SEMINARS AND WORKSHOPS

The workshop, Data Cleaning and Dashboard Creation Using Power BI, provided a hands-on learning experience for students to develop their data preparation, transformation, and visualization skills. It was organized for MCA students to learn the experiences of Power BI for data-driven decision-making.

Topics Emphasized:

• Understanding Power BI
  The session began with an overview of Power BI, covering its core components such as Power Query, Data Modeling, and the Visualization pane. Participants were introduced to its intuitive interface and its broad range of business intelligence capabilities.
• Data Cleaning Techniques

• • Importing Data: The session demonstrated how to import data from multiple sources, including Excel, CSV files, and databases.
