Title: Jane Hartmann: Innovator in Distributed Join Algorithms

Introduction

Jane Hartmann is a prominent inventor based in Frankenthal, Germany. She has made significant contributions to the field of distributed computing, particularly in the area of join algorithms. With a total of 4 patents to her name, Hartmann's work has advanced the efficiency of data processing in distributed systems.

Latest Patents

Hartmann's latest patents include innovative methods for executing complex join operations. One of her notable inventions is the "Virtual Pair Algorithm for Outer Join Resolution." This system and method facilitate semijoin reductions on outer join operations by creating tuple lists based on a query. The process involves a series of semijoin reduction steps, which either switch one tuple list or reduce all tuple lists at a relation. Virtual connector pairs are inserted into the tuple lists, which are then centralized at a common host for assembling join results. The query result is retrieved by projecting to the requested attributes.

Another significant patent is the "Method for Calculating Distributed Joins in Main Memory with Minimal Communication Overhead." This method involves communication between two servers to execute a distributed join query for a set of documents. The first server generates a tuple list from documents matching a precondition part of the query, extracts value identifiers, and sends dictionary keys to the second server. The second server then converts these identifiers and performs a lookup of documents based on the new set of value identifiers.
