This reference section provides information on the MDX expression types supported in InterSystems IRIS Business Intelligence.

Also see “Accessing the Samples Shown in This Book,” in the preface.

  • Numeric Expressions – This section describes how to create and use numeric expressions in InterSystems MDX.
  • String Expressions – This section describes how to create and use string expressions in InterSystems MDX.
  • Logical Expressions – This section describes how to create and use logical expressions in InterSystems MDX.
  • Tuple Expressions – This section describes how to create and use tuple expressions in InterSystems MDX.
  • Member Expressions – This section describes how to create and use member expressions in InterSystems MDX.
  • Level Expressions – This section describes how to create and use level expressions in InterSystems MDX.
  • Hierarchy Expressions – This section describes how to create and use hierarchy expressions in InterSystems MDX.
  • Set Expressions – This section describes how to create and use set expressions in InterSystems MDX.
  • Measure Search Expressions – This section describes how to create and use measure search expressions, which enable you to access rows from the fact table based on the value of a measure for the facts themselves (that is, at the lowest level rather than at an aggregate level). These expressions are an InterSystems extension to MDX.
  • Quality Measure Expressions – This section describes how to create and use quality measure expressions, which provide access to the values of quality measures. These expressions are an InterSystems extension to MDX.
