Join us for an engaging panel discussion on **AI Agentic Coding** and how autonomous AI systems are transforming the way software is built. Experts in AI, software engineering, and developer tools will share insights on how agentic AI—systems that can plan, reason, and execute coding tasks—is reshaping modern development workflows. The discussion will cover topics such as AI-assisted development, productivity gains, challenges around reliability and governance, and what the future of software engineering may look like with AI agents as collaborators. Whether you’re a developer, tech leader, or AI enthusiast, this session is a great opportunity to learn, ask questions, and explore how agentic AI is redefining coding

The inner circle consists of a small number of participants who actively discuss a topic, while those in the outer circle listen and observe. This format encourages participation from all members, as individuals from the outer circle can join the inner circle by taking an empty seat when they wish to contribute.](https://www.bing.com/ck/a?!&&p=00b4b265baa395dc4ad7b262d4d6e3b7b7c31b2195941076e51d2eca252c2d02JmltdHM9MTc2MjgxOTIwMA&ptn=3&ver=2&hsh=4&fclid=0e60c23d-2dbf-642d-0fd7-d4512c2b6597&psq=fishbowl+discussion&u=a1aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvRmlzaGJvd2xfKGNvbnZlcnNhdGlvbik&ntb=1)

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
