Excerpt from The Use of Redundancy to Improve Performance: In an Inverted Hierarchical Data Structure
This paper suggests two techniques for reducing the costs of operating certain database applications that use a hierarchical structure with inversion on low-level fields. These techniques are:
1) introducing "family redundancy," i.e., introducing redundant information into a record that was obtained directly, or through a summarization process, from its "parent," "child," or "sibling records," without altering the structure of the hierarchy, or eliminating fields from any records.
2) incorporating one record level into another.
The paper contains formulas which make explicit the costs and savings associated with each technique. A case study will be presented in which the formulas are used to predict possible savings. The observed performance improvements, following the implementation of these techniques, are reported. These improvements corresponded to those predicted by the formulas.
The case study chosen is a birth defects diagnostic assist system. For this system, these techniques reduced the average costs by approximately eighty percent.

Paperback. Condición: New. Print on Demand. This book delves into the use of redundancy as a technique to improve performance in hierarchical data structures. Particularly, the author surveys two such techniques: family redundancy and collapsing of levels. Family redundancy involves the introduction of redundant information into records obtained directly or through a summarization process, without altering the hierarchy's structure or eliminating fields from any records. This data can originate from parent, child, or sibling records. Collapsing of levels, on the other hand, eliminates levels of the hierarchy and duplicates the information they contained in their children. The author provides formulas to help quantify the savings potential of each technique. A case study of a birth defects diagnostic assist system is presented, in which the formulas are used to predict possible savings. The results of implementing these techniques corresponded to those predicted by the formulas, yielding an improvement in average costs by approximately 80%. This book offers valuable insights for database designers and practitioners seeking to optimize the performance of hierarchical data structures. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781332286133_0
