PostgreSQL for Data Science Bootcamp

Stack Overflow's Developer Survey has consistently ranked PostgreSQL among the most-admired databases — years of community trust from developers worldwide.

The backbone of some of the world's largest products and India's fastest-growing fintechs, e-commerce platforms, and SaaS companies.

Unlike Oracle or Microsoft SQL Server, PostgreSQL is 100% open-source — no license fees, no user limits, no vendor lock-in.

Handles structured tables and semi-structured JSON together, runs advanced analytics with window functions, supports geospatial data via PostGIS.

Fluency transfers directly to MySQL, Oracle, SQL Server, Snowflake, BigQuery and Redshift — roughly 90% of the syntax is shared.

Indian startups, unicorns, and MNCs are hiring PostgreSQL developers, DBAs, and data engineers at record rates.

No. The workshop is built for absolute beginners. Day 1 starts with what a database is, how to install PostgreSQL and PGAdmin, and walks through every step from scratch. If you can use a laptop, you can take this workshop.

Yes. Every live session is recorded and uploaded within 24 hours. You get lifetime access to all 9 recordings so you can revisit any topic anytime.

Yes. A signed completion certificate from PiyushAI Edtech Pvt Ltd is awarded after you finish the final Day 9 query-practice session. It can be added to your resume and LinkedIn profile.

Just a laptop with Windows, macOS, or Linux and a stable internet connection. We install PostgreSQL, PGAdmin, and Python together on Day 1 — nothing needs to be ready in advance.

Yes. GATE Data Science & AI includes Database Management and SQL as core topics. The Day 2 to Day 6 modules — CREATE, constraints, joins, subqueries, set operators, aggregate functions — directly map to the GATE DA syllabus and PSU IT Officer exams.

100% live on Zoom/Google Meet. You can ask doubts in real time during every session. Recordings are provided afterwards as backup, not as the primary mode.

The workshop fee is ₹499 for early-bird registration. A full refund is available up to 24 hours before Day 1. After the workshop begins, refunds are not provided since you retain lifetime access to recordings.
