Power BI vs Tableau: Which is better?

Introduction

Business intelligence (BI) is an integral part of every organization today. Enterprises analyze and visualize data to derive meaningful insights and make informed decisions. According to Acumen Research & Consulting, the global data analytics market is expected to reach USD $329.8 billion by 2030. 

Helping organizations to make the most of their data are business intelligence tools. Power BI and Tableau are two of the most popular platforms in the market. 

Data analysts, data scientists, and CTOs often face a dilemma when evaluating BI tools. Through this blog, we explore the differences between Power BI and Tableau.

We will look at their features and advantages to consider when selecting the right tool for your needs.

What is Tableau?

Tableau is an interactive data visualization tool from Tableau Software built in 2003. It was acquired by Salesforce in 2019. 

Tableau enables organizations to simplify the process of data analysis. It helps users connect data and create compelling worksheets and dashboards without requiring coding or technical knowledge. 

Its intuitive interface and powerful visualization capabilities make Tableau a popular choice among data professionals. 

With more than one million members spanning over 500 user groups, active Community Forums, and programs, Tableau has an active community to help users.

Tableau Features

Some of the key features of Tableau include:

  • Vector maps: The new Tableau versions from 2019.2 V onward comes with vector-based maps that look cleaner and work smoother to explore maps and other geospatial data.
  • Nested sorting: Nested sorting enables users to select the field value used to determine the sort order. 
  • Data Highlighter: Tableau provisions highlighting specific fields or groups to explore data interactively when viewing large volumes of data. 
  • Workbook Formatting: Users can change fonts, theme, and other format settings at the workbook level instead of worksheet level. 
  • Custom Territories: Tableau helps users create custom territories by grouping locations together on a map, in addition to built in territories (example area code or country). 
  • Data blending: Data blending feature allows combining data from multiple sources. This is useful for analyzing related data from multiple sources in a single view. 
  • Data collaboration and data notifications: With Tableau, users can collaborate with team members whether data is on-premises, in cloud, or in a hybrid environment.
  • Toggle view and drag-and-drop: Tableau is a user-friendly tool that enables users to filter data points with a single click and drag and drop fields to visualize data.

What is Power BI?

Power BI is a business intelligence and data visualization tool by Microsoft. The solution was made publicly available in 2015. 

Power BI is a newer technology compared to Tableau, yet a strong competitor in the market.

The data visualization tool empowers users to extract data from a variety of sources, such as Excel, images, tables, etc. Through an intuitive interface, even non-technical users can create insightful reports and dashboards. 

Power BI can be easily integrated with other Microsoft products such as Excel and SharePoint and improve business performance.

Power BI Features

Here are the key features of Power BI:

1. Filtration: In the Power Query, users can easily apply parameters for filtering datasets into smaller parts. They can filter data at multiple levels, including page, report, and visual filters.

2. Refresh: Power BI provides auto-refresh and manual refresh options to show latest, real-time data in reports. Users can define automatic refresh using ‘Scheduled Automatic Refresh’ for datasets.

3. DAX: Dax functions (Data Analysis Expressions) is a language in Power BI. These functions are essentially predefined codes that can perform analytics on data. For instance, create a custom table or column. Power BI offers over 200 DAX functions in its function library.

4. Natural-language query: Power BI provides a unique feature named ‘Q&A’ where users can ask questions in natural language. This AI-based tool ensures that users can interact with simple language and receive related visuals for the question. For example, what are my quarterly sales?

5. Navigation pane: Power BI ensures a great user experience through its navigation pane feature. It has options for datasets, dashboards, and reports which can be used to navigate through dashboard and reports created.

6. Ad Hoc reporting and analysis: Ad hoc reporting helps to generate on-time reports with real-time data from various sources. This provides data-driven answers for business queries, ensuring faster decision making.

7. Online Analytical Processing (OLAP): Integrating OLAP with Power BI enables users to have multi-dimensional layers of data corresponding to different segments of information and have a holistic view of data.

8. Trend indicators: The trend indicators feature as part of KPIs (Key Performance Indicators) in Power BI help users to analyze changes, growth, and downfall in the business/market information.

9. Real-time dashboards: Power BI ensures that any dashboard created by the users can display and update real-time data. A real-time dashboard will automatically update as new data appears in the dataset. 

10. Content Packs: Power BI offers a collection of dashboards, datasets, and reports in ‘Content Packs’ to use and share these elements without having to share underlying reports.
