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.

Join us as we get together to see SIRAT, an Oscar-nominated Best International Film from Spain that follows a father, accompanied by his son, goes looking for his missing daughter in North Africa. Here’s a description, trailer and our plan for this event: DESCRIPTION: A father, accompanied by his son arrive at a rave deep in the mountains of southern Morocco while searching for his daughter who vanished months ago at one of these endless, sleepless parties. As their search continues, the journey forces them to confront their own limits. The film is directed by Oliver Laxe and stars Sergi Lopez, Bruno Nunez Arjona and Richard Bellamy. TRAILER: https://www.youtube.com/watch?v=ww-IXHXvS70 BUZZ & ACCLAIM: SIRAT has already won numerous awards, including 4 at the 2025 Cannes Film Festival, along with the Chicago, Montclair and Toronto International Film Festivals! It also earned a whopping 11 nominations at the 40th Goya Awards, including Best Film and Director, and was nominated for Best International Feature Film and Best Sound at this year’s Academy Awards. The film is earning a stellar 92% positive rating on Rotten Tomatoes which calls it “an unforgettable exercise in tension” and “a brutal reminder that the journey can be more important than the destination.” PLAN: Please purchase your ticket for the 7:00pm showing and we’ll meet inside the upstairs lobby between 6:40 and 6:50pm. Super Tuesday ticket price is just $6.50 (including online fee)! Advance ticket purchase is advised (via Gateway website preferred). Once you have yours, please list your seat number in the Comments section of this event! This one will be a “movie only” event. PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! Look forward to seeing you there, Dan

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

**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.
