MySQL

1. Introduction to MySQL​

  • What is MySQL and why use it?
  • Installing MySQL (local setup or cloud-based solutions)
  • MySQL Workbench overview
  • Connecting to a MySQL server
  • Understanding MySQL client tools (e.g., CLI vs. GUI)

2. Basic Database Concepts​

  • What are databases, tables, rows, and columns?
  • Understanding data types in MySQL:
    • Numeric types (INT, FLOAT, DECIMAL, etc.)
    • String types (VARCHAR, TEXT, CHAR, etc.)
    • Date and time types (DATE, DATETIME, TIMESTAMP, etc.)

3. Relational Model​

  • Tables (relations)
  • Tuples (rows) and attributes (columns)
  • Domains(range) and data types
  • Constraints
    • Primary key constraint
    • Foreign key constraint
    • Unique, NOT NULL, CHECK constraints

3. Working with Tables​

  • Creating tables (CREATE TABLE)
  • Modifying tables (ALTER TABLE)
  • Dropping tables (DROP TABLE)
  • Adding and removing constraints (e.g., primary keys, foreign keys)

4. MySQL Queries​

  • Writing basic SQL statements
    • SELECT, INSERT, UPDATE, DELETE
  • Using WHERE clause for filtering
  • Sorting results with ORDER BY
  • Limiting results with LIMIT
  • Using aliases for readability

5. Advanced SQL Queries​

  • Aggregate functions (COUNT, SUM, AVG, MIN, MAX)
  • Grouping data with GROUP BY
  • Filtering groups with HAVING
  • Joining tables:
    • Inner joins
    • Left joins
    • Right joins
    • Full outer joins
  • Subqueries and nested queries
  • Using UNION and INTERSECT

6. Indexes and Performance​

  • What are indexes and how do they work?
  • Creating and using indexes
  • Understanding the impact of indexes on performance
  • Using EXPLAIN to analyze query performance

7. Stored Procedures and Functions​

  • Creating and using stored procedures
  • Writing custom functions
  • Using parameters in procedures and functions
  • Error handling in stored procedures

8. Triggers and Events​

  • Creating and using triggers
  • Use cases for triggers (e.g., logging changes)
  • Scheduling tasks with MySQL events

9. Transactions​

  • What are transactions?
  • Using START TRANSACTION, COMMIT, and ROLLBACK
  • Understanding ACID properties
  • Isolation levels and their impact

10. Database Security​

  • User management:
    • Creating users
    • Granting and revoking privileges
  • Securing connections (e.g., SSL/TLS)
  • Best practices for securing MySQL databases

11. Data Backup and Restoration​

  • Exporting data using mysqldump
  • Importing data into a database
  • Backing up and restoring databases
  • Automating backups

12. Working with Large Datasets​

  • Partitioning tables
  • Optimizing queries for performance
  • Using MySQL's full-text search capabilities

13. Advanced Features​

  • Views:
    • Creating and using views
    • Advantages and limitations
  • Temporary tables
  • Common table expressions (CTEs)
  • Using JSON data in MySQL

14. Integrations and Tools​

  • Connecting MySQL with programming languages (e.g., PHP, Python, Node.js)
  • Using MySQL with frameworks (e.g., Laravel, Django)
  • Exploring database management tools:
    • MySQL Workbench
    • phpMyAdmin

15. Cloud and Replication​

  • Setting up MySQL in cloud platforms (e.g., AWS RDS, Google Cloud SQL)
  • Understanding database replication
    • Master-slave replication
    • Multi-source replication
  • Load balancing and high availability

16. Best Practices​

  • Designing efficient schemas
  • Choosing appropriate data types
  • Writing efficient queries)
  • Avoiding common pitfalls (e.g., overusing indexes, poorly written joins)

17. Real-World Use Cases and Projects​

  • Building a relational database for an e-commerce site
  • Implementing user authentication and authorization systems
  • Storing and querying large datasets
  • Reporting and analytics using MySQL
