The Digital era has brought an impressive number of brand new experts and scientists over the years. A Business Intelligence Specialist and a Business Intelligence Developer are among them. But before we dive into the details of these two positions, let’s answer the significant question: what is Business Intelligence?

“Business intelligence is the process by which enterprises use strategies and technologies for analyzing current and historical data, with the objective of improving strategic decision-making and providing a competitive advantage.”

Some specialists say that BI brings order into information chaos. BI systems combine different techniques to make it possible. These are, for example:

  • Data mining (using databases, statistics, and machine learning to discover trends, similarities and relationships)
  • Querying (using a request for particular information from the database)
  • Data preparation (using combining and structuring to prepare data for analysis)
  • Reporting (sharing data analysis with decision-makers to help them make conclusions and decisions)
  • Benchmarking (comparing business processes and performance metrics to historical data of the industry’s best practices)
  • Descriptive analytics (using the interpretation of historical data to make comparisons and see changes in detail)
  • Statistical analysis (using results from descriptive analytics and adding statistics to discover trends)
  • Data visualisation (using visual representations like charts or graphs for more accessible data analysis)
  • Augmented analytics (using machine learning and natural language generation to automate insights)

Business intelligence systems use many different tools like Ad hoc analytics, Online analytical processing (OLAP), Mobile, Operational or Real-time BI, Software-as-a-service BI (SaaS BI), Open source BI (OSBI), Collaborative BI, Location intelligence (LI) and many other. Although existing tools are developing, new solutions continue to arise, exploring new areas like Cloud solutions. In 2018, Cloud BI adoption skyrocketed to 49%, almost doubling adoption levels of 2016 (25% of enterprise users). The global BI market size will reach 27870M USD by 2026 (from 18720M USD in 2019).
