Data Analysis Dashboard
Interactive dashboard using Tableau/Power BI to analyse data and provide meaningful insights.
1. Project Overview
Interactive dashboard using Tableau/Power BI to analyse data and provide meaningful insights.
2. Problem / Challenge
Transforming complex multi-source datasets into intuitive visual dashboards for decision-makers.
3. Approach / Methodology
Cleaned and modelled data using SQL, designed calculated fields and interactive visualisations in Tableau and Power BI.
4. My Contribution
Built custom dashboards with drill-down capability, automated reporting workflows, and documented analytical insights.
5. Results / Outcome
An interactive dashboard built with Tableau and Power BI, using SQL to prepare and query the underlying data. The dashboard presents the data visually so that patterns can be explored directly rather than read from raw tables.
6. What I Learned
This project built practical experience writing SQL for analysis — joins, grouping and aggregation — and in designing dashboards around the questions a reader actually wants answered rather than displaying every available field. It also highlighted how much of dashboard work is data preparation rather than visualisation.
