What Is SQL?

SQL stands for Structured Query Language. It is a programming language that is used to communicate with relational databases. For instance, an analyst may use SQL to find the total sales of a company, identify its most popular products, or compare customer activity across different months. Learners do not need to become an advanced programmer to start learning SQL. Beginners can start with simple queries and gradually learn more advanced concepts.

• Retrieve data from databases
• Filter specific records
• Sort and organise information
• Combine data from different tables
• Calculate totals and averages
• Identify trends and patterns
• Create reports from database information
• Clean and prepare data for analysis

In addition to this, learning SQL can also complement other data analytics skills. For instance, analysts often combine SQL with Excel, Python, Power BI, Tableau, and statistics.
