What is Orbix in distributed system?

Could you elaborate on the concept of Orbix in the context of distributed systems? I understand that Orbix is often mentioned in discussions about software middleware and communication frameworks, but I'm not entirely clear on its specific role and functionality within distributed systems. How does Orbix facilitate communication and collaboration between different components within a distributed system? And what sets it apart from other similar middleware solutions? I'm eager to gain a deeper understanding of Orbix and its importance in the world of distributed computing.
