Embodiment Construction

[0031]The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0032] The present invention provides a Redis-based RDF distributed storage method,

[0033] S1: Provide a Redis-based RDF data distributed storage system, such as figure 1 As shown, the storage system includes: a management node (Manage Node) and a processing node (Process Node) and a storage node (Storage Node) that match the management node (Manage Node); wherein, the management node (Manage Node ) provides an external interface, is responsible for receiving and parsing external RDF data, and divides the RDF data according to the class to which the subject in the triplet belongs, and stores each divided class in the corresponding storage node (Storage Node), At the same time, the management node (Manage Node) provides an external query interface, and external systems can query data through the query interface of the management node (Ma...

Abstract

The invention relates to an RDF (radial distribution function) distributed type storage and querying method based on Redis. The RDF distributed type storage method is characterized in that the RDF distributed type storage method of an RDF distributed type storage system which utilizes Type-P data distributing and is based on the Redis is adopted; by judging the complexity of a to-be-queried sentence, different querying methods are selected, so as to quickly and effectively query. The RDF distributed type storage and querying method based on the Redis has the advantages that the distributed type storage system and the optimized querying method are combined, so the querying range is effectively reduced, and the querying efficiency is improved; the working efficiency is high under the conditions of multiple querying tuple modes and complicated semantics, so the storage and querying requirements of a large amount of RDF data are met.

Description

technical field [0001] The invention relates to the technical field of RDF data storage and query, in particular to a Redis-based RDF distributed storage and query method. Background technique [0002] At present, academia has developed some mature RDF (Resource Description Framework) management systems, such as Jena, Sesame, and RDF-3X. Most of these systems use traditional centralized relational databases to store RDF data, and store data according to a certain The organization method is stored in a relational database, and a mature relational or object-relational database is used for background storage, and SPARQL queries are converted into SQL query statements for query. [0003] With the rapid growth of RDF data, the traditional RDF storage management system based on relational database has been unable to adapt to the explosive growth of massive RDF data, more and more researchers began to use the massive data storage and parallel computing of distributed systems Abili...
