Photograph One A Day (30 Day April Project)
**The rules are simple:**
Take photographs **Each and Every Day** and post your best **ONE** (1) shot of the day - **EACH DAY** for **April**. If you happen to miss a day or two (life happens), it is **OK** to catch up and upload the photos for the days missed or just skip those days.
**Please don't post over 2 to 3 at a time**. This is part of the learning process.
**DO NOT POST TO THE ALBUM *UNTIL* AFTER 04/01/2026**.
Please use a browser like Chrome and the Meetup.com website to post the images, as **the Meetup app does not handle albums very well**.
Towards the top-left of the page is a link to **Add Photos** for uploading your photo to the album. **CONFIRM** **that your photo was Added to the correct Album.** Remember to post your **best photo (JUST ONE)** you took every day on that day! **DO NOT POST PHOTOS FROM ANY OTHER TIME!** If you have time to post an older image, you can take a new image and post it. Be creative.
Please **add a caption** to know how far you are in the process. After you upload the image you took that day, find your photo at the end of the album, and edit the caption to state the day and total of days in the month like this:**?/30**. You can add the title of the image if you wish. A good title can make a photo! So, your photo for the **April 1st** caption would be "**1/30: My great photo!**" \*\* Adding a caption helps you keep track of where you are in the month. It does help.
The purpose is to have fun and get in the habit of shooting every day. Learn to use your camera. Read your manual and test out a new feature you have never used before. Sometimes picking a theme/project can help focus (pun intended), like flowers, your pet(s), a lens you haven't used in a while, or whatever your passion is. Or try something new...
The **end date is 04/30/2026**. Meetup.com does not allow events to be longer than 2 weeks.
Other images that were not taken by you will be removed. Please keep the images family-friendly. You need to be a member of the Virginia Beltway Photography Group.
I look forward to seeing how far people go and grow as better photographers!

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.

Data & Analytics Wednesday - The Data-Driven Brand
**The Data-Driven Brand: Using Analytics to Shape Perception**
Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably âyesâ, but weâre not sure how to implement or test this theory.
For our April meetup weâve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy.
Sheâll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so weâre guessing thereâs more to that growth than really good guac (though the guac probably helps).
Ultimately, this talk focuses on the intersection of art and scienceâusing data to inform creativity and build a brand that resonates with customers in a measurable way.
**About Our Speaker**
Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasualâs Top 100 Movers & Shakers.

In-Person Event: The Answers to Depression & Anxiety
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 donât 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.
