Data is a broad term(facts and statistics collected together for reference or analysis.)
This can refer to inputs or outputs given to a person, a tool, a product, a system, interface.
In brief, it can refer to most things input and output in testing.
Did you have some specific purpose or scope in mind when asking about tools for the data?
I was thinking from a broader perspective, what should we be thinking about when it comes to data?
Who can we collaborate with from the rest of the company?
What types of tests should we be thinking of? (e.g pairwise testing was raising in our conversation) And as a consequence, what types of tools can assist us?
What tools could we make use of? What do data scientists use?
