What is the difference between SQL and NoSQL databases in Backend Application Development?

SQL and NoSQL databases are two different types of databases used in backend application development. SQL databases are structured and use a fixed schema to store data in tables with predefined columns and relationships. They are suitable for applications that require complex queries, transactional integrity, and structured data. On the other hand, NoSQL databases are unstructured and store data in a flexible, non-tabular format like JSON or XML. They are suitable for applications that need scalability, high-speed, and unstructured data. SQL databases use structured query language (SQL) for data manipulation, while NoSQL databases use various query languages, APIs, or even plain JavaScript. It is important to choose the right type of database based on the specific requirements and characteristics of the application.
