@_missoma Star schema is tough at first but once it clicks, your data models become so much cleaner. Stick with it — the headache is worth the payoff! 💪

Dear data analysts, how often do you use star schema when working with data in Power BI?
Stumbled on it during my Power BI course and so far nothing has given me more headache than star schema 😩

Two main questions to ask yourself before building a dashboard as a Data Analyst: 👇🏻
1. What problem are you trying to solve?
2. Who are you designing this for?
You may think that you have the newest and greatest dashboard built, but if it doesn't solve the immediate concerns or problems of your end consumer or stakeholder, they're not going to be using the dashboard.

Your CEO sends you a Slack message:
Emergency. Customer retention fell last month. We need a plan before the board meeting.
You check your dashboard:
•Retention: 68% (down from 72%)
•Churn: 32%
•Customer base: 15,000
•Avg customer lifetime: 9.2 months (down from 10.1)
•MRR: $1.8M (up 3%)
Your challenge:
Before responding, you have 2 hours to understand the situation.
What are the first three things you’d investigate to determine:
1.Whether retention actually declined or if the metric is misleading
2.If this is a real crisis
3.What insight leadership actually needs
Bonus:
What would your Slack response to the CEO say?

Just started my PowerBI journey and honestly? The learning curve is real, but so is the payoff.
Going from raw data to actual visual stories you can understand at a glance is something else. Slowly figuring out how to navigate the interface and build dashboards.
Data visualization is actually kinda fun once you crack the hard part 😅

@TechnicalBben That "how to be serious" must be what I'm going through right now.
What do I say?
How do I position myself?
What do I learn?
Which app should I focus on?
English

When I was starting in tech, I was confused and scared. I wanted opportunities, but I did not know what “being serious” was supposed to look like.
I took free courses and completed them. I was learning.
But the moment it came to the real stuff, the uncomfortable stuff, like watching long videos on how to actually land jobs on Upwork or position yourself on LinkedIn, I could not finish them. One minute in, I was out.
Not because I was incapable. Because I was avoiding the discomfort.
I was on Upwork for a long time without knowing what I was doing. I would start tutorials on how to win jobs, close them halfway, and still tell myself I was trying.
But here is the interesting part.
I still tweaked my profile. I updated my bio. Added my certifications. Looked at other profiles and adjusted mine to look more structured. I started applying to jobs, even if I was not fully confident.
That was my borrowed seriousness I would blow I have watch the videos lmao 🤣 but I didn't.
I was not verified. I did not have a mentor. I did not have a perfect strategy. I was not fully disciplined. But I looked like someone who was trying.
Then one day, someone sent me a direct message.
I genuinely thought it was fake. It was not.
I got the job. I was earning 5 dollars a day. It was small, but at that time I was broke. That money mattered. More importantly, it proved something to me.
Opportunities were real.
They were not only for people who felt ready. They were not only for people who finished every tutorial or understood everything perfectly.
They were for people who showed up, even imperfectly.
That one small win gave me clarity. From there, I kept trying. Failing. Adjusting. Trying again. No mentor. Just consistency and courage in small doses.
A year after finishing university, I made my first million.
I was never fully ready. I was not perfectly serious at the beginning.
But even borrowed seriousness moved my life forward.
You do not need to feel 100 percent prepared. You do not need to master everything before you start.
Sometimes, acting like you belong is enough to get your first shot. And that first shot can change everything.
Technical Ben@TechnicalBben
Even if you fake seriousness, doors will still open. The world rewards posture before performance. Act like you belong and watch what happens.

Learning data analysis and working on a project has made me realize something. Data analysts, strategists, consultants, or whatever the proper umbrella term is....are not talked about enough.
I mean, having the brain power to put in clear, practical terms, complex business problems and offer proper solutions just by looking at a screen filled with numbers, patterns, and scattered data. That's some genius level sh*t!
