Ionic.
Explanation:
Ionic compounds are formed when a cation reacts with an anion, where electrons are "donated". For covalent compounds, electrons are shared and only occurs between anions.
Where barium is the cation (metal)...
...and sulfate is a polyatomic ion that acts as an anion. It consists of one sulfate atom and 4 oxygen atoms.
Hope this helps :)
