Welcome to our guide on “What is Power BI,” where we delve into Microsoft’s revolutionary BI technology. Let’s build a strong understanding of its basics before diving deeper. Whether you’re acquainted with data visualization and business intelligence or not, in today’s data-centric world, comprehending these concepts is pivotal.
Think of data as a treasure trove of insights that drives astute business decisions. Before we proceed, let’s briefly explore Business Intelligence (BI) – the process of refining raw data into actionable information, culminating in illuminating reports and graphics.
Data visualization, the art of representing data graphically, conveys essential information through charts, graphs, KPIs, and maps. Enter Microsoft Power BI, an influential tool that equips businesses with intelligence and captivating visuals for empowered decision-making. Join us as we unlock the potential of Power BI.

It is a Microsoft cloud-based business analysis and intelligence service. It is a set of business intelligence and data visualisation tools that includes software services, apps, and data connectors.
We can use the datasets imported into Power BI to create sharable reports, dashboards and apps for data visualisation and analysis. Power BI is an easy-to-use tool with impressive drag-and-drop functionality and self-service capabilities.
Microsoft provides three Power BI platforms:
We can also deploy it on both on-premise and cloud platforms.
Let us now go over a few reasons why Power BI is such a unique tool in today’s world and why we need it:
Power BI is a Microsoft product first released on July 11, 2011. Ron George designed and created it in 2010 and released it under the name “Project Crescent.” Later that September, Microsoft changed the name to Power BI and made it available to the public.
Power BI for Office 365 release included Microsoft Excel add-ins, Power Pivot, Power View, and Power Query. Microsoft then comes up with the latest features like natural language Q&A, enterprise-level data security and networking, Power data gateways, and so on.
On July 24 2015, Power BI’s first public release happened. According to the 2019 Gartner Magic Quadrant for Analytics and Business Intelligence Platform, Power BI is one of the leading BI tools.

The most unique and curious features of Power Bi are:
It is a Microsoft business intelligence and data mining software suite that includes a variety of services. These services each serve a specific purpose and work in tandem to ensure that Power BI functions as a whole. Here, we will learn about each of these services or components, as well as their functions.
We use Power Query to access, search, and transform public data or local/internal data sources.
We can import data in many formats from different data sources. It gathers (extracts) data from many data sources and converts it into a regular format during the data integration step. It stores data in a familiar storage location, later integrated into Power BI.
After it integrates and stores data in a safe location, had processed the raw data. Several processing or cleansing operations, like removing redundant values, modify the raw data. Later, we apply relevant business rules to the processed data that converts it to meet our business requirements. The processed data had moved into data warehouses. It completes the ETL process.
In this final phase, the processed data had moved from the warehouse to Power BI platforms such as Power BI Desktop used to create reports, dashboards, and scorecards. Power BI provides a diverse set of visualizations. We may also use the marketplace to import custom visualizations. We can publish reports on the web or mobile apps using the report development platforms to share them with other company users.
According to the motto of usage, divided into four types of users:
Analysts use Power BI to create reports, dashboards, data models, and review to find unique insights from the data. Power BI provides a variety of data sources from that analysts can extract data, create a dataset, cleanse, and prepare that data for use in reports and analysis.
They are regular users who analyze the reports and dashboards obtainable via the Power BI website or mobile app. Business customers are up to date on the most recent information, which allows them to make different decisions on time. They can configure an alert message change in data or anomaly (in case required).
They are primarily concerned with data scalability, availability, security and handle all Power BI services and users from a single location.
They are in charge of all technological tasks. Their primary responsibilities include building custom visualizations for use in Power BI, embedding Power BI into other programmes, creating reports, and so on.

