My First Data Analytics Portfolio Project with Power BI
I started my self-paced journey of learning Power BI 2 weeks ago and have built my first Power BI Report. I started from knowing nothing about data engineering and data analytics to learning a lot along the way. Power BI is a great tool for deriving insights and building narratives/stories from your raw data.
Why Power BI?
Power BI is a Microsoft application for loading, modeling and visualizing data. Our goal with power bi is to build dashboards that visualize and explains data to end user. Power BI provides each visual for a different purpose for free and also provides support for importing custom visuals. They make our report more appealing.
Power Bi is free to get started with. You don't require to sign up to build a report but if you wish to publish your report you need to have a Microsoft account.
Power BI allows users to load data from various sources and the power query editor makes it use to clean, filter and query data. Power BI Query provides a lot of different options to enrich our source data.
Power BI supports a 3-step process.
Connect to your Data Source and filter, and clean your raw data if needed
Build relationships within the table/query to build a data model.
Create reports that stand out with the help of this data model
