If you lack experience in IT or are new to SQL, there is no need to worry. SQL is a user-friendly and intuitive language. Many individuals have acquired SQL skills independently, beginning with no prior knowledge. What is the highlight? No specialized software or costly textbooks are required to begin. All that is required is a web browser, an internet connection, and a readiness to acquire knowledge.

What is SQL?

SQL is a standardized programming language used as the foundation for managing and manipulating databases. A database is a software application created to store substantial data organizationally. It can store millions of records, a feat not achievable with a spreadsheet.

SQL enables you to execute a range of operations, including:

• Developing databases and constructing tables.
• Modifying tables and columns in a database.
• Modifying data by adding, updating, or deleting it.
• Obtaining data according to particular criteria.

This language empowers users to generate sophisticated and comprehensive reports. Using precise queries, you can extract specific information from a database to generate the required listings and comparisons. Currently, these reports frequently serve as the foundation for strategic decisions. For further information, explore our SQL Reporting track.

SQL is utilized by a diverse group of professionals, including data analysts, data scientists, software developers, and IT administrators. It is a versatile language crucial in today's data-centric world and applicable across various industries and professions.

SQL's history started in the 1970s. Read "The History of SQL – How It All Began."

SQL is not solely a historical artifact. It keeps developing and adjusting to the requirements of the contemporary world. This database language has evolved into an industry-standard acknowledged and utilized by all major organizations. It is the fundamental programming language for managing databases, utilized regularly by industry leaders like Google and Facebook for many operations.
