What is SQL?
SQL, or Structured Query Language, is a standardized programming language used for managing and manipulating relational
databases. It is essential for various business applications, from simple data retrieval to complex transaction processing.

data management for businesses. It allows organizations to efficiently store, retrieve, and analyze large volumes of data, facilitating better decision-making. The ability to harness data effectively can lead to improved
customer insights, enhanced operational efficiency, and a competitive edge in the market.
How Does SQL Support Decision-Making?
SQL enables businesses to query their databases to extract relevant information quickly. This helps in generating
reports and
dashboards that provide valuable insights into various aspects of the business, such as sales performance, customer behavior, and inventory levels. By having access to real-time data, decision-makers can make informed choices that drive the company's
