neo4j manual

The neo4j being used is the current latest version: 3.1.0, various tread pits. Say how to use the Chinese index in neo4j 3.1.0. Choose the Ikanalyzer to do the word breaker. 1. First refer to the article: https://segmentfault.com/a/1190000005665612 The way of indexing with Ikanalyzer is roughly spoken. But it is not clear, in fact, the background of this article is to use embedded

NEO4J uses graph-related concepts to describe data models, saving data as nodes in diagrams and relationships between nodes. The relationship between data in many applications can be modeled directly using the concept of nodes and relationships in the diagra

understand the relationship is the key to correct use of the graphical database.Note: The node set here is my own translation. In the NEO4J official document, it is called a label. The original is: A label was a named graph construct that was used to group nodes into sets; All nodes labeled with the same label belongs to the same set. I personally feel that the blunt name label is easy to confuse others, so chose the "group nodes into sets" of the fr

Create a Neo4j Cluster Environment Introduction: Neo4j is currently the mainstream graph database. It also provides highly available cluster solutions. This article will try to build a highly available Neo4j environment. 1. What is graph database? Graphic database is a set of data stored in the same row as certain data on the basic elements of vertices, wires, an

Last Review: This article mainly describes the Neo4j Spatial project and space data (vector) storage. This article describes how to integrate Neo4j Spatial with Neo4j Server and GeoServer. Noted: it is feasible to integrate with Geoserver, but geoserver cannot display the layers in the Publishing Database. (System environment: Ubuntu 12.04, Spatial 0.9,

1. Introduction to Neo4j Neo4j is a high-performance, NoSQL graph database implemented in Java. Neo4j uses graph-related concepts to describe the data model, and uses the relationship between nodes in the graph to model. Neo4j is fully compatible with ACID transactions. Neo4j
