SQL can be used to store, access and extract massive amounts of data to carry out the whole Data Science process smoothly. The beginning process involved in Data Science is to perform a lot of querying operations, a lot of search operation, extraction operation, editing or modifying operation to do all that while having Big Data we need a huge management system along with that we need language to perform all the operation that we want to do with data that’s why SQL comes in picture.
