On the AI4DB side, I highlight query plan representation as a foundational abstraction for learning-driven optimization, pointing toward foundation models for databases. I will also discuss how large language models (LLMs) are beginning to rewrite queries and even construct indexes, challenging decades of handcrafted heuristics.<\/p>\n\n\n\n<p>In the second part, I turn to databases for AI and ask a more provocative question: Is RAG already reaching its limits? As AI systems evolve, we are moving beyond static retrieval toward agentic analytics, where AI agents interact with data systems in iterative, decision-driven loops. This shift raises a fundamental question: how should such systems be benchmarked?<\/p>\n\n\n\n<p>Overall, this talk presents a unified view of the evolving interplay between databases and AI.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Gao Cong&nbsp; Professor, College of Computing and Data Science (CCDS), Nanyang Technological University, Singapore Gao Cong is currently a Professor in the College of Computing and Data Science at Nanyang Technological University.
