Business intelligence tools provide valuable resources for decision-making and improving performance. You can choose between proprietary products and open-source software. The latter has a few more advantages besides being free.

The explosive data growth has been overwhelming for many businesses. Companies struggle with information overload, lack of data management expertise, and ever-growing pressure from competitors more adept at plowing through petabytes for market insights.

Yet, with the right approach, the challenges can be easily viewed as opportunities. The ability to harness large amounts of business data can improve a company’s operational efficiency and drive its growth.

What is business intelligence?

The practice of converting data into valuable, market-relevant insights is known as business intelligence (BI).

The term was coined in the nineteenth century, but it has gained a new meaning in the age of big data. Currently, the concept spans a wide range of solutions for sourcing, analyzing, and utilizing massive amounts of information for streamlining business.

In many organizations, BI is an integral part of the decision-making process. According to statistics, 52% of software companies and 50% of finance firms use BI tools for finding new revenue streams.

The global BI market is growing rapidly and is predicted to reach $43.03 billion by 2028 – almost double the value from 2021.

How does business intelligence work?

Business intelligence starts with extracting valuable data from relevant sources. Companies can obtain useful information from customer relationship management platforms (CRM), web analytics tools, supply chain systems, sales, and marketing performance software, call center applications, etc.

Raw data collected from various systems is sorted into data marts, subject-oriented databases making up a larger data warehouse. Then a variety of BI tools are deployed to analyze data, create reports, interactive dashboards, and data visualizations, and, eventually, produce conclusions about patterns, trends, and existing or prospective business opportunities.

An open-source BI tool vs. proprietary software. Which one to choose?

There is a wide gamut of services for BI applications combining both open-source and commercial solutions. The latter usually offer expanded functionality. Proprietary software dedicated to business users provides additional features compared to no-cost offers. It usually comes with a more user-friendly interface, enables easy integration with other applications, and doesn’t require programming skills for customization. Customer support is also a non-negligible asset.

On the other hand, open-source BI software can be a big money saver, allowing users to invest funds elsewhere. Moreover, choosing free solutions provides the opportunity to test different tools before deciding on the specific one. Such is also the case with using free trial periods offered by software vendors – albeit within a limited time.

Other typical key features of open-source tools include:

  • flexibility with customizing source code to fit your needs,
  • lack of licensing requirements which saves you legal liability nightmares
  • self-sufficiency and independence from software industry vendors
  • frequent updates, if the software is backed by a strong community.

If you’re new to the BI industry, commercial business intelligence software might not be the best choice for starters. We suggest you try open-source alternatives and carefully prioritize your needs before deciding on more advanced options.
