Is Chainlink part of Solana?

Excuse me, could you clarify something for me? I've been reading about various blockchain projects and I'm a bit confused about the relationship between Chainlink and Solana. I've heard Chainlink mentioned in several contexts as a leading oracle solution, and I know Solana is a high-performance blockchain platform. But I'm not sure if Chainlink is actually part of Solana or if they just work together in some way. Could you please elaborate on this point? It would really help me understand the ecosystem better.
