Which is field is better database or CUDA programming?
Which is better depends on what you’re more interested in. CUDA is a flavor of GPGPU (General-purpose computing on Graphics Processing Unit). Whether or not it ends up being practical is yet to be seen, but it’s definitely an interesting area of study. Database programming is a little more practical at the moment. It’s been around for decades and isn’t likely to disappear. But it’s also a lot less experimental because it’s more established. There are several different types, areas of study, and career possibilities. There’s also a greater real-world demand for database professionals.
