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.

If you would like to subscribe to our email list outside of Meetup, we have changed platforms recently and you will need to register [here in Kit ](https://ohio-north-data-training.kit.com/b8f036f615)instead to receive emails. Agenda: **5:00 PM EST**: Online and in-person meeting begins with a social hour. This is an unstructured hour where you can join us to catch up and meet other group members before the session starts. There will be food brought in for in-person attendees. **6:00 PM EST**: Updates and announcements, followed by our feature presentation. See below for presentation details. **7:30 PM EST**: Optionally after the main presentations, the in-person crowd may go out for snacks and drinks at a local establishment. We hope to see you there! Session Abstract ### **Data Cleansing using Data Bricks** Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

Join us and work remotely together with like-minded UX folks. This is a last minute opportunity to get out at one of our favorites, [Junto](https://thejuntohotel.com/)! Plenty of seating is available in addition to a connected coffee shop and restaurant. I will be there 10-12 for sure, maybe longer. Feel free to come and go anytime during the day, and don't forget your charger and headphones!

**\*\*\*TO ATTEND THE EVENT, YOU MUST PURCHASE TICKETS THROUGH OUR WEBSITE\*\*\*** [https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup](https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup) Hosted by Pre-Dating Speed Dating, the experts, bringing people together since 2001! *Our events have been featured on CNN, CBS, Axios, Miami New Times, TLC's 90 Day Fiance - The Single Life, Tampa Bay Times, Southbend Times, Citylink Magazine, Essence, The Wall Street Journal, Best of Baltimore, AM New York, Chicago Tribune, WINK FM, Woman's World Magazine, and 100s more -- but come see for yourself!* Join us for a night of fun, flirtation, and possible romance at our singles speed dating event! If you're tired of swiping left and right on dating apps, speed dating is a great way to meet new people in person, in a relaxed, safe, and comfortable environment. **HOW IT WORKS:** We'll introduce you to at least 5, and up to 12 - or more - single women or men. Spend a little time with each one, during a series of 6-minute Pre-Dates. Then tell us who you'd like to speak with again & we'll do the rest! It's the modern, civilized, effective, and fun way to meet other professional-level singles. If you're finished with the games and ineffectiveness of online dating and apps, join us to share a wonderful evening of enjoyable conversation with interesting people... and maybe something magical will happen! **GET TICKETS:** A Meetup RSVP is not a ticket, you must purchase on our website. [https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup](https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup) Use Code MATCH5 for $5 off! **DOES IT WORK?** Yes! According to the New York Times, at a speed dating event, people like 2-3 out of 10 people they meet. Online daters only match with 1 in 100 or fewer of the profiles they study. This is the best way to meet new people, and it works! Just ask the thousands of people that have met at our events and had successful relationships and marriages. **WHAT DOES IT COST?** We put a lot of time and effort into creating the best singles events possible, so we collect a fee for our hard work. Our events are an excellent value at about $3 per introduction. Get your ticket for the best singles event in town. **NOTE FOR NEWCOMERS:** We post our events on various platforms. Our events often sell out, so expect plenty of fellow singles, regardless of the numbers you see here :) So what are you waiting for? Join us for some fun conversation with great new people... and maybe something more! Who will you meet? **GET TICKETS:** [https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup](https://www.pre-dating.com/columbus-speed-dating/?utm_source=meetup&utm_medium=event_listing&utm_campaign=meetup) #singles #singlesevents #speeddating #love #relationships
