Offer Selection: Is it software development or data analysis?

Question: There are two offers recently. A is a software development job of a cash machine company, mainly for. net, and B is doing data analysis in a small company.
Background: Company A is a joint venture in Beijing. It is not big because the ATM system does not need to be updated frequently, so the work is relatively stable. Company B is also in the initial stage of data analysis, the project manager has 8 years of data analysis experience. Data Analysis is a hot topic and he is also interested in it.
Tangle: A's work is not very interesting, and it is generally said that it should be changed to management for soft start. I am not interested in management, and my salary is not high in Beijing,, but after one year of work, it will be relatively stable, with acquaintances.

I am more interested in data analysis of Company B, but I don't know how to develop because of this emerging profession. I am not very experienced in this company, and I don't know if I can learn the relevant knowledge and get training.
I am an automation graduate student, software engineer, girl. Please help me with the analysis. Thank you!