There are numerous data sources from which you may extract data for use in Power BI. You can connect to local data files, Excel files, Azure SQL Database, Facebook, Google Analytics, Power BI datasets, and so on.
Gateways, online services, direct connections, and other methods had used to connect to cloud-based and on-premises data sources. We’ve included a list of some regularly used data sources below.
We’re sure you’ve grown fond of Power BI now that you’ve seen everything it has to offer. As a result, you’d want to know its pricing and licence charges as well. In this Power BI course, we will discuss the costs and features of various versions. Microsoft has released three Power BI price plans:
Power BI Desktop’s basic version is free and provides tools for data visualisation, preparation, purification, data modelling, and publishing reports to Power BI Service.
Power BI Pro is available for a monthly membership fee of $9.99 per user. Before purchasing the subscription, you can sample it for free for 60 days. This Pro package offers data collaboration capabilities, a 360-degree real-time view for dashboards, data governance, and the ability to publish reports anywhere.
Power BI Premium costs $4,995 per month for one dedicated storage resource and cloud computing facility.
In this part, we will go over a Power BI case study in detail. It will assist us in comprehending the role of Power BI in a real-world environment. Rolls-Royce is the case at question here. This 20-year-old enterprise is self-explanatory.
As of this year, it is producing over 13,000 engines for commercial aeroplanes all over the world. It reflects the company’s more ever-expanding consumer base. Let’s take a step forward and look at the issues faced by the organisation and how Power BI proved to be effective.
The company’s most fundamental challenge was to cut down maintenance costs, operational costs, gasoline prices, and so on. It is only possible if the corporation can record, access and analyse the data generated by all the aircraft’s systems and equipment. With the advancement of technology, the systems can record an increasing number of signals, data from various aircraft sensors.
As a result, data volumes have continually increased. As a result, the organisation needs efficient data management and analysis system capable of filtering vital signals or data and utilising it to produce insights.
In addition, Rolls-Royce introduced the “TotalCare Services” customer service and maintenance strategy. It was a very successful venture that provided the consumer with engine maintenance services. The organisation also required sufficient data insights to develop a bond with their clients.
Rolls-Royce chose Microsoft Azure and Power BI to manage and analyse terabytes of engine and maintenance data. With the assistance of Microsoft Azure, the organisation was able to collect data from a variety of locations and sources. They were also able to use Microsoft Power BI to evaluate the collected data.
They used Power BI to create dashboards and reports that included relevant visualisations and charts. It used to take a long time to create meaningful reports to gain insights into data. Using Power BI, on the other hand, is the slightest step in the entire process. Finally, it is vital in providing critical data insights so that the company can focus on improving operational efficiencies and developing long-term partnerships with its customers.
To install Power BI, one can follow the listed ways below:
After installing Power BI Desktop, you may now sign in to your account on the Power BI service online. In case of a new user, scroll down and sign up for free with your student or work email address.
If you don’t already have a student or work email address, you can sign up for a Microsoft trial account by going here.
Let’s run Power BI Desktop after installed and study the application’s primary components.
As previously stated, the “Get Data” option allows you to import data of varying sizes from multiple platforms. You can get all of the materials for this tutorial by clicking here.
Open the “SalesData.xlsx” excel file, pick the In-Stock Datasheet from the left side of the window, and then click Transform Data. You had navigated to the Power Query Editor as a result of this. It allows to go through and transform the data.
Excellent! Now we loaded our data, let us start cleaning it.
We notice that the first row, columns 9 and 10, contains null values after viewing the In-stock data. Values like this slow down our model’s overall performance, so let’s clean it out. You can remove the rows and columns by selecting the “Remove Rows” and “Remove Columns” options.
After we do this, we can see that our column name appears in the first row of our data. So let’s make a change by clicking the box next to “Use first row as headers.”
Click “Close & Apply” in the top left corner of the Power Query Editor’s home section to confirm that changes are applied.
One can change the data types of a column by selecting the data view button on the left side of the window.
Cleaning our data can be a time-consuming and laborious task. We have fundamental ways of dealing with data that contains certain irregularities, and there is much more to it.
