What does Power BI do?
Using Power BI, a business analytics service from Microsoft, Data is transformed into visual insights. Users connect to numerous data sources to generate interactive charts, graphs, and dashboards. Advanced computations are possible with its DAX language, and analysis is made easier using natural language queries. Tools for collaboration allow for secure report sharing and real-time interaction. Data modeling, Power Query, and integration with Microsoft services all improve data processing. Power BI provides a variety of editions, including Desktop, Pro, and Premium. It enables organizations to take well-informed decisions, promoting the expansion of data-driven businesses.

Power BI Dashboard
A Power BI dashboard also known as a canvas, tells the story through visualization. A well-designed dashboard only includes the key components of the story because it can only fit on one page. The dashboard's visualizations are called tiles. These dashboard tiles are pinned from reports. A dashboard's visualizations are derived from reports, and each report is as per one data set. On-site and cloud-based data can be combined in a dashboard. No matter where the data is located, they are offering a consolidated view.


Features of Power BI

  • Stream Analytics:
    The main benefit of Power BI is its capabilities for stream analytics. With the help of Power BI, real-time analytics can be performed on data from social media and industrial sensors to make quick decisions.
  • Multiple Data Sources:
    One of Power BI's key features is support for various data sources. To generate interactive visualizations, you can access a variety of data sources, including Excel, CSV, SQL Server, Web files, etc.
  • Custom Visualization:
    Power BI's default standard may not be adequate in some circumstances when working with complex data. In that situation, you can access the custom visualization library that suits your requirements.

Power BI Architecture


The Power BI architecture includes three steps. The data handling process which is used in the first two phases is called ETL (extract, transform, and load).

Data Integration: The data that comes from various sources must be handled by an organization. The data will be first extracted from various sources, like your personal databases, servers, etc. The data is then stored at a shared space class as the staging area and is integrated into a standard format.

Data Processing: As processing is required before the data can be presented, the integrated data is not suitable for visualization. This data has been pre-processed.

For example, from the data sets, any duplicate or missing values would be removed.

Once the business rules are applied to the data, it will be turned into presentable data. The data warehouse will then be loaded with this data.

Data Representation: The many visualization tools that Power BI offers can be used to visualize the data considerably more effectively after it has been loaded and processed. With the dashboard and reports, our data representation is more understandable. The insights provided by these visual reports can be used by business end users to make decisions.

Components of Power BI

Following are the components of Power BI:


1. Power Query: This is used for searching, transforming, and accessing both internal and public data sources.

2. Power Pivot: Power pivot is a tool for in-memory analytics that is used in data modeling.

3. Power View: The data can be analyzed, visualized, and displayed using the power view to create an interactive data visualization.

4. Power Map: This interactive geographical visualization tool brings the data to life.

5. Power BI Service: Workbooks and data views that have been recovered from on-premises and cloud-based data sources can be shared.

6. Power BI Q&A: With the natural language query, you may ask any question and receive an immediate answer.

7. Data Management Gateway: You can expose tables and view data feeds as well as receive periodic data refreshers.

8. Data Catalog: You can locate and reuse queries by using the data catalog.
