Power BI vs Tableau: Full Comparison [2023]

Introduction

The new world of data visualization is emerging at a fast pace with new players coming into the market. Business intelligence tools play an essential role for any business team. They provide ease to collect, store, and visualize several types of data to end-users. The two most popular Business Intelligence tools are Power BI and Tableau.

Currently, they are the market leaders in the Business Intelligence society. This blog helps you understand the essential features of both the tools, their products, the pros and cons of both of these tools, and Power BI vs. Tableau.

What is Power BI?

Power BI is a leading BI tool for data analytics, creating data visualization, and preparing ad-hoc reports that give a multi-perspective view of the dataset. You can handle data from different sources after the cleaning (data cleaning involves steps like importing data, transforming data to tabular format, splitting up columns, removing unnecessary rows, and unpivoting the region columns) and integration (data integration means aggregating data from various sources and creating a single data model for analysis) process. It allows you to view, visualize and analyze the data. It uses powerful compression algorithms to import data in.PXIB file. It provides multiple software services, over 100 connectors, and a drag-drop feature, increasing ease of use. Dashboards generated are practical and easy to understand. Power BI uses Microsoft systems like Excel, Azure, and SQL, making it an easy win for those already using Microsoft products.

Features of Power BI

• Power BI can spot trends in real-time, which helps to identify issues and improve its performance.
  
• It is easy to use Power BI due to its simple interface.
  
• Power BI has auto-search capabilities. You can ask questions, and its Q&A feature will quickly answer your questions which lets you explore your data in your own words.

Power BI vs Tableau: Key Differences

Power BI is easy to learn as compared to Tableau.

• It allows you to create new columns, delete unnecessary columns, modify data, change formats, etc., but Tableau allows you to work on pre-processed data itself. Users can alter the data type and split columns, but they cannot remove unnecessary columns.
• Power BI focuses on the “flow” to have a smooth and consistent user experience. On the other hand, Tableau focuses on coding to provide you with new visual effects which third parties create.
• Power BI uses DAX for calculating and measuring columns, while Tableau deploys MDX for measures and dimensions.
• Power BI offers PowerPivot dots (user to perform efficient data analysis) more user-accessible, but Tableau does not provide this.

Power BI vs Tableau: Tabular Difference

Let’s look at some more differences between Power BI and Tableau.

Advantages of Power BI

• Power BI is an affordable tool. The Power BI desktop is free of cost, you can create datasets, dashboards, and reports for yourself and share them with your co-workers for their analysis, but for sharing reports on the cloud, you need to pay 9.99$ per user per month.
  
• It is easy to use. If you have intermediate knowledge of Excel, you can go on with using this tool.
  
• Microsoft comes up with updates for their software monthly, and so for Power BI. Users can experience newly developed features frequently.
  
• With Power BI, you can access data from different data sources from anywhere and anytime multiple times.
  
• Power BI comes up with interactive dashboards, and users can filter, highlight features, etc., in a single click. 
  
• The query editor in Power BI helps to modify data files before they are actually loaded into the Power BI.
  
• Power BI provides quick deployment in a secured environment. It can also integrate with Python and R language for using visualizations.

Disadvantages of Power BI

• The Power BI desktop version is not compatible with iOS. 
  
• It has a clunky interface filled with many icons that may block the view of reports and dashboards.
  
• It does not accept a file size greater than 1GB.
  
• Sometimes it becomes difficult to process larger datasets with complex features because Power BI may crash in these situations.

Advantages of Tableau

• Tableau provides you with online resources, guides, training, and an online forum, making the Tableau community more engaging.
  
• The software upgrades in Tableau are easy to be carried out.
  
• The overall performance of this tool is high and secure. Tableau can create different kinds of visualizations in one shot.
  
• It is possible to handle a large amount of data with Tableau.
  
• Users are allowed to incorporate Python or R for performing complex table calculations.

Disadvantages of Tableau

• Tableau does not provide an automatic option for refreshing reports, which increases manual efforts to update data in the back-end.
  
• Tableau does not provide you with version control which means you can’t get back to the previous level of data once the reports and dashboards are published.
  
• Tableau has a limit of 16 column table display, so users sometimes find difficulty in displaying data for larger tables.
  
• Tableau has static parameters, you can only select a single value using a parameter, and whenever the data is changed, these parameters are manually updated and not automatically.

Tableau or Power BI: Which one is better?

Both the tools have their own specific features. To select between these two, one needs to think about parameters like which person will use the tool (stakeholders or data analysts), what are their requirements, the size of the organization using the tool, the volume of data being used, etc.

Power BI comes up with intuitive features, therefore it is easy to learn. So it can be used by stakeholders who don’t have much knowledge as data analysts but want to do data analysis. In the case of Tableau, the interface is not very intuitive; therefore, quite challenging to learn. So, it can be used by data analysts who know data science and visualizations.

So, Power BI is better for its ease and Tableau for its speed and additional capabilities.

There are several parameters to be considered before going with one of the two. The ultimate goal is to gain valuable insights from the data and to achieve this,  the technicians should choose the one wisely.
