Who wrote Database Management Systems?

Shreyash Tripathi, a Full-Stack Developer and UI/UX Engineer from India. He wrote the Job-Ready Series after struggling with scattered study material before his own placements, to give students one clear resource per subject.

Why I wrote these books

Before placements, my problem wasn't a lack of material. It was too much of it. A playlist for DBMS, a PDF for OS, three websites for DSA, and a new "must-watch" video every day. I kept switching sources, kept getting distracted, and never knew if I had covered what interviews actually ask.

I wrote them for students and early-career developers who want a serious internship or job and are tired of jumping between ten sources. Start with the free preview. If it helps, ask me for the full book.
