When I was let go at the last organization, I was very devastated and wanted to change my career path. Rather than being a developer, I wanted a database administration job, as it paid equally well yet had none of the hassle. So, when I started preparing for the Oracle Big Data 2017 Implementation Essentials part I exam, I took help from the study guides of this website. Now I am a certified professional database administrator and I lead a happy hassle free life. Thank you for everything.
