Types of Dimensions in SSAS

In SQL Server Analysis Services (SSAS), there are several types of dimensions that are commonly used:

  • Regular Dimensions: These are the primary dimensions that hold the main attributes of the data.
  • Degenerate Dimensions: These dimensions do not have their own dimension table and their attributes are stored in fact tables.
  • Role-Playing Dimensions: These dimensions are used multiple times in a cube with different meanings or perspectives.
  • Junk Dimensions: These dimensions are used to group small or low-cardinality attributes and reduce the overall complexity of the data model.

Understanding the different types of dimensions in SSAS is crucial for designing efficient and effective multidimensional models.
