CS403 Midterm prep(lecture 16 to 18) | detailed concept | highlighted handout | Mcqs & short

Welcome to this essential video covering **CS403 Lectures 16 through 18**! In this session, we shift from database design theory to practical implementation by introducing **SQL (Structured Query Language)**. This is a critical topic for your midterm exam and for anyone wanting to work with real-world databases. We start with the basics of SQL, explain its different sub-languages (DDL, DML, DCL), and then guide you through writing your first SQL statements to create tables and manipulate data. *🔥 TOPICS COVERED (Lec 16-18):* *Lecture 16: Introduction to SQL* What is SQL and why is it the standard language for relational databases? *Categories of SQL Commands:* *DDL (Data Definition Language):* Commands to define database structure (e.g., `CREATE`, `ALTER`, `DROP`). *DML (Data Manipulation Language):* Commands to manage data (e.g., `SELECT`, `INSERT`, `UPDATE`, `DELETE`). *DCL (Data Control Language):* Commands for security and access rights (e.g., `GRANT`, `REVOKE`). Key benefits of using SQL (non-procedural, unified, standard). *Lecture 17: SQL Data Types & Creating Tables* Common SQL Data Types: `CHAR`, `VARCHAR`, `NUMBER`/`INT`, `DATE`, etc. *The `CREATE TABLE` Command:* Syntax and examples for creating new tables with specific columns and data types. Introducing basic constraints like `PRIMARY KEY` and `NOT NULL`. *Lecture 18: Basic Data Manipulation (DML)* *The `INSERT` Command:* Adding new rows of data into a table. *The basic `SELECT` Command:* Retrieving data from a table. Selecting all columns (`SELECT *`). Selecting specific columns. Using the `WHERE` clause to filter rows based on conditions. *The `UPDATE` Command:* Modifying existing data in a table. *The `DELETE` Command:* Removing rows from a table. *⏰ TIMESTAMPS:* (Please adjust these based on your video) 0:00 - Introduction & Importance of SQL 1:30 - Lec 16: What is SQL?
