What is Business Intelligence?

Business intelligence is used for transforming raw data into meaningful information for analysis through techniques and tools such as MSS, Data Warehousing, OLAP, Data Mining, either individually or in the combination.

How does it work?

  •  Once raw data is gathered, data engineers/analysts or BI developers use  ETL (Extract Transform Load) tool to manipulate, transform, and classify the data in a structured database
  • The structured databases are so-called data warehouses or data marts, where business owners and decision makers can access business data and use them to solve their business problems.
  •  BI developers/analysts can use the data visualization tools (eg. Power BI) to summarize the results on visual dashboards, making such information accessible to various stakeholders. It helps users analyze past performances and adapt future strategy in light of a specific goal. Such as: what does the data say about my latest sales performances, and how can I improve them? Is the data revealing increased ROI from my advertising investments? etc.
