SQL (Structured Query Language) is one of the essential languages used for managing and querying data in relational databases. It is the backbone of database management systems, allowing users to retrieve, update, and manipulate data efficiently. This course, "SQL Structured Query Language", offered by the British Academy for Training and Development, aims to equip participants with the necessary skills and knowledge to work with relational databases using SQL. Over 10 days, the course will cover basic to advanced SQL concepts, from writing simple queries to dealing with complex databases. This course is ideal for developers, data analysts, database administrators, and anyone interested in enhancing their database management and data analysis skills with SQL.
