  • Defining the structure
  • Mapping the data
  • Extracting the data from the source system
  • Performing transformations to convert the raw data into a cleansed and validated format.

The first 3 steps are also referred as data integration.

The data transformation process for BI analysis includes:

  1. Extraction and loading
  2. Exploration
  3. Transformation
  4. Testing
  5. Documentation
  6. Deployment

This transformation is facilitated by tools that prepare raw data for use. Techniques such as data mining, data modeling, data analytics, data visualization, and data storytelling may be employed to analyze and present the data, converting it into actionable and significant information.
