Architecture of Power BI

The Microsoft Power BI architecture follows four major steps encompassing the entire process, starting from data sourcing to creating reports and dashboards. These steps involve various technologies and processes working together to deliver accurate results. Let us understand these steps in detail:

Data Acquisition and Transformation:

This initial step involves sourcing data from multiple data sources, such as databases, spreadsheets, or cloud services. Power BI supports a wide range of data connectors that facilitate seamless integration with these sources. Once the data is acquired, it undergoes transformation and cleansing to ensure its quality and relevance. Power Query, a Power BI data modeling component, enables users to shape, clean, and combine data from different sources.

Data Modeling:

The next important step is data modeling once you have transformed the data. Power BI involves using an advanced in-memory engine known as Power Pivot. It empowers users to build data models by establishing connections between various tables. Moreover, users have the flexibility to create calculated columns, measures, and hierarchies to enhance the functionality of the data model. Power BI Desktop, a Windows application, is widely utilized to perform these tasks.

Report and Dashboard Creation:

Users can design visually appealing reports and dashboards using Power BI Desktop once the data model is prepared. This tool offers rich visualization options, including charts, graphs, tables, and maps. Users can customize these visualizations, add interactivity, and apply filters to create dynamic and informative reports. Power BI also provides features for advanced analytics, such as the ability to incorporate machine learning algorithms or write custom DAX expressions.

Report Publishing and Collaboration:

The final step involves publishing the reports and dashboards to the Power BI service. Users can publish their reports securely on the Power BI service, a cloud-based platform. This platform permits sharing reports with internal and external parties, maintaining data confidentiality. Collaboration features, such as commenting, sharing, and embedding, are available on the Power BI service, facilitating teamwork and the collection of valuable feedback.
