Analytics is a scorching hot topic today, which is scarcely surprising since we live in a data-dominated age. Analytics deals with discovering, interpreting, and processing data. But data and business analysts have a multitude of tools to choose from, and it can be challenging trying to decide which is the best fit for which project.
Today we will do our part in helping make that decision easier by focusing on Power BI, an analytics tool created by Microsoft.
Let’s get started with the basics of Power BI before understanding how to learn Power BI.

What is Power BI?
When looking for the answer to “What is Power BI?”, we need to look no further than the tool’s creator, Microsoft. The company defines Power BI as “…a collection of software services, apps, and connectors that work together to turn your unrelated sources of data into coherent, visually immersive, and interactive insights.”
The BI stands for “business intelligence,” and the tool gives non-technical users all the resources they need to aggregate, visualize, analyze, and share data. The business world considers Power BI one of the best drag-and-drop tools available in the industry today.
While we’re at it, we should define business intelligence. According to CIO, business intelligence “…leverages software and services to transform data into actionable insights that inform an organization’s strategic and tactical business decisions.” The tools access and analyze relevant data, then offer findings via charts, reports, graphs, summaries, maps, and dashboards, to provide users with accurate and detailed intelligence regarding the state of the company.
In summary, business intelligence uses tools to take raw data and turn it into smart plans and actions that can benefit a business on many different levels—Power BI is one such tool. If you want to learn more about business intelligence, there are plenty of business intelligence courses to choose from.
After going through about Power BI, you can begin learning Power BI by first understanding about DAX.
What is DAX in Power BI? What is it Used For?
As you begin to learn Power BI, you will inevitably encounter the term “DAX.” It stands for “Data Analysis Expressions,” and is a collection of constants, functions, and operators developed by Microsoft and used in select BI and data visualization tools. DAX is also called a function language because the full code resides inside the functions.
DAX is used to manipulate data and helps you define the custom calculations used in calculated fields and calculated columns, working with relational data, and performing dynamic aggregation. Put differently, DAX enables users to create new information from data that already exists in your model.
DAX uses some of the same functions as Excel, so if you are familiar with the latter, you may find DAX easier to use. It offers a higher degree of flexibility, letting users create formulas that are applied on a row-by-row basis.
Note that while DAX offers greater strength and flexibility to your data models, it runs the risk of making them overly complicated. Also, DAX comes with a steep learning curve, so be sure you want to work with it before committing.
Next, let us go ahead and learn Power BI by understanding its vast potential.
BI’s Vast Potential
Since Power BI is so versatile and packed with useful features, professionals in many different roles use it, including:
- Professionals (accountants, sales professionals, marketers)
Power BI facilitates intelligent decision making, reducing the likelihood of failure, and mitigating inherent risks. The data that BI processes is available for viewing and interaction 24/7, anywhere you have mobile access. This convenient feature means that users can pull, process, and share real-time data anytime, anywhere.
Data security is a big concern today, and Power BI lets users track and control data usage, granting access only to those who should have it. No need to bother tech support or other IT security elements in your business—the Power BI dashboard lets you regulate usage efficiently and effectively. Power BI also offers the flexibility of storing the data in Microsoft’s cloud, or safely behind your company’s firewall.
The bottom line, Power BI lets users view real-time data anytime and anyplace, create reports based on that new information, and send off specific datasets to the appropriate groups. Power BI uses the extremely popular Office 365 as its platform, which means you can use the latter’s interface for fast and easy implementations.
Lastly, Power BI is scalable, so it can fit any organization and handle changes in size, either a rapid business expansion or an unexpected downsizing.
In summary, here’s a list of Power BI’s advantages:
- It’s easy to use
- It lets you access over 70 data connectors
- It’s one of the most cost-effective, inexpensive solutions available
- It offers interactive visual dashboards
- It is easily accessible from anywhere
- It provides data sharing and collaboration
- It supports natural language search
