  • Each field (column from data source) is assigned:
    • Data Type
      • integer
      • string
      • date
    • Role
      • Dimension:
        • Qualitative data e.g. name, date, geographical data.
        • Dimension can be used to categorise/segment the data
          • Discrete [more common] - Blue
            • e.g. Product Name
          • Continuous [less common] - Green
            • e.g. Order Year
      • Measure
        • Quantitate/numeric vales that can be measured
