A dimension table typically has two types of columns, primary keys to fact tables and textual\descriptive data.
Example: Time, Customer

Types of Dimensions:

  •     Slowly Changing Dimensions
  •     Rapidly Changing Dimensions
  •     Junk Dimensions
  •     Inferred Dimensions
  •     Conformed Dimensions
  •     Degenerate Dimensions
  •     Role Playing Dimensions
