Introduction to SQL: Understanding Structured Query Language | Q1 Oracle L12 P2 | SMILE ROAD

In this lesson, we introduce the fundamentals of Structured Query Language (SQL), the standard language used to communicate with relational database systems such as Oracle Database. SQL allows users to store, retrieve, manipulate, and manage data efficiently in modern information systems. The video explains the basic concepts of SQL, including how databases organize data into tables, rows, and columns, and how SQL commands are used to interact with that data. Learners will also explore the main categories of SQL commands such as Data Definition Language (DDL), Data Manipulation Language (DML), Data Query Language (DQL), and Data Control Language (DCL). To help reinforce understanding, the lesson includes Intended Learning Outcomes (ILOs), a comprehensive discussion, practice problems, multiple-choice questions (MCQs), and an answer key. This video is ideal for beginners studying database systems, information technology, computer science, and data analytics.
