SQL for Data Analysis refers to the use of Structured Query Language (SQL) to explore, transform, and extract meaningful insights from data stored in relational databases. It involves writing queries to select, filter, aggregate, and join data from one or more tables, enabling analysts to answer business questions and support decision-making. SQL empowers users to clean, manipulate, and prepare datasets for further analysis or visualization, making it one of the most essential tools in data analytics and data science workflows. With SQL, analysts can work directly with large datasets, uncover patterns, and generate reports all using a consistent, powerful query language.
