Hello.
Not strong enough (ironically)
data - yes, good
Goliath - at three syllables, it's a mouthful
I'd argue that Goliath.com is the only 'goliath' name one should own. (checks namebio.com).. And I'm right. Only three recorded sales with goliath and one was that domain.
You have such HUGE resources in the domain industry, of which namebio.com should be your #1.
If there is no precedent for a domain name selling in the same kind of mold (keywords etc), then there is no value and it's only hope and a whim kind of thing.
I like data names and own a good one. But see what's selling there, ensure what you are pursuing is backed by data itself!
