As shown here, there are three distinct steps to tackling Power BI. The most important step in any business insight is to establish a strong connection with the data source and include it in the data extraction process.

  • Data Processing– Information handling is the next step in the business insight process. Frequently, the raw data contains unintentionally incorrect data, or several information fields may be blank. To be handled in the information handling step, the BI instrument must interpret the missing characteristics and off-base information.
  • Data Presentation– Examining the information obtained from the source and presenting the experiences using visually appealing diagrams and sophisticated dashboards is the final stage in business knowledge.
  • Data Integration– The most important step in any business insight is to set up a good connection with the information source and coordinate it so that information can be separated for processing.
