The time span and granularity of decision support data are typically much larger and coarser than operational data. However, the main difference between the two types of data is their dimensionality.

In contrast, decision support data is often structured in a multidimensional format, with each record containing data on multiple dimensions or attributes. Usability and sparsity are not necessarily defining characteristics of either type of data.
