Before we dive into the introduction to It, let’s take a quick look at business intelligence (BI). It refers to taking raw data from a data source, converting it into usable data, and using it to make informative reports and graphs for data analysis.

The graphical representation of tabular data is known as data visualization. It allows the user to visualize important information through charts, graphs, KPIs, maps, etc. For valuable information just by looking at it. Well, Microsoft It is a tool with business intelligence and data visualization capabilities.

What is Power BI ?

It is Microsoft’s cloud-based business intelligence and analytics service. It is a suite of business intelligence and data visualization tools such as software services, applications, and data connectors. We can use imported datasets in It to visualize and analyze data by creating shareable reports, dashboards, and apps. It is an easy-to-use tool that offers great drag-and-drop and self-service capabilities.

Microsoft offers three types of It platforms:

  • It Desktop (desktop app)
  • It (SaaS i.e. Software as a Service) service
  • It Mobile (for iOS and Android)
  • In addition, we can implement It on both on-premises and cloud platforms.

In the image below, take a look at the process flow in It.

Why Power BI?

As we learned in the previous section of the It tutorial, It is an umbrella term that has several different types of services under its umbrella.

  • There is a cloud-based BI service called It Services that is used to display and share dashboards.
    A desktop-based reporting interface known as It Desktop.
  • Another useful service is It Embedded which runs on Azure cloud platform and we can use it for reporting, ETL and data analysis.
  • Also, let’s discuss some points about why It is such an important tool today and why we need it.

Real-time analytics can be done in It by creating direct connections to data sources. Also, it preserves the data till the last second with Data Refresh.

You can use custom visuals from custom gallery. Custom images are divided into many options and categories.
Quickly find important information and data sets within your data with the Quick Info option.

Create a direct or indirect connection to local data sources such as SQL Server and use a secure channel to access data through data gateways. This makes It enterprise-ready, because on-premises connections make data transmission secure and the technology scalable and reliable.

You can connect to other services through It, such as SQL Server Analysis Services (SSAS), Microsoft Excel, etc.

It is a new modern software that uses the latest technologies such as HTML 5.0, column storage databases, cloud computing, mobile applications, etc. This helps keep It ahead and popular as it is constantly updated with the latest features.


It is a Microsoft product that was initially released on July 11, 2011. It was originally designed and created by Ron George in 2010 who released it under the name “Project Crescent”. Later, in September 2013, Microsoft changed the name to Power BI and released it to the public.

This version was Power BI for Office 365 and had add-ins for Microsoft Excel, Power Pivot, Power View, and Power Query. In the newer versions, Microsoft has added advanced features such as natural language questions and answers, enterprise-grade data connectivity and security, power data gateways, etc.

Power BI’s first public release was on July 24, 2015. As of 2019, Power BI has been officially announced as a Top BI Tool by the 2019 Gartner Magic Quadrant for Analytics and Intelligence Platform.
