Semantic layers are not new, they started in 1991, when BusinessObjects patented the semantic layer. It’s a great concept but it hasn’t really taken hold in the enterprise. Now LLMs are generating renewed interest in the semantic layer. Semantic layers really unlock the future of where things will go with AI. If you want trustworthy data, you need a semantic layer. If you let an LLM loose on a schema versus let an LLM loose on a semantic layer on top of that schema with some basic curation, you're going to get much better results.
Love this and also, Data Product is trending :) No GenAI without Clean Data Products
