Hi DESG Community, It's been a while since we last met on Sep 2025. So much has changed and AI agents has been the talk of the time for past 6 months. For this month, we have Chin Hwee who will talk about: ***Your Data is Late Again! Handling Late-Arriving Data in the Modern AI Data Stack*** *"When we say we are processing the "latest" data in the data warehouse, which timestamp are we referring to?* *Late-arriving data can happen due to operational and technical reasons that may require data corrections, posing challenges in ensuring timely and accurate reporting of point-in-time data that drive AI systems and decision-making. In this talk, I will be exploring approaches on how we can design data systems and history-preserving data models that can handle late-arriving data in the modern AI data stack."* **Expected agenda:** **6.30pm - 7.15pm** \- Registration\, Pizzas & Networking **7.15pm - 7.20pm** \- Introduction **7.20pm - 8:00pm** \- Talk by Chin Hwee **8.00pm – 8.30pm** \- Q&A **8.30pm –** End of event Hope to you all soon!

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
