Hi, so basically BCA Data Science provided by Amrita Vishwa Vidyapeetham is quite advance and job oriented. Though the BCA course provided by Jain University is quite good too, with quite good range of subjects such as Artificial Intelligence, Cloud Computing, Cyber Security, Internet of things, etc.

The only difference in courses provided by these two universities is that Amrita University's Data Science program merely focuses on Data Science  although it have other advanced subjects as provided by Jain University too.

So if you are anywhere interested in Data Science you should definitely go for Amrita Vishwa Vidyapeetham, since they provide the curriculum for Data Science in an elaborative way. And if you want to learn data science for the sake of knowledge and not want to build your carrier around it then you should go for the Jain University.

Hope this is helpful.
