"This course is an excellent choice for anyone who wants to learn data engineering using Python, Java, and SQL. By the time you complete this course, you will have a working understanding of Object Oriented Programming and how it is used to prepare, analyze and present insights from a variety of data sources: databases, text files, URLs (HTML, XML, JSON, Unicode) and more. Having a personal instructor to help you along the way is a valuable resource. My interaction with the instructors enhanced my understanding of the material. The instructor's feedback on my coding exercises and projects helped me to internalize what I was learning so I could solve coding problems on my own. Completing this course has greatly enhanced my competence as a data engineer who boosted my confidence level! Thank you for the excellent course materials and the feedback on my work by highly skilled instructors."- B.G., Rutgers, The State University of New Jersey

I am really glad to have finished this course with a solid understanding of my work.- David W.

I expected to get a thorough education in these areas, and that's exactly what I was provided. The Python courses were really good at starting from scratch and building up my knowledge step by step. The exams were very fair. The projects were excellent opportunities to practice what was taught, with the instructions being an excellent balance, between guiding me in the right direction while still giving me room to learn by doing. Any questions I had during the course were answered promptly, which I really appreciated! - Michael S.
