Performance of Fractal-Tree Databases
Insertion bottlenecks lie at the heart of database and file-system innovations, best practices, and system workarounds. Most databases and file systems are based on B-tree data structures, and suffer from the performance cliffs and unpredictable run times of B-trees. In this talk, we introduce the Fractal Tree data structure and explain how it works and how it provides dramatically improved performance in both theory and in practice. Although...

This paper, the first step to connect relational databases with systems consequence (Kent: "System Consequence" 2009), is concerned with the semantics of relational databases. It aims to to study system consequence in the logical/semantic system of relational databases. The paper, which was inspired by and which extends a recent set of papers on the theory of relational database systems (Spivak: "Functorial Data Migration" 2012), is linked...
