If you're preparing for DBA interviews, the assignments and notes throughout the course get you ready to perform on the version most employers still run.

What learners say

★★★★★

I joined with zero database background and finished able to install, back up and recover a 19c database on my own. The architecture module at the start made everything after it click. Best decision for my career.

Rajesh KumarRKRajesh KumarLead DBA · Chennai
★★★★★

The RMAN and Data Guard sections are incredibly thorough. The instructor shows real failure scenarios and how to recover, not just the happy path. Being able to rewatch the recordings before interviews was a huge help.

Nadia HassanNHNadia HassanSenior DBA · Riyadh
★★★★★

Coming from app support, I wanted a complete 19c path. Building the two-node RAC cluster and practising patching and upgrades gave me the confidence to clear my interview and switch roles. Worth every rupee.

How do I get access after I pay?
As soon as your Razorpay payment is confirmed, your secure student-portal account is created automatically and the full course unlocks. You can start streaming within minutes — no waiting.
Is it lifetime access?
Yes. Buy once and your access never expires. Rewatch every lesson as many times as you need — including years later when you're prepping for an interview or hitting a new production scenario.
Can I watch on mobile?
Yes. Lessons stream in HD on mobile, desktop and tablet, so you can learn on your laptop at home and rewatch on your phone on the go.
Can I download the videos?
No — and that's by design. Lessons are streamed securely inside the portal rather than downloaded, which protects the content for every student. You still get to watch on any device, any number of times, for life.
What payment methods do you accept?
All payments are handled securely through Razorpay — UPI, credit and debit cards, and netbanking. Prices are in INR and are the final amount shown on this page.
Do I get a certificate?
Recorded courses don't include a completion certificate — they're self-paced, so there's no fair way to verify who has genuinely worked through every session. Our live training batches do include a course-completion certificate. What you get with every recorded course: lifetime streaming access, notes & scripts, assignments and WhatsApp support.
What is the refund policy?
Please review our full refund policy before purchasing. If you have any questions about eligibility, message us on WhatsApp and we'll help.
