Hierarchic Database Structures for Implementing Taxonomic Database Systems

这项研究的主要重点是处理分类数据， 它们涉及到分类学等级和生物学 分类。 将开发信息处理模型 对于分类之间的相互作用等重要问题， 在一个共享的， 分布式环境，开发 跨学科分类层次结构和各种查询- 层次分类数据库的处理策略。 这些 信息处理模型将导致一个 设计和实施数据库的概念框架 分类信息 一个原型分类数据库系统将 建立在这些新概念的基础上。 递归 关系结构和递归视图定义的新思想 这种关系将促进执行办法。

The primary focus of this research is to process taxonomic data as they relate to the taxonomic hierarchy and to biological classifications. Information-processing models will be developed for such important issues as interactions between classifications, efficient representation of classifications in a shared and distributed environment, common frameworks for developing the taxonomic hierarchy across disciplines, and various query- processing strategies for hierarchic taxonomic databases. These information-processing models will lead to the development of a conceptual framework for designing and implementing databases for taxonomic information. A prototype taxonomic database system will be built on the foundation of these new concepts. Recursive relation structure and a new idea on defining views for recursive relations will facilitate the implementation approach.
