The data cube generalizes SQL aggregation across multiple dimensions

arxiv.org by arxiv.org via typesanitizer Editor score 6/10

The paper defines the cube operator as a relational generalization of grouping, cross-tabs, roll-ups, and subtotals, and discusses efficient computation. Its model remains useful context for engineers working on analytical query systems.

What

Data cube is an N-dimensional relational aggregation operator that generalizes SQL GROUP BY and reporting constructs.

Method

Each set of attribute values maps to a point in N-dimensional space; aggregating to lower-dimensional spaces produces super-aggregates.

Why it matters

Because cubes are relations, they can be embedded in more complex non-procedural data analysis programs.
