What is SQL?

When you dive into the realm of data, Structured Query Language (SQL) is the cornerstone that empowers you to interact with databases. Think of SQL as the essential language for communicating with a database, allowing you to execute tasks such as retrieving specific information, updating records, or creating and managing the structure of database systems.

SQL is a standard language recognized across various database systems, which means your skills in SQL can be applied to different types of databases like MySQL, PostgreSQL, SQL Server, and more. You’re not tied down to one piece of software, which significantly broadens your data management capabilities.

This powerful tool uses simple, declarative statements to perform different operations, and because of its straightforward syntax, SQL can often be easier to learn than other programming languages. Here’s a snapshot of what you can do with SQL:

• Query data from a database
• Insert records into a database
• Update existing data
• Delete records from a database
• Create new databases
• Create new tables in a database
• Create stored procedures in a database
• Set permissions on tables, procedures, and views

Unlike VBA, which is embedded within an office suite, SQL databases run on servers, meaning they can handle larger amounts of data, multiple users, and complex transactions more efficiently. They’re built to be highly reliable, available, and secure. Because databases are critical to business operations, knowing how to work with SQL is not just a skill—it’s a vital asset in today’s data-driven world.

Your ability to manage and manipulate massive datasets effectively can result in valuable insights, driving decisions that thrust companies forward. Working with SQL also entails understanding relational database management systems (RDBMS), which organize data into tables. This relational aspect is what allows for the powerful data analysis capabilities at your fingertips.
