Completed hands-on training in Data Analysis, SQL, and Power BI, with a strong focus on applying analytical skills to real-world business scenarios. Developed practical experience in cleaning, transforming, querying, analyzing, and visualizing data to identify trends, patterns, and actionable insights.
Data Analysis: Worked with real-world datasets to clean and organize data, identify inconsistencies, perform exploratory analysis, calculate key performance indicators (KPIs), and interpret results to support data-driven decision-making.
SQL: Gained hands-on experience writing SQL queries to retrieve, filter, join, aggregate, and analyze data from relational databases. Practiced using SELECT statements, JOINs, subqueries, GROUP BY, HAVING, CASE statements, aggregate functions, and window functions to answer business questions and generate meaningful insights.
Power BI: Built interactive dashboards and reports by importing and transforming data, creating relationships between tables, developing DAX measures and calculated columns, and designing visualizations that communicate key findings clearly. Practiced creating dashboards for tracking KPIs, trends, performance, and business metrics.
The training emphasized a practical, project-based approach, combining SQL analysis with Power BI visualization to take raw data through the complete analytical process—from data preparation and querying to dashboard development and presentation of actionable insights.
