What is Introduction to SQL and RDBMS about?
SQL is a standard language for accessing and manipulating databases. It allows users to execute queries to retrieve, insert, update, and delete data. SQL is a nonprocedural language, meaning the user specifies what they want rather than how to get it. Data in relational database management systems like Oracle is stored in tables which have columns and rows. Functions, joins, and subqueries allow users to perform calculations and combine data from multiple tables in powerful ways.
