PostgreSQL Database

This hands-on course trains you to become a PostgreSQL Database Developer with strong SQL expertise.

You’ll master database concepts, advanced SQL queries, stored procedures, triggers, indexing, performance tuning, and real-world business use cases. Practical projects and industry-driven exercises ensure you’re job-ready from Day 1.

Tech Stack & Concepts Covered:
Database Basics & SQL

PostgreSQL RDBMS & SQL Fundamentals
Learn core database concepts, PostgreSQL architecture, and essential SQL operations:

DDL, DML, DQL, TCL commands for defining and manipulating data.

Filtering, sorting, built-in functions, and expressions for data analysis.

Advanced SQL

Complex Queries & Data Analysis
Master enterprise-level SQL techniques for data-driven applications:

Joins: INNER, LEFT, RIGHT, FULL OUTER, CROSS.

Subqueries: Nested & correlated subqueries for advanced filtering.

Set Operators: UNION, INTERSECT, EXCEPT for set-based operations.

Aggregate & Window Functions: SUM(), AVG(), RANK(), DENSE_RANK(), ROW_NUMBER().

CTEs (WITH clause) for cleaner, modular query writing.

Stored Procedures & Functions

Learn B-tree, Hash, and GIN indexes for optimized query performance and faster data retrieval.

Transactions & Concurrency Control

Manage data consistency using COMMIT, ROLLBACK, and SAVEPOINT.
Understand PostgreSQL’s MVCC (Multi-Version Concurrency Control), transaction isolation levels, and deadlock prevention.

Performance Tuning

Optimize queries with EXPLAIN and ANALYZE, indexing strategies, and query optimization techniques.
Work with execution plans to enhance performance for large datasets.

Security & User Management

Configure authentication, roles, and privileges using PostgreSQL’s role-based access control.
Manage security with GRANT/REVOKE and password encryption for secure database operations.
