Data Scientists vs Data Analysts
November 5th, 2019
Data is an important tool to many, if not all, businesses. Business Intelligence (BI) software can help organisations make sense of all the data they collect, and allows them to make better, more informed decisions. It has been estimated that by 2020 the business intelligence market will grow to be worth $22.8 billion.
There are plenty of BI tools on the market but there seems to be three main contenders that people use: Microsoft Power BI, Tableau and QlikView. But which is better?
“Power BI is a business analytics solution that lets you visualize your data and share insights across your organization, or embed them in your app or website. Connect to hundreds of data sources and bring your data to life with live dashboards and reports.” (Source: https://powerbi.microsoft.com/en-us/what-is-power-bi/)
Power BI, launched in 2015, gives users a more interactive way of understanding data with visualisations, with the ability to render analytics reports.
“Harness the power of your data. Unleash the potential of your people. Choose the analytics platform that disrupted the world of business intelligence. Choose Tableau.” (Source: https://www.tableau.com/en-gb)
Dubbed the most popular tool for business intelligence on the market, Tableau gives the user the ability to create, display and share interactive reports.
“The modern analytics era truly began with the launch of QlikView, our classic analytics solution, and the game-changing Associative Engine it is built on. It revolutionized the way organizations use data with intuitive visual discovery that put business intelligence in the hands of more people than ever.” (Source: https://www.qlik.com/us/products/qlikview)
QlikView, a product by Qlik, is an end-to-end ETL solution, allowing users to create data visualisation, charts, tables and statistical analysis.
I recently ran a survey to find out which Business Intelligence tool my network prefers. Through a mix of questions there was one clear winner.
Which is best for Data Visualisation?
Which is best for Analytics?
Which is best for Online Analytics Processing (OLAP)?
Which is the best for Document Management?
Other: Azure, SharePoint, MicroStrategy
Which is best for Decision Services?
Which is best for Integrations?
Which is best for Big Data Integrations?
Power BI vs Tableau vs QlikView – overall winner
It’s clear from these results Power BI is winning on the user front of Business Intelligence tools with over half of those surveyed stating it the best in each separate category. As one respondent puts it:
“Power BI is rocking right now, so friendly and tons of data source integrations with on-premises and cloud”
Here at KDR we use Power BI for most of our reporting, using a variety of tabs to visualise the weekly, monthly and quarterly KPIs, with each member of the team being able to see this and easily understand their data. You can read more about how we use Power BI and Data Visualisation in our e-magazine: Information Matters – Data Visualisation vs Traditional Reporting.
It’s interesting how Power BI seems to have taken over Tableau as the most popular BI tool these days – now we don’t profess to be the absolute knowledge hub for BI surveys, but the results are telling. Power BI is the users favourite which correlates to the fact that we have seen a trend in our clients wanting to hire BI professionals with Power BI experience over Tableau.
Will Power BI continue to reign supreme or will one of the others take the throne? How will Salesforce’s recent purchase of Tableau affect the market? Or Google’s new baby, Looker? What can we expect to see in the next 5 years? It certainly is an exciting time for this side of Technology!
