What is OLE good for?

So, I'm curious to know, just what kind of benefits does OLE, or Object Linking and Embedding, offer in the world of technology and computing? I understand it's been around for quite some time, but I'm wondering if it's still relevant today and, if so, in what specific ways is it advantageous? Are there particular industries or applications where OLE shines as a valuable tool? I'm eager to learn more about its capabilities and how it can be Leveraged to enhance efficiency and productivity.
