Optimizing Hierarchical Storage Management For Database System

Caching is a classical but effective way to improve system performance. To improve system performance, servers, such as database servers and storage servers, contain significant amounts of memory that act as a fast cache. Meanwhile, as new storage devices such as flash-based solid state drives (SSDs) are added to storage systems over time, using the memory cache is not the only way to improve s...

a Hierarchical Database Manager

This paper describes a new algorithm2 dealing with databases. This algorithm allow to fully manage a database, but their most natural field of applications is the datawarehouse (OLAP). It lies on a de-normalized representation of the database. The data is stored in thesauruses and radix trees (a hierarchical representation of bitmaps) which have interesting properties.

Performance Evaluation of a Two-Level Hierarchical Parallel Database System

Two typical architectures of parallel database systems are the shared-everything and shared-nothing architectures. Shared-everything architecture provides better performance than the shared-nothing architecture but it is not scalable to large system sizes. On the other hand, shared-nothing architecture provides good system scalability but is sensitive to data skew. Hierarchical architectures ha...

Hierarchical Query Execution in a Parallel Object-Oriented Database System

This article presents a hierarchical query execution strategy for a parallel object-oriented database (OODB) system. The system, named PRACTIC, is based on a concurrent active class management model and is mapped to an abstract hierarchical multiprocessor architecture. The proposed strategy is studied analytically and by simulation on a transputer-based machine, verifying the theoretical result...
