Title: Allen N Diaz: Innovator in Relational Database Management Systems

Introduction

Allen N Diaz is a notable inventor based in Santa Ana, CA, with a focus on advancements in relational database management systems (RDBMS). He holds 2 patents that showcase his innovative contributions to the field. His work emphasizes the importance of optimizing cost profiles and enhancing multi-threading capabilities within database systems.

Latest Patents

One of Diaz's latest patents is titled "Dynamically learning optimal cost profiles for heterogeneous workloads." This invention involves an RDBMS that accepts a workload comprised of one or more queries against a relational database. The system evolves a default cost profile into multiple cost profiles using fixed or dynamic evolution. Each cost profile captures various cost parameters for the workload and is represented by a multi-dimensional matrix. The RDBMS dynamically determines the optimal cost profile for the workload by employing a random walk scoring algorithm or a biased walk scoring algorithm. This innovative approach allows the RDBMS to select and execute query plans based on the optimal cost profile.

Another significant patent by Diaz is "Multi-threading, multi-tasking architecture for a relational database management system." This invention presents a parallel processing architecture for an RDBMS that supports both process model and thread model operating systems. The RDBMS is designed as a shared-nothing, single database image utilizing Parallel Database Extensions (PDEs). These extensions insulate the RDBMS from operating system specifics and provide techniques for accessing common memory segments.
