# Mastering RDBMS (Relational Database Management System)

## Overview

In the field of database management, Database Management Systems (DBMS) are crucial for efficiently managing and manipulating data. DBMSs can be broadly classified into two types:

1. **Relational DBMS (RDBMS)**

2. **Non-Relational DBMS**

A **Relational Database Management System (RDBMS)** is a type of DBMS that structures data into tables, with relationships defined between these tables to ensure data integrity and support complex queries.

### Examples of RDBMS:

- **MySQL**

- **Microsoft SQL Server**

- **PostgreSQL**

- **Oracle**

- **IBM DB2**

## Repository Contents

This repository is designed to provide a comprehensive course on **MySQL** and **Microsoft SQL Server**, two widely used RDBMS platforms. The course covers fundamental and advanced topics, with each lecture focusing on a specific aspect of RDBMS.

### Course Outline

Below is the list of lectures included in this course. Each lecture is accompanied by:

- **Two SQL Files**: One for MySQL and one for SQL Server.

- **Lecture Guide**: A detailed README file explaining the topic and SQL scripts.

#### Lectures:

1. **Lecture01-DatabaseAndTableCreationAndDataInsertion**  

   - Overview of databases and tables  

   - Creating databases and tables  

   - Inserting data into tables  

2. **Lecture02-DatabaseOperationsAndDataManipulation**  

   - CRUD operations (Create, Read, Update, Delete)  

   - Using `SELECT` with conditions (`WHERE`)  

   - Data modification commands (`INSERT`, `UPDATE`, `DELETE`)  

3. **Lecture03-AggregateFunctionsAndTableAlteration**  

   - Using aggregate functions (`SUM`, `AVG`, `COUNT`, etc.)  

   - Altering tables (adding/removing columns)  

   - Basic data analysis with SQL  

4. **Lecture04-DatabaseRelationshipsAndKeys**  

   - Understanding primary keys, foreign keys, and unique constraints  

   - Creating and managing relationships (One-to-One, One-to-Many, Many-to-Many)  

   - Introduction to joins  

5. **Lecture05-SQLJoinsAndViews**  

   - Types of joins (Inner, Left, Right, Full, Cross)  

   - Creating and managing database views  

   - Querying data through views  

6. **Lecture06-SubqueriesAndNestedQueries**  

   - Introduction to subqueries  

   - Writing nested queries  

   - Performance considerations for complex queries  

7. **Lecture07-StoredProceduresAndFunctions**  

   - Writing stored procedures for reusable logic  

   - Creating user-defined functions  

   - Parameterized queries and error handling  

8. **Lecture08-TriggersAndTransactions**  

   - Creating and using triggers for automated tasks  

   - Understanding transactions (`COMMIT`, `ROLLBACK`, Savepoints)  

   - Ensuring data consistency with transactions  

9. **Lecture09-IndexesAndPerformanceOptimization**  

   - Types of indexes (Clustered, Non-Clustered)

10. **Lecture10-DataSecurityAndUserManagement**  

    - Managing roles and permissions  

    - Securing sensitive data with encryption  

    - User creation and management  

11. **Lecture11-AdvancedQueryTechniques**

    - Restoring databases  

    - Disaster recovery planning  

13. **Lecture13-NoSQLIntegrationAndHybridSystems**  

    - Overview of NoSQL databases  

    - Integrating RDBMS with NoSQL for hybrid systems  

    - Practical examples of RDBMS and NoSQL usage  

### Comments and Syntax

To enhance understanding, extensive comments are included within the SQL files. Both SQL Server and MySQL use the `--` syntax for comments to explain the code and concepts in detail.
