database - Triplestore 的使用意味着什么

Question

使用三元组意味着我们要使用一个包含 3 个列和 7 个索引的表的数据库？我的意思是使用三重存储总是与该关系模型相关？

Answer 1

来自 http://en.wikipedia.org/wiki/Triplestore :

A triplestore is a purpose-built database for the storage and retrieval of Resource Description Framework (RDF) metadata.

看起来高性能三元组使用的是非关系模型:

Some triplestores have been built as database engines from scratch, while others have been built on top of existing commercial relational database engines (i.e. SQL-based).⁴ Like the early development of OLAP databases, this intermediate approach allowed large and powerful database engines to be constructed for little programming effort in the initial phases of triplestore development. Long-term though it seems likely that native triplestores will have the advantage for performance. A difficulty with implementing triplestores over SQL is that although "triples" may thus be "stored", implementing efficient querying of a graph-based RDF model (i.e. mapping from SPARQL) onto SQL queries is difficult.⁵
