    1. Introduction to MySQL

    • Overview of MySQL: History, features, and popularity.
    • Use Cases: Where MySQL is commonly used (e.g., web applications, e-commerce platforms, content management systems).
    • Comparison with Other Database Systems: Understanding the differences between MySQL and other relational database management systems (RDBMS).

    2. Installing and Setting Up MySQL

    • Installation: Installing MySQL Server on various platforms (Windows, macOS, Linux).
    • Configuration: Configuring MySQL Server, setting up user accounts, passwords, and privileges.
    • MySQL Workbench: Introduction to MySQL Workbench for graphical administration and development.

    3. MySQL Basics

    • Connecting to MySQL: Using command-line tools (mysql client) and MySQL Workbench to connect to MySQL Server.
    • Creating Databases and Tables: Creating databases and tables using SQL statements (CREATE DATABASE, CREATE TABLE).
    • Inserting Data: Inserting records into tables (INSERT INTO statement).
    • Selecting Data: Retrieving data from tables (SELECT statement).
    • Updating and Deleting Data: Modifying and deleting records (UPDATE, DELETE statements).

    4. Data Types and Constraints

    • Data Types: Understanding different data types supported by MySQL (e.g., INTEGER, VARCHAR, DATE, TIMESTAMP).
    • Constraints: Adding constraints to tables (e.g., PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL).
    • Default Values: Setting default values for columns.
    • Auto-Increment Columns: Creating auto-increment columns for primary keys.

    5. Advanced SQL Queries

    • Joins: Understanding different types of joins (INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN).
    • Subqueries: Using subqueries to nest SELECT statements within other SQL statements.
    • Aggregation Functions: Using aggregate functions (e.g., COUNT, SUM, AVG, MAX, MIN) for calculations.
    • Grouping and Filtering: Grouping data using GROUP BY and filtering grouped data using HAVING.

    6. Indexes and Performance Optimization

    • Indexes: Introduction to indexes and their importance in database performance.
    • Creating Indexes: Creating indexes on columns for faster data retrieval.
    • Query Optimization: Techniques for optimizing SQL queries for better performance.
    • EXPLAIN Statement: Understanding query execution plans using the EXPLAIN statement.

    7. Transactions and Concurrency

    • Transactions: Understanding transactions and their properties (ACID).
    • Isolation Levels: Introduction to isolation levels and their impact on concurrent transactions.
    • Locking Mechanisms: Understanding locking mechanisms for ensuring data consistency in multi-user environments.

    8. Backup and Recovery

    • Backup Strategies: Different backup strategies for MySQL databases.
    • Database Dump: Using tools like mysqldump for database backups.
    • Point-In-Time Recovery: Recovering databases to a specific point in time.

    9. Security

    • Authentication and Authorization: Configuring user accounts, passwords, and privileges.
    • Encryption: Encrypting sensitive data at rest and in transit.
    • Auditing: Monitoring database access and activities for security compliance.

    10. Stored Procedures and Functions

    • Creating Stored Procedures: Writing and executing stored procedures.
    • Stored Procedure Parameters: Passing parameters to stored procedures.
    • Creating User-Defined Functions: Writing and using user-defined functions.

    11. Triggers and Events

    • Creating Triggers: Defining triggers for automatic execution of SQL statements in response to events.
    • Trigger Types: Understanding different types of triggers (BEFORE, AFTER, INSTEAD OF).
    • Creating Events: Scheduling recurring tasks using MySQL events.

    12. Full-Text Search

    • Full-Text Indexes: Creating full-text indexes for efficient text search.
    • MATCH AGAINST Syntax: Using the MATCH AGAINST syntax for full-text search queries.

    13. Replication and High Availability

    • Replication: Setting up replication for MySQL databases to achieve high availability.
    • Master-Slave Replication: Configuring master-slave replication for read scalability.
    • Master-Master Replication: Implementing master-master replication for high availability and load balancing.

    14. Scaling and Sharding

    • Scaling Strategies: Techniques for scaling MySQL databases vertically and horizontally.
    • Database Sharding: Implementing database sharding for distributing data across multiple servers.

    15. NoSQL Concepts and Comparison
