Beyond Uniformity and Independence : Analysis of R-trees Using the Concept of Fractal Dimension

Summary: Introduce fractal dimension to quantify deviation from uniformity; show many real spatial point sets behave as fractals with non-integer dimensions. Use fractal dimension + cardinality to derive a formula predicting R-tree range-query I/Os for skewed data (error usually <5–10%), enabling analysis and optimizer estimates without uniformity/independence assumptions.
