What is Power BI? 

"Power BI" refers to various software applications, apps, and connectors that analyse data sources and offer pertinent insights and judgments. Created by Microsoft as a component of their Power Platform and is an approachable option for companies to gather, manage, and analyse enormous amounts of data. Power BI collects data from the sources, automatically evaluates it, and then provides users with pertinent insights, typically as graphs and charts. 



 

Reasons to use Power BI? 

There are many reasons why organisations choose to adopt the Power BI service for their business benefits. Here is a list describing the reasons for Power BI’s popularity:: 

a) Accessibility to datasets from various sources: Organisations can gain access to large volumes of data from various sources by using Power BI. The service basically allows them to view the data, analyse it and visualise massive quantities of data which can otherwise not be opened in Microsoft Excel. Few of the notable data sources available for companies to use through Power BI are Microsoft Excel, XML, CSV, JSON, PDF and more. Moreover, the service also applies compression algorithms designed to import and cache the extracted data into a .PBIX file.

b) Interactive UI/UX features: The Power BI service makes business processes visually appealing for organisations. It offers users with an easy functionality to drag and drop components and various other aspects of the workspace. The service essentially allows them to copy all the necessary formatting across other similar visualisations.

c) Exceptional software integration with Excel: Power BI is designed to help organisations in gathering, analysing, publishing and sharing their business data with other account users who are stakeholders and team members. Any user who is familiar with the Microsoft Office 365 service have the option to seamlessly connect their queries from Excel, data models and reports to their dashboards in Power BI.

d) Accelerated Big Data preparation with Azure: Organisations can seamlessly analyse and share large volumes of data. The Azure Data Lake service   reduces the amount of time consumed to retrieve data-driven insights and enhance the collaborative structure among Business Analysts, Data Engineers and Data Scientists. The Data Lake basically eliminates all complexities pertaining to the ingestion and storage of user data, resulting in a faster operation of batch, streaming and interactive data analytics.

e) Transform insights into action: Organisations can gain data-driven insights and transform them into actions that help them make better business decisions pertaining to their data. Large-scale scenarios involving business strategies have a better chance of coming up with a successful program to make the best decisions. 

f) Stream analytics for data in real-time: Users of Power BI are provided the functionality to perform their data stream analytics in real time. This accelerated process helps them extract the required data from various sensors and sources on social media to gain access to data analytics procedures in real-time. This leverages their decision-making process to optimise their business outcomes. 

Features of Power BI

Power BI offers a myriad of features to its users, which are described in the list below as follows:

Power BI Desktop

Organisations and other users are offered a software at no cost, called the Power BI Desktop, which can they simply download and install. The software allows them to design reports through seamless access to data. Users are not required to carry out advanced levels of report designing procedures or querying skills for building a report.

Stream analytics

Users of Power BI are equipped with the primary advantage of exploiting the software’s support for real-time streaming analytics. Ranging from multiple factory sensors to social media sources, users are provided with complete assistance in real-time analytics of their data in order to make better-informed and timely decisions.

Multiple data sources

Users are given full support for many of their data sources, which is a primary and core feature of the Power BI service. They are allowed to have access to many sources of data like CSV, Excel, Microsoft SQL Server, Web files and more. This native support and integration help users create better and enhanced interactive visualisations. It especially aids users to eliminate any data silos, which are basically sources of data within their organisation which are not connected to any other sources of data. Power BI allows users to utilise the software service’s on-premises data gateway for the purpose of merging or appending their cloud and on-premises sources of data within the same query.

Custom visualisation

Users will be dealing with large volumes of complex datasets from their many data sources. In such scenarios, the default standard of Power BI may not suffice for their operational needs, in which case they can gain access to the customised library for visualising their data as per their business requirements. Moreover, this very library offers users with a rich range of open-source tools to create stellar visualisations with the support of popular JavaScript libraries like jQuery, D3 and also scripts written in the R language.

Advantages and Disadvantages of Power BI
 

Advantages of Power BI	Disadvantages of Power BI
Affordability:  Compared to other cloud service providers, Power BI is inexpensive. You can download and create reports on your computer, as access to the Power BI Desktop version is free. However, charges will be applied if you share your reports on the cloud.	Rigid formulas and large data volumes:  Power BI majorly uses DAX language. This language can be used to perform many actions, permitting you to create multiple customised calculations. But due to its rigidity, it sometimes becomes awkward and inconvenient, resulting in delays and underperformance of the dashboard.   Power BI has set a limit on the size of the data you can thrust in. You need to update from the free version to the paid version for importing data larger than 2GB.   At times it can crash while processing large & complex data files.
Custom Visualisation:  Power BI Visualisation format offers a wide range of custom visualisations for developers to convert your requirements to maps, charts, graphs, etc.	User Interface:  The view of reports and dashboards in Power BI is blocked and looks cramped with many icon options. Also, the Tooltip has limited usability in Power BI.
Excel is Integrated:  With Power BI, you have the option to save data to Excel. Many people tend to have the data in their excel sheet. Hence, data visualisation tools can aid you in explicitly presenting the data using graphs, maps, and charts in excel format. This data will be accessible to you from Power BI regardless of your location & time.	Complex Table Relationships:  Sometimes Power BI can face problems in managing data with complex correlations and structure between the tables. Moreover, you need to focus on directing the data models carefully, enabling Power BI to appropriately distinguish the relations with the tables.
Data Accessibility and Interactive Visualisation:  Power Business Intelligence provides access to all the data sources created while designing the dashboards & reports to interact seamlessly. You are privileged to access the data stored in the centralised location any number of times, from any device, at any time, and anywhere.	Limitation in Excel Integration:  At times, the excel integration is an advantage. But there is a limitation in downloading data, as you can download only up to 150,000 rows of data.
Upgraded Features:  Microsoft provides users with monthly updates. Overall, for data analysis and visualisation, Power BI is an impressive tool.	Compatibility with Mac/IOS:  Mac Users having a Desktop version rejects compatibility with Power BI.
