• What is PostgreSQL?: Overview of PostgreSQL, its features, and its advantages over other database systems.
• Installation and Setup: How to download, install, and configure PostgreSQL on different operating systems (Windows, macOS, Linux).
• PostgreSQL Tools: Introduction to PostgreSQL tools such as pgAdmin, psql (command-line interface), and other GUI tools.

2. Basic Database Concepts

• Relational Database Basics: Understanding the fundamentals of relational databases, including tables, rows, and columns.
• SQL Fundamentals: Introduction to SQL (Structured Query Language), including basic commands for data manipulation (SELECT, INSERT, UPDATE, DELETE).

3. Creating and Managing Databases

• Database Creation: How to create and manage databases and schemas in PostgreSQL.
• Table Creation: Creating tables, defining columns, and setting data types and constraints.
• Indexes and Constraints: Implementing indexes for performance optimization and constraints (e.g., PRIMARY KEY, FOREIGN KEY) for data integrity.

4. Querying Databases

• Basic Queries: Writing and executing basic SQL queries to retrieve data (e.g., SELECT, WHERE, ORDER BY).
• Joining Tables: Using JOIN operations to combine data from multiple tables (e.g., INNER JOIN, LEFT JOIN).
• Aggregating Data: Using aggregate functions (e.g., COUNT, SUM, AVG) and grouping data with GROUP BY.

5. Modifying Data

• Inserting Data: Adding new records to tables using INSERT statements.
• Updating Data: Modifying existing records with UPDATE statements.
• Deleting Data: Removing records with DELETE statements.

6. Advanced SQL Techniques

• Subqueries: Writing and using subqueries to perform complex data retrieval.
• Common Table Expressions (CTEs): Using CTEs for complex queries and improving query readability.
• Window Functions: Applying window functions to perform calculations across a set of rows related to the current row.

7. Data Integrity and Validation

• Data Types and Domains: Defining and using data types, and creating custom data domains.
• Triggers: Implementing triggers to automatically execute actions based on changes in the database.
• Stored Procedures and Functions: Creating and using stored procedures and user-defined functions to encapsulate logic and automate tasks.

8. Database Design and Normalization

• Design Principles: Understanding database design principles, including normalization and denormalization.
• Normalization Forms: Learning about different normalization forms (1NF, 2NF, 3NF) to design efficient and effective databases.
• Entity-Relationship Diagrams (ERDs): Creating and interpreting ER diagrams for database design.

9. Performance Optimization

• Query Optimization: Techniques for optimizing SQL queries to improve performance.
• Indexing Strategies: Using indexes to speed up query execution and understanding different types of indexes.
• Database Tuning: Configuring PostgreSQL settings and parameters for optimal performance.

10. Backup and Recovery

• Backup Methods: Using PostgreSQL’s tools and commands for creating database backups.
• Recovery Procedures: Restoring databases from backups and recovering data in case of failure.
• Point-in-Time Recovery: Implementing point-in-time recovery to restore the database to a specific moment.

11. Security and Access Control

• User Management: Creating and managing user roles and permissions in PostgreSQL.
• Data Security: Implementing security measures to protect data, including encryption and access control.
• Auditing and Monitoring: Tools and techniques for monitoring database activity and ensuring security.

12. Advanced Features

• JSON and XML Data: Working with JSON and XML data types and functions in PostgreSQL.
• Full-Text Search: Implementing and using full-text search capabilities for efficient text querying.
• Extensions and Customization: Using PostgreSQL extensions and custom functions to extend database capabilities.

13. Real-World Projects and Case Studies

• Hands-On Projects: Practical exercises to apply your knowledge, such as creating and managing a sample database for a real-world application.
• Case Studies: Analyzing examples of PostgreSQL in use in various industries and applications to understand best practices and solutions.

Who Should Take This Course?

• Database Administrators: Individuals responsible for managing and maintaining PostgreSQL databases.
• Developers: Programmers who need to interact with PostgreSQL databases as part of their application development.
• Data Analysts: Professionals who analyze and report on data stored in PostgreSQL databases.
• Students and Learners: Anyone interested in learning about relational databases and advanced SQL techniques.
