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.

Why are we unhappy? Where does emotional pain come from? Studies show that people who suffer from long-term emotional pain have painful experiences in their lives that were never fully resolved in their mind. In other words, there were issues in the past that were not completely dealt with. This can include abuse in childhood, breakups, divorce, death of a loved one, to name a few. How do you know whether you have gotten over something painful? Here is an easy test: Do you still have attention on what had happened to you? For instance, do you still find yourself thinking about something painful that you went through? If you are, then you are not over it. In fact, in severe cases, people find themselves playing a "tape" in their mind over and over again. So how do you heal from your past? How do you stop the "tape" playing in your mind? In this meeting, you will learn a technique to help you with that. Come join us! 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 Dianetics and Scientology life improvement center.

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.*

**We will hike about 1.5 miles on a loop then reverse to get about 3 miles. The trail is flat but there are some roots etc. protruding so I’ll be using poles. There is an old homestead there that is interesting. I always feel as though this preserve reeks of peace and tranquility. We will hike at a pace of 3 to 3.5 mph (but you’re free to go faster if you’d like!)** **Optional lunch after if there is an interest.** **There is limited parking at the site so we will meet at Sam’s Bar (one mile south of Seymour) and carpool from there. Plan on departing from Sam’s at 10 am.**

Join us for a two mile trail hike alongside the Brookside Trail at Blendon Woods Metro Park. This trail is largely gravel and does include some hills and stairs. Hopefully we will see some wildlife while hike this scenic trail! Join us!

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

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 Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

**⚔️ Introduction to Wargaming & Painting Miniature Soldiers at The Arcane Foundry ⚔️** Join me in **The War Room at [The Arcane Foundry](https://share.google/S5i6DYJnJteHWeKtd)** for a laid-back evening of hobby talk and tabletop fun! For just **$25**, you’ll get a **3D-printed regiment of 20 high quality resin models** of your choice to paint — a **$40-$70 value if you were to buy them elsewhere!** (Please look up the price of minis, you are getting a steal). Bring your creativity, relax, and let’s make something awesome together. **Choose one from Below:** * 20 Cathayan Infantry * 20 Dwarf Warriors * 20 Wood Elf Spearmen Step into a world where strategy meets artistry — and where every painted figure tells a story of battle, honor, and imagination. Join **Daclaud** at **The Arcane Foundry** for an evening that introduces newcomers and enthusiasts alike to the timeless craft of **tabletop wargaming** and **miniature painting**. My own journey began with a fascination for fantasy — knights in armor, grim and hardened warriors, and monstrous creatures locked in epic battle. That passion led me to **Dungeons & Dragons**, where I painted my first **Basic Heroes set** and felt the spark that comes from bringing a character to life in miniature form. Not long after, I discovered **Warhammer Fantasy** and **Warhammer 40,000**, and I was hooked. The vision of vast armies clashing across the table — each unit meticulously painted, each story unfolding through dice and imagination — became my creative obsession. During this event, we’ll explore the **origins of wargaming**, from its early military simulations to the richly detailed worlds of modern tabletop battle systems. You’ll learn how to **build and customize your own armies**, paint your first figures, and experience the joy of turning strategy and storytelling into a hands-on art form. Whether you’re drawn by the lore, the hobby, or the thrill of commanding miniature legions, this introduction will open the gates to a world that has captivated hobbyists for generations. **🎨 RSVP today and join us at The Arcane Foundry — where every brushstroke and battle tells a story.**
