🚀 It's finally COMPLETE! I've officially finished my Sunrise Coffee Chain Performance Analysis (2023–2024). What caught my attention: transactions increased by 16.86%, while revenue and net profit both declined. The data had a story to tell. 🧵👇 github.com/Cephasia 👇👇

Scalar Subqueries in the SELECT Clause A scalar subquery is a subquery that returns exactly one value: one row and one column. You can use it inside the SELECT clause to calculate or retrieve a value for each row returned by the outer query. Unlike a regular subquery that might return multiple rows, a scalar subquery must produce a single value whenever it is evaluated.

☕ Where was the revenue coming from? 🤔 Espresso contributed 47.47%, while Food contributed 25.27%. Together, they accounted for 72.74% of revenue. Understanding product mix can reveal opportunities that total revenue figures alone might hide. #DataAnalytics

📊 More transactions didn't mean more money. Transactions grew by 16.86%, but revenue declined by 0.62% and net profit by 0.79%. This raised an important question: was the business attracting more transactions but generating less value per transaction? Analysis continues......

Insurance dashboard update Today I moved from the cleaning phase to building! Here's what I did: ✅ Wrote my DAX measures — Total Policyholders, Claim Penetration %, Total Claim Amount, Avg Claim & more ✅ Started building the Executive Summary page ✅ Began designing the dashboard layout in PowerPoint ✅ KPI cards and charts are taking shape Working with 37,542 rows of Insurance Policyholder data and the numbers are already telling a story. More pages coming this week #PowerBI #DataAnalytics #DAX #DashboardDesign

When next you’re for an event. Carry something worth commenting on. Maybe a unique type of tote bag or water bottle. Your next job can come from. “Oh I love your phone pouch”
