What is Power BI?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Power BI refers to a suite of business analytics tools by Microsoft for both individuals and enterprise users.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"> You might have encountered tutorials or demos online describing how it is a beginner-friendly, no-code solution with its drag-and-drop approach to creating dashboards and visualizations. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Power BI remains one of the more popular BI tools among analysts as you can create self-service dashboards with enterprise-grade features such as built-in authentication, connection to data sources, and resource scaling. It also encompasses a mobile app version for Windows, iOS and Android operating systems.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Power BI is offered at three tiers. Power BI Desktop is free to download and use, with less functionality than the paid cloud-based software-as-a-service (SaaS) solutions aimed at enterprise users, Power BI Pro and Power BI Premium. Power BI Pro is licensed per user at $120 a year, while Power BI Premium is licensed per cloud compute and storage, starting at $5,000 a month. The Pro and Premium options allow users to publish and access dashboards to the Power BI cloud service, and access reports or visualizations published by other licensed users.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As Power BI is a Microsoft product, existing fans of Microsoft products will appreciate that it is well-integrated within the Microsoft ecosystem of tools, including Teams, Active Directory, and Azure Cloud Computing.\u00a0\u00a0\u00a0<\/span><\/p>\n<p>Check out the following video for examples of other tools data analysts use in the data analytics process:<\/p>\n<style>.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }<\/style>\n<div class=\"embed-container\">\n<p><iframe src=\"https:\/\/www.youtube.com\/embed\/jgXp1EE4Wms\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<\/div>\n<h2 id=\"power-BI-features\"><span style=\"font-weight: 400;\">2. What are the main features of Power BI?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If you\u2019re a beginner to data analytics, you\u2019ll find that Power BI&#8217;s point-and-click interface makes it easy for you to quickly perform advanced analytics without requiring knowledge of Python or <a href=\"https:\/\/careerfoundry.inbearbeitung.de\/en\/blog\/web-development\/how-to-become-a-software-engineer\/\" target=\"_blank\" rel=\"noopener\">software engineering<\/a>. Previous experience or familiarity with Excel is a bonus, as it\u2019s easy to transfer any modeling done in an Excel spreadsheet directly to create dashboards in Power BI.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can share published dashboards and analytic findings easily within Microsoft&#8217;s broader suite of productivity tools: simply publish to Power BI cloud or embed them directly in Teams&#8217; chats. This makes it easier for your key stakeholders and decision makers to access important metrics.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you hold an enterprise license, you\u2019ll find it helpful to be able to easily enable authentication through direct integration with Microsoft&#8217;s own identity provider, Active Directory. As data security is particularly important for these users, it is a significant advantage to configure authentication directly instead of trying to integrate third-party authentication separately.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Analysts working with large datasets will find it easy to increase computing resources with integrated access to Azure Cloud Computing. The Power BI Premium license includes autoscaling, which automates the process of provisioning necessary computing resources which can significantly lower costs.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The platform continues to be well-supported by Microsoft, with new features announced regularly on <\/span><a href=\"https:\/\/powerbi.microsoft.com\/en-us\/blog\/\" rel=\"noopener\"><span style=\"font-weight: 400;\">Power BI&#8217;s blog<\/span><\/a><span style=\"font-weight: 400;\">. As the data science and analytics landscape is constantly in a state of innovation, Power BI&#8217;s product roadmap likely enables you to remain at (or near) the cutting edge of the field.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Power BI supports an extensive range of more than 500 data sources, making it easy to connect data from multiple sources whether on-prem or on the cloud. Data security is maintained through settings at the data source level, with some data sources offering single-sign on (SSO) access through Direct Query, reducing the need for DevOps involvement or knowledge. Row-level security can also be configured to restrict viewer access to certain datasets within a dashboard.