Advanced Power BI Course: Master Data Modeling, DAX, and Report Design

Have you ever wonder why some Power BI dashboards are lightning-fast and easy to understand while others lag and confuse 🤔— the secret often lies in data modelling. Data modelling is the process of structuring your data in a way that makes analysis efficient, accurate, and meaningful. It’s the foundation that supports all your visualizations and insights. Here what a good data model does: 🔹 Connects tables logically using relationships (like one-to-many or many-to-many). 🔹 Eliminates duplicate data by organizing it into fact and dimension tables. 🔹 Improves performance by reducing data redundancy. 🔹 Enables powerful DAX calculations and accurate reporting. 💡#Tip: When it comes to arrangement always go for STAR schema as it’s simple, efficient, and makes your data model easy to manage. #PowerBI #DataModeling #BusinessIntelligence #Analytics #DataVisualization #MicrosoftPowerBI #DataAnalysis

🔹 Power BI for Data Analysis 001 — Introduction to Power BI Power BI is a critical tool in modern data analysis, helping professionals visualize, model, and make sense of their data efficiently. In this short video (<90 seconds), I provide a beginner-friendly explanation of what Power BI is, why it’s important, and how it fits into the data analysis workflow. This is the first episode in my Power BI for Data Analysis series — concise, actionable lessons to boost your analytical skills. #PowerBI #DataAnalysis #BusinessIntelligence #DataAnalytics #LearnPowerBI #OluwaseunInsight

DAX is the heart of Power BI – it helps you go beyond visuals and unlock real insights from your data. Here are some key categories of DAX functions that every Power BI learner should know: ◆ Calendar Functions ◆ Text Functions ◆ Aggregate Functions ◆ MIN / MAX ◆ Date Functions ◆ Filter Functions ◆ Related Functions ◆ Counting Functions ◆ ALL Function Whether you’re analyzing trends, building dashboards, or creating KPIs – understanding DAX gives you the power to transform data into meaningful stories. I recently learnt DAX in my Data Visualization class, and it was fascinating to see how powerful these functions are in transforming raw data into actionable insights. What’s your favorite DAX function and why? Let’s share and learn together.

💡 Mastering Cross Filter Directions in Power BI Data Modeling Post Content: When working in Power BI, understanding how cross filters work can make or break your data model’s accuracy and performance. A cross filter defines how filters flow between related tables — and getting this right is key to building efficient reports. 🔹 Single Direction: Filters flow one way (from dimension → fact). 🔹 Both Directions: Filters flow both ways (fact ↔ dimension). 👉 Use single direction for most models (like star schemas). 👉 Use both directions only when relationships need mutual filtering, like in many-to-many scenarios. ⚙️ Pro Tip: Overusing bi-directional filters can create ambiguity and slow performance. Always test your model after enabling them. #PowerBI #DataModeling #BusinessIntelligence #DataAnalytics #MicrosoftPowerBI #DAX #PowerBICommunity #DataEngineer #CrossFilter #Analytics

🎯 What is DAX in Power BI? 💡 DAX (Data Analysis Expressions) is a powerful formula language used in Power BI to perform calculations, create measures, and derive insights from your data! It helps you build dynamic reports and perform advanced analytics easily. 📊 Key Uses of DAX: ✅ Create calculated columns & measures ✅ Perform time intelligence (YTD, MTD, QTD) ✅ Build complex business logic ✅ Enhance data models with powerful expressions 🚀 With DAX, you can turn raw data into meaningful insights that drive better decisions! #PowerBI #DAX #DataAnalytics #BusinessIntelligence #PowerBIDashboard #DataVisualization #MicrosoftPowerBI #DataModeling #Analytics #DataDriven
