Instructor: N/A • Language: N/A

Master PostgreSQL for developers including database design, advanced SQL queries, performance tuning, and scaling.

Description

PostgreSQL is the world's most advanced open source relational database, used by companies worldwide for applications that require robustness, scalability, and performance. This course is designed specifically for developers, skipping theory overload and focusing on real world, practical skills you can apply immediately. You will learn fundamentals of relational databases, installation and configuration, basic SQL commands (SELECT, INSERT, UPDATE, DELETE), advanced SQL queries (joins, subqueries, set operations), aggregate functions, grouping data, database schema design, primary and foreign keys, transactions, triggers, and PostgreSQL extensions.

This Course Offers

  • Complete PostgreSQL fundamentals for developers: Learn fundamentals of relational databases, relational model concepts (tables, columns, rows, keys), installation and configuration, creating databases and users, data types and operators.
  • Basic and advanced SQL queries: Master basic SQL commands (SELECT, INSERT, UPDATE, DELETE). Write advanced SQL queries including joins, subqueries, set operations, aggregate functions (SUM, AVG, COUNT, MIN, MAX), and grouping data with GROUP BY.
  • Database schema design and relationships: Design clean and normalized database schemas from scratch. Create tables and define relationships using primary keys, foreign keys, and unique constraints.
  • Transactions, triggers, and extensions: Understand transactions and data integrity, triggers and rules, and PostgreSQL extensions and modules for extending database functionality.

Why We Love This Course

  1. It is designed specifically for developers transitioning from MySQL, SQLite, or other RDBMS to PostgreSQL.
  2. One student review noted the course is very informative and quality education. Another said it is good but needs more practical questions.
  3. It covers performance optimization using indexing, query planning, and caching techniques.
  4. It is beginner friendly with no prior SQL or PostgreSQL experience required.

PostgreSQL is the database of choice for modern applications. The question is whether you want to master PostgreSQL for designing, querying, and scaling databases as a developer, or stick with simpler databases that lack advanced features.

Course Eligibility

  • Developers switching from MySQL, SQLite, or other RDBMS to PostgreSQL.
  • Software engineers looking to strengthen their database skills.
  • Web developers, backend engineers, and full stack developers.
  • Anyone building data driven applications or APIs.

Course Requirements

  • No prior SQL or PostgreSQL experience is required.
