    Power BI and Tableau are two popular data visualization tools that primarily focus on business intelligence (BI). They collect data from heterogeneous sources, integrate data, analyze the integrated data, and create visually immersive insights out of it. In other words, Power BI and Tableau help users to perform data analysis, data manipulation, and data visualization to make the most out of the business data. This article intends to draw a detailed comparison between Power BI and Tableau so that it becomes easy for you to pick the best data visualization tool that fits your requirements. Also, it walks you through the features, advantages, and disadvantages of both Power BI and Tableau. So without further ado, let’s get started!

    What is Power BI?

    Power BI is a widely used data visualization software developed by Microsoft that primarily focuses on business intelligence. It is a suite of software applications, services, and connectors that work collectively to transform data from heterogeneous sources into interactive and visually appealing insights. Data may be from an excel spreadsheet, database, webpage, or cloud-based or on-premises data warehouses. With Power BI, you can quickly and easily connect to your data sources, analyze the data, convert it into visually immersive insights, and share those insights with anyone you wish. This data visualization tool is a part of the Microsoft Power Platform. The Power BI ecosystem consists of multiple components that are as follows:

    • Power BI Desktop

    The Power BI Desktop is a Windows-based desktop application for creating reports.

    • Power BI Service

    The Power BI Service is a Software-as-a-Service (SaaS).

    • Power BI Mobile Apps

    The Power BI Mobile Apps is an application for Android, iOS, and Windows devices.

    • Power BI Report Builder

    You can create paginated reports using The Power BI Report Builder and share them in the Power BI Service.

    • Power BI Report Server

    The Power BI Report Server is an on-premises report server for publishing your reports created in the Power BI Desktop.

    • Power BI Gateway

    The Power BI Gateway synchronizes external data in and out of Power BI.

    History

    Thierry D'Hers and Amir Netz first introduced the Power BI software in 2011. They both were part of the SQL Server Reporting Services at Microsoft. However, Ron George originally designed Power BI in 2010 and named it Project Crescent. Project Crescent was available publically and bundled with SQL Server Codename Denali. Later, Microsoft renamed Project Crescent to Power BI and unveiled it in September 2013 as Power BI for Office 365. The Power BI’s first release was based on Microsoft Excel’s add-ins, namely Power Query, Power Pivot, and Power View. Microsoft added many other advanced features to Power BI, such as enterprise-level data connectivity, Questions and Answers, security options via Power BI Gateways, and many others. In July 2015, Microsoft released Power BI to the general public for the first time.

    What is Tableau?

    Tableau is also a popular data visualization tool with a primary focus on business intelligence. It is a leading end-to-end visual analytics platform that is transforming the way businesses and organizations are using data. It provides them an easy and quick way to explore and manage data, discover insights from it, and share them with others. The tools in Tableau for data analytics are categorized into two groups, namely developer tools and sharing tools. Let us briefly talk about these two categories below.

    Developer Tools

    The developer tools are the tools used for creating dashboards, reports, visualization, and charts. Tools that fall under this category are the Tableau Desktop and the Tableau Public.

    • Tableau Desktop

    The Tableau Desktop enables you to create reports and charts and blend them together to create an interactive dashboard. In addition, it provides connectivity to data warehouses and other data sources for live data analysis.

    • Tableau Public

    The Tableau Public is a free version of Tableau with some limitations. With this version, you can save your creations only on Tableau’s public cloud. This version is best for those who wish to learn Tableau.

    Sharing Tools

    The sharing tools are the tools used for sharing the charts, visualizations, reports, and dashboards created using the developer tools. Tableau products that fall under this category are Tableau Online, Tableau Server, and Tableau Reader.

    • Tableau Online

    This is an online sharing tool, having functionalities similar to the Tableau Server, but the data is stored on the server hosted in the cloud.

    • Tableau Server

    The Tableau Server enables users to share visualizations created in the Tableau Desktop across their organizations. However, before sharing the visualizations, you must first have to publish them in the Tableau Desktop.

    • Tableau Reader

    The Tableau Reader lets users view visualizations created using Tableau Desktop or Tableau Public.

    History

    Tableau was introduced as a computer science project at Stanford that intended to improve the flow of data analysis and make data more accessible to people through visualizations. Pat Hanrahan, Chris Stolte, and Cristian Chabot are the founders of Tableau. They developed Tableau’s foundational technology, VizQL.
