🔍 What You'll Learn:

1. Database Basics and Practical Application: The lecture starts with a recap of basic database concepts. It then moves on to a practical application, where the lecturer introduces a sample database available on GitHub (titled 'films.sql'), which is used for SQL exercises. This database, structured with multiple tables, is designed to help students visualize and interact with real data.

2. Setting Up the Environment: The lecturer guides students on how to set up their environment for working with the sample database. This involves downloading the database file from GitHub, installing MySQL and MySQL Workbench on their computers, and ensuring that MySQL server is running locally (typically on port 3306).

3. Navigating MySQL Workbench: Once the environment is set up, the lecturer demonstrates how to use MySQL Workbench. This includes connecting to the local MySQL server, navigating the interface (which displays various schemas and tables), and understanding the basic layout and functionalities of the workbench, such as running queries and viewing tables.

4. SQL Queries and Operations: The focus shifts to executing SQL queries. The lecture covers various types of SQL commands for selecting, updating, and deleting data. It emphasizes the declarative nature of SQL, where users specify what they want done rather than how to do it. Examples include filtering data using the 'WHERE' clause, sorting with 'ORDER BY', and managing data pagination with 'LIMIT' and 'OFFSET'.

5. Advanced SQL Techniques: The lecture concludes with advanced SQL techniques. These include using aliases for column names, understanding different SQL operators, configuring case sensitivity in string comparisons, and implementing substring matching. The lecturer also explains the process of updating and deleting records, providing practical examples to illustrate these operations.