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Cortana, billed as Microsoft\u2019s personal productivity assistant, can be enabled within Power BI to allow natural language queries. You can simply state aloud or type any questions to produce simple aggregations from datasets (such as: \u201cwhat was the most popular travel category for last year?\u201d). Cortana can also be used to <\/span><a href=\"https:\/\/docs.microsoft.com\/en-us\/windows\/configuration\/cortana-at-work\/cortana-at-work-powerbi\" rel=\"noopener\"><span style=\"font-weight: 400;\">auto-generate basic dashboards<\/span><\/a><span style=\"font-weight: 400;\">. This is in addition to Power BI\u2019s Quick Insights feature that auto-generates data visualizations based on predefined algorithms to surface anomalous data points, seasonal trends, correlations, and other patterns.\u00a0<\/span><\/p>\n<h2 id=\"how-to-use-power-BI\"><span style=\"font-weight: 400;\">3. How is Power BI used by data analysts?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A typical workflow in Power BI consists of data connection, preparation, exploratory data analysis, modeling and iteration, and reporting.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To begin, import data directly into Power BI through data connectors that connect Power BI to Azure\u2019s data sources, external databases, Python scripts, and <\/span><a href=\"https:\/\/docs.microsoft.com\/en-us\/power-bi\/connect-data\/desktop-data-sources\" rel=\"noopener\"><span style=\"font-weight: 400;\">many more<\/span><\/a><span style=\"font-weight: 400;\">. As your data likely needs to be cleaned and transformed before meaningful exploratory analysis can be performed, you can make use of <\/span><a href=\"https:\/\/docs.microsoft.com\/en-us\/power-query\/power-query-what-is-power-query\" rel=\"noopener\"><span style=\"font-weight: 400;\">Power Query<\/span><\/a><span style=\"font-weight: 400;\">, a graphical user interface (GUI) with predefined transformation functions that applies queries and other options to clean datasets.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Next, you can start building dashboards by dragging and dropping different chart options onto a blank dashboard or a templated report. With a better understanding of the dataset, you can now create more advanced models through statistical analysis or create auto-generated machine learning models with the built-in AutoML feature.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Once published to Power BI\u2019s cloud service, your dashboards or reports are easily accessible by business stakeholders for decision-making, teammates for further iteration, and to adjacent functions in the organization for self-service analytics.<\/span><\/p>\n<h2 id=\"power-BI-limitations\"><span style=\"font-weight: 400;\">4. Limitations and alternatives<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The free Desktop version is limited to installation on Windows computers. Although Mac OS users can still access it through roundabout solutions (including setting up a local virtual machine or via third party applications) this may be too technical to set up for the average user.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Machine learning capability is limited relative to other analytics tools; only the Premium license offers &#8220;AI-powered data modeling&#8221;. This simply means the use of three tools (AutoML, Cognitive Services, and Azure Machine Learning), which offers fairly limited custom machine learning functionality relative to other options.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While there is some integration with R and Python at all license levels, there are a number of limitations at the Desktop tier. Data for visualizations is capped at 150,000 rows or 250 MB, a limit that data scientists will run into quite quickly.<\/span><a href=\"https:\/\/docs.microsoft.com\/en-us\/power-bi\/connect-data\/desktop-python-visuals\" rel=\"noopener\"> <span style=\"font-weight: 400;\">Other potential issues<\/span><\/a><span style=\"font-weight: 400;\"> include low resolution of generated images (72 dpi), a five minute execution time limit, and the images are not interactive or allow cross-filtering.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Power BI shares these limitations with other tools in its category (such as Tableau or\u00a0 Looker). If you\u2019re looking to go beyond PowerBI&#8217;s dashboarding functionality for more complex ML processes\u2014or to build interactive dashboards with more control over the layout and styling\u2014tools like Dash, Streamlit, and Bokeh provide open-source ways to build more complex visualizations and dashboards.\u00a0<\/span><\/p>\n<h2 id=\"takeaways\"><span style=\"font-weight: 400;\">5. Key takeaways<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In this article, we answered the question: what is Power BI?We\u2019ve taken a deep dive into Power BI to understand its widespread adoption by analytics teams across industries. Its low code interface makes it a beginner-friendly option for general business analytics users to quickly create dashboards and reports for sharing.
