SQL vs NoSQL
Structured Query Language is a domain-specific language whereas NoSQL is a type of database management system. Find out more key differences by watching this video.

What is SQL?
SQL stands for Structured Query Language, and it is a standard language used to manage and manipulate relational databases. SQL allows users to create, modify, and query databases, as well as to extract and manipulate data within them.
SQL is used to perform a wide range of tasks, such as creating and modifying database schema, inserting, updating and deleting data, and querying the database to retrieve information.

What is NoSQL?
NoSQL, short for "not only SQL," is a type of database management system that diverges from the traditional relational database model. It emphasises scalability, flexibility, and performance for handling large and unstructured data by utilising various data models, such as key-value, document, columnar, or graph databases.

What are SQL Subqueries?
Subqueries in SQL are queries that are nested within another query. They allow for more complex queries by enabling a query to reference the results of another query as a temporary table. This can be useful for filtering, sorting, and aggregating data in more complex ways than a single query can achieve.

What is Advanced SQL?
Advanced SQL refers to the use of more complex SQL features and techniques to perform advanced data manipulation and analysis. This can include subqueries, joins, aggregations, and window functions. Advanced SQL can be used to perform complex data transformations and generate insights from large and complex datasets.

About SQL interviews-
These are job interviews where the candidate is evaluated on their knowledge of SQL, including their ability to write and optimise SQL queries, create and manipulate databases, and understand database design principles. These interviews are common in data-related roles such as data analyst, data engineer, and database administrator.

What is a tech industry?
The tech industry refers to the businesses and organisations involved in the development, design, manufacturing, and distribution of technology products and services, including computer hardware, software, telecommunications equipment, and e-commerce services. It is a rapidly growing and constantly evolving sector with a significant impact on the global economy.
