In the past, data analysis techniques were rarely used in work. Through this training, many new tools, ideas, The method is very helpful for future work.
2. Participants in the Wireless Big Data Department: The courses are well arranged, with a lot of content, and the rhythm is also very well controlled. As a result, there is an open assessment and evaluation. After passing, the certificate is issued.
3. Students in the Network Technology Support Department: Learning is necessary. We used to rely too much on the help of manufacturers in the technology of data analysis, and customers need a long-term understanding of the business, which makes the communication cost of everyone relatively high. Now through the improvement of their own capabilities, on the one hand, they can solve some problems themselves, on the other hand, they will greatly reduce the cost of communication with manufacturers, which is very good.
Evaluation of business leaders
The CDA course system is relatively complete, and the certification has a certain amount of gold. This is the reason for our cooperation with CDA. This is the first cooperation. The development is very smooth. The overall feedback from everyone is relatively good. On the road of analysis, we will take a step forward.
