What is Power BI and why is it important?

By Robert Half on 5 July 2022

In Hong Kong's increasingly crowded marketplace for enterprise reporting and business intelligence (BI) tools, Power BI and SSRS (SQL Server Reporting Services) stand out as two of the most popular products.

But while SSRS retains strong market presence among BI professionals, some industry insiders report that Power BI is quickly gaining ground as the preferred tool for organisational data analysis and reporting.

While SSRS remains in wide use, it’s certainly true that Power BI offers some compelling advantages in terms of both user-friendliness and extensibility.

Here’s a quick rundown of what is Power BI when it comes to features, learning curve and costs.

What is Power BI?

Since both Power BI and SSRS are both part of the Microsoft BI product stack, they don’t compete directly.

Your choice of tool will depend on your IT skillset, the data source(s) used, the reporting audience, and how that audience prefers to consume its reports.

Power BI was first released in 2015, and has quickly gained popularity as a full-featured BI suite suitable for general business users and BI developers alike.

It can connect to a wide variety of data sources using various connection methods.

Its users can build reports using a drag-and-drop interface, and create personalised dashboards that provide a real-time, 360-degree view of the business.

Applications

Power BI is a full-service tool which can handle everything from data collection to data visualisation.

It is the more powerful option if you want to do dynamic data exploration, allowing you to slice, dice and filter data across multiple visuals with a few clicks.

Data types

Power BI is much more flexible, being able to source and process data from Excel, structured and unstructured databases, Microsoft Azure products, and online/cloud services such as SharePoint and Dynamics 365.

Learning curve

Power BI is a highly graphical tool that offers a lot of real-time interactivity and a relatively easy learning curve. Elements can be dragged and dropped to create complex, dynamic visualisations.

By contrast, the basic features of SSRS are fairly easy to learn, but more advanced reports must be coded from scratch. The upside is that this can give you deeper insights into the process required.

Reporting

Power BI’s drag-and-drop method allows you to create powerful, highly visual reports in minutes.

Slicers and other selection features allow the user to hide unimportant data, and highlight critical data as per audience requirements. Its reports can be accessed through web services, mobile apps and desktops.

Licensing and updates

Microsoft has released new versions of SSRS every few years, most recently in 2017. Power BI, on the other hand, receives updates every month, driven by a strong user community.

Another benefit of Power BI is cost. Whereas SSRS requires the purchase of an SQL Server license, Power BI is free to use for datasets of up to 1GB in size.

Unlimited data and enhanced features can be unlocked by purchasing Power BI Pro.

This makes it possible for anyone to learn about Power BI and decide if it’s right for them.

Is Power BI the future in Hong Kong?

For Hong Kong IT jobseekers intent on expanding their knowledge of Power BI, these are the top skill sets to focus on:

  • Data visualisation and dashboard design
  • Basic database skills, especially SQL
  • Data preparation, including extract, transform and load (ETL)

As with any BI role, a solid grounding in business, mathematics and/or statistics is also an advantage.

There is no clear pathway to acquiring any of these, so the more experience you can accumulate in any of these areas, the better.

It’s unclear how much longer SSRS will continue to be supported by Microsoft, and Power BI has all but reached the stage where it can do everything that SSRS can do, and more.

Most importantly, Power BI offers a solid guarantee of continued compatibility into a future dominated by web, cloud and mobile technologies.
