Questions & Answers

Q: How do you build a complete data analytics capstone project?

Build the project from start to finish with Power BI, Tableau Desktop, SQL, and Excel. Create dashboards in the visualization tools, solve business problems with SQL queries, and compare the results across the tools before submitting the work to the client.

Q: Which tools are used in this data analytics portfolio project?

The project uses four data analysis tools: Power BI, Tableau Desktop, SQL, and Excel. The SQL portion uses an MSSQL Server database, while the dashboards are developed in Power BI, Tableau Desktop, and Excel.

Q: What does the Power BI portion of the project cover?

The Power BI portion builds the displayed dashboard step by step, including every visible element. It covers different sets of KPIs, secondary KPIs, charts, DAX queries, date tables, backgrounds, and conditional formatting.

Q: What does the Tableau Desktop portion teach?

The Tableau Desktop portion recreates the dashboard with charts, interactive filters, quick filters, sparklines, and KPIs. It also covers calculating year-over-year growth and using LOD calculations.

Q: How is SQL used to validate the dashboards?

SQL queries are used to solve business problems and check the values shown in the Power BI, Tableau, and Excel dashboards. If the results match, the work can be submitted to the client; if they do not, the mismatch signals that something may be wrong in a dashboard.

Q: Which SQL concepts are included in the project?

The SQL work progresses from basic to advanced queries. It includes case functions, decimal functions, GROUP BY, ORDER BY, WHERE clauses, and other functions, and the queries can be used with databases beyond MSSQL Server.

Q: What does the Excel portion of the project cover?

The Excel portion recreates the same dashboard step by step. It covers pivot tables, data summarization, functions, chart design, chart formatting, and the formatting used to produce the final dashboard.

Q: Which software versions are used for the capstone project?

The project uses Windows 11 with a 64-bit operating system, Power BI 2.118 from the June 2023 release, Tableau Desktop 2022.3.0, MSSQL Server Management Tool 19.2, and Excel 2021. For Excel, the presenter recommends using the 2019 or 2021 version to obtain the expected result.
