In the case of the real example of the students of the North Green Bird, some students have zero foundation, even how to install the software, what software to install do not know, under the guidance of the instructor, the students of the first step of the big data journey to be able to carry out.

Not to mention the content of big data learning there are many, Zhengzhou computer training/think Java is first of all the foundation, if you have the foundation is still slightly better, at least you can read and understand part of it, if you don't have the foundation, then it's very difficult to do.

Big Data Foundation stage to master the content of: Linux, MySQL foundation, Oracle foundation, Hadoop concepts, Python, spark and other knowledge points.

Specific knowledge points are difficult to understand self-study, and encounter problems no one can ask, which is a bitter thing.

So people who want to learn big data, especially jobs related to big data volume processing must have a basic foundation in computer science and statistics.

It has been said that a data scientist is a statistician who knows more about statistics than a programmer, and a programmer who is better at programming than a statistician, and that's very graphic.

But enrolling in a class to learn big data is much less difficult, first of all, psychologically there will be a great deal of relaxation, because learning in a class is similar to what we do in school, it is the main source of knowledge that we have gained since childhood.

Secondly, there are lecturers who have their hands on the book to explain the knowledge points, which is much more efficient than chewing on your own, with half the effort.

Lastly, in the class with students to study, learning atmosphere, their learning has a great role in promoting, and will not be able to communicate with each other, in a relaxed environment to obtain knowledge.
