We live in a data-driven world, and SQL (Structured Query Language) is essential for managing data. SQL is used to manipulate and interact with data in a relational database. It's used by businesses of all sizes, from startups to large corporations, to extract insights from their data and make informed decisions.
But writing SQL code is not just about knowing the language — it's also about using best practices for coding and development. Poorly written SQL code can lead to performance issues, security vulnerabilities, and difficult-to-maintain databases. On the other hand, well-written code can make your database faster, more secure, and easier to manage.
