Yes, depending on the different functions used in created custom objects in the universe, you'll have objects. As I already gave you examples in my 2nd bullet in earlier post, some more examples are:
- Some databases use Case statement and others use Decode
- Some database used Concat() and others use something else
First things first: Why are you using different relational databases, can't you use one? What's the business requirement?
