Business Intelligence & Reporting Business Intelligence (BI) and reporting involve transforming raw data into actionable insights using visualization tools like Power BI, Tableau, and Google Data Studio. 1️⃣ Power BI & Tableau Basics These tools help create interactive dashboards, reports, and visualizations. Power BI: Uses DAX (Data Analysis Expressions) for calculations and Power Query for data transformation. Tableau: Uses calculated fields and built-in functions for dynamic reporting. 2️⃣ Essential Features in Power BI & Tableau 🔹 Dashboards: Interactive visualizations combining multiple reports. 🔹 Filters & Slicers: Allow users to focus on specific data. 🔹 Drill-through & Drill-down: Navigate from high-level to detailed data. 🔹 Calculated Fields: Custom metrics for analysis. 🔹 Data Blending: Combine multiple sources into a single report. 3️⃣ Power BI Key Concepts ✔ DAX (Data Analysis Expressions): Used for creating custom calculations. Example: Calculate Total Sales Total_Sales = SUM(Sales[Revenue]) Create a Year-over-Year Growth Rate YoY Growth = ( [Current Year Sales] - [Previous Year Sales] ) / [Previous Year Sales] ✔ Power Query: Used for data cleaning and transformation. Remove duplicates Merge datasets Pivot/Unpivot data ✔ Power BI Visuals Bar, Line, Pie Charts KPI Indicators Maps (for geographic analysis) 4️⃣ Tableau Key Concepts ✔ Calculated Fields: Used to create new metrics. Example: Total Profit Calculation SUM([Sales]) - SUM([Cost]) Sales Growth Percentage (SUM([Sales]) - LOOKUP(SUM([Sales]), -1)) / LOOKUP(SUM([Sales]), -1) ✔ Tableau Filters Dimension Filter (Category, Region) Measure Filter (Sales > $10,000) Top N Filter (Top 10 Products by Sales) ✔ Dashboards in Tableau Drag & drop visualizations Add filters and parameters Customize tooltips 5️⃣ Google Data Studio (Looker Studio) A free tool for creating interactive reports. ✔ Connects to Google Sheets, BigQuery, and SQL databases. ✔ Drag-and-drop report builder. ✔ Custom calculations using formulas like in Excel. Example: Create a Revenue per Customer metric: SUM(Revenue) / COUNT(DISTINCT Customer_ID) 6️⃣ Best Practices for BI Reporting ✅ Keep Dashboards Simple → Only show key KPIs. ✅ Use Consistent Colors & Formatting → Makes insights clear. ✅ Optimize Performance → Avoid too many calculations on large datasets. ✅ Enable Interactivity → Filters, drill-downs, and slicers improve user experience. Mini Task for You: In Power BI, create a DAX formula to calculate the Cumulative Sales over time.

Business Analyst Interview Questions and Answers 👇👇 1. What is analysis in tableau? Ans: Tableau comes with inbuilt features to analyze the data plotted on a chart. We have various tools such as adding an average line to the chart which tableau calculates itself after we drop the tool on the chart. Some other features include clustering, percentages, forming bands of a particular range and various other tools to explore and inspect data. All these tools are available in analyze tab on each sheet used to create any chart. The features become visible only when they are applicable to the worksheet. 2.How to create sets in tableau? Ans: Sets are custom fields used to compare and ask questions about a subset of data. For creating a set on dimension, right-click on a dimension in data pane and select create -> set. In general tab select the fields that will be considered for computing the set. Specify the conditions to create set in conditions tab and you also have the option to select top N members in dataset based on any field in the top tab. When a set is created it divides the measure into two parts namely in and out of the set based on the conditions applied by the user. 3.Why and how would you use a custom visual file? A custom visual file is used when none of the pre existing visuals fit the business needs. Custom visual files are generally created by Developers which can be used in the same way as prepackaged files. 4. What are the various type of users who can use Power BI? Ans: PowerBI can be used by anyone for their requirements but there is a particular group of users who are more likely to use it: Report Consumers: They consume the reports based on a specific information they need Report Analyst: Report Analysts need detailed data for their analysis from the reports Self Service Data Analyst: They are more experienced business data users. They have an in-depth understanding of the data to work with. Basic Data Analyst: They can build their own datasets and are experienced in PowerBI Service Advanced Data Analyst: They know how to write SQL Queries and have hands-on experience on PowerBI.

Business Analyst vs Data Analyst

Majority of top companies hiring for analytic roles (Data Analyst/Business Analyst) focus heavily on SQL understanding as a selection criteria, which according to me, should be the first thing you start your preparation with. I have divided this SQL roadmap into 3 steps (Basics, Level Up & Practice), and it should take around 1 month to complete. Step 1 - Basics 🔢 : ➡What is a Relational Database / RDBMS? ➡SQL Data Types - Varchar, text, int, number, date, float, boolean. ➡SQL commands - select, where, like, distinct, between, group by, having, order by, insert into, case when, update, truncate, delete, commit, rollback (basically all the DDL, DML, DCL, TCL commands in SQL). ➡Integrity Constraints - Primary key, foreign key, not null, unique. ➡Operators arithmetic, logical, and comparison operations. ➡Use of distinct, order by, limit, and top. ➡Use of union and union all. ➡Joins in SQL inner, left, right, outer, self, full outer, cross join. Step 2 - Level up ⬆⬆ : ➡Normalization in SQL ➡Aggregate, date, and string functions ➡Sub-Queries ➡CTE table / with clause ➡In-built SQL functions ➡Window functions ➡Views Step 3 - Practice SQL Questions on leetcode & hackerrank ✅ Hope it helps :)
