video tutorial explains the differences between SQL and NoSQL databases. SQL follows a relational model with tables, rows, and columns, while NoSQL supports various formats like documents, key-value pairs, and graphs. SQL has been around since 1970, whereas NoSQL emerged in the late 2000s. Examples of SQL databases include MySQL and Microsoft SQL Server, while MongoDB is a popular NoSQL database. The video highlights the flexibility of NoSQL compared to the rigid structure of SQL and discusses ACID transactions, which are supported by SQL but not by all NoSQL databases.
