This is a great tutorial, really helps me a lot.
And I found some small mistakes (maybe) in the tutorial.

1. in paragraph 6.a Instal MySQL should be Install

2. in paragraph 7.a you said:
   "Set permissions for the directory: sudo rm -rf ~/data/db/"
   I thinks it should be chmod or sth

not finished yet but this tutorial has already helped me. Thanks for sharing your knowledge!

1. CategoryService#addNewCategoryInMysql use @RequestParam annotation, creates a new CategoryEntity using the params and then save it to db, while CategoryService#addNewCategoryInMongoDB use @requestbody annotation, call save on the param Category, is there any difference?

2. SellerService#addNewSellerInMongoDB and SellerService#addNewSellerInMysql also use @requestbody annotation, but they create and save a new Seller(or SellerEntity) instance, what's the difference compared to just call save on the param Seller(or SellerEntity)?

3. in SellerService#updateSellerInMongoDB, you retrieve the sellerInDatabase after it's updated successfully

if (updateResult.getModifiedCount() == 1)
        {
            sellerInDatabase = _sellerMongoRepository.findById(seller.getId()).orElseThrow(EntityNotFoundException::new);
            // ...
        }

I think it should be same as before it's updated(the first line in try block)?

Again, thanks for the great tutorial!
