Cypher (lus nug) Cypher yog ib qho kev tshaj tawm graph lus nug lus uas tso cai rau kev nthuav qhia thiab muaj txiaj ntsig cov ntaub ntawv nug hauv ib qho khoom daim duab . Cypher feem ntau yog ib qho kev tsim ntawm Andrés Taylor thaum ua haujlwm rau Neo4j, Inc. (yav tas los Neo Technology) hauv 2011.

Tsis tas li ntawd, graph query language yog dab tsi?

Tsis muaj ntxiv koom nrog: Ib qho kev piav qhia ntawm Daim duab database lus nug . Lawv tso cai rau koj khaws cov ntaub ntawv raws li cov chaw (nodes) thiab kev sib raug zoo (ntug), thiab tso cai rau koj mus nug data as a daim duab . Lus nug sau tawm tsam daim duab databases yog ze rau yuav ua li cas cov ntaub ntawv yog qauv dua li lwm yam lus nug.

Kuj Paub, ob hom lus nug yog dab tsi? Database lus nug muaj yam tsawg kawg ob subsets ntawm commands: Data Definition Lus (DDL) thiab kev tswj cov ntaub ntawv Lus (DML).

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog lus nug rau neo4j?
