In fact, this is another means of collecting money by NPC Economic Forum, which is not authoritative and has low social recognition. Just apply for an association registration from abroad, and then say that this is an imported product, the essence of which is to export to domestic sales. My classmates studying data analysis and data mining abroad have never heard of it and can't find it. Even if found, it is very little self-marketing content. After several years' observation, the examination contents and syllabus of CDA are changing, which also shows its instability, but the previous contents can't be found, only in the last year, perhaps in order not to let everyone see the clue.

Specifically, after the exam, it was discovered that the content of CDA training and the content combed before the exam had little to do with the content of the exam.

Of course, the knowledge I have learned is my own, but the authority of CDA and the course training of CDA are still questionable.

Its positioning is close to CFA and other high-end exams, but the manpower, material resources and quality spent by CFA in all aspects are worth the exam fee, but I feel that CDA is not good.
