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.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

**Confidence & Connection: Using Your Authentic Truth to Find Your People** Confidence isn’t just about believing in yourself, it’s about knowing where you belong and who you can grow alongside. In this April Confidence Lab Happy Hour, we’ll explore how living in your authentic truth helps you find your people, build meaningful collaborations, and create spaces where vulnerability is met with respect rather than risk. Together, we’ll reflect on what it looks like to advocate for yourself with clarity and care, and how confidence deepens when it’s rooted in connection rather than comparison. Featured speaker **Lachandra Baker**, founder of **[LBB Edutainment](https://www.lbbedutainment.com/)** and author of *Your Own Biggest Cheerleader*, will share reflections on authenticity, psychological safety, and the power of community over individual achievement. Drawing from personal stories—including the significance of turning 53—Lachandra will invite us into a conversation about showing up fully, being seen, and choosing relationships that support who you truly are. Expect a warm, welcoming atmosphere with space for reflection, shared insight, and intentional connection—plus drinks, light bites, and the kind of conversations that remind you you’re not meant to do this alone. Come as you are. Leave feeling clearer about your voice, your people, and the confidence that grows when both are aligned. **What is Confidence Lab?** Confidence Lab is a monthly community experience for bold, thoughtful leaders building confidence from the inside out. Whether you’re launching a business, leading a team, navigating change, or simply striving to show up more fully—you belong here. Our work demands clarity, courage, and conviction—but the pace of daily life can erode our sense of self. Confidence Lab creates space to reflect, reconnect, and grow with others doing purpose-driven work. It’s designed for entrepreneurs, nonprofit leaders, creatives, corporate professionals, activists, and anyone ready to lead with authenticity and impact. ***Please note:*** *All are welcome! If cost is a concern, please use promo code PUBLIC to access a free ticket—we want you to join us.*

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
