Currently, the neo4j documentation is limited to official documents. This article will sort out the main official documents of neo4j for reference and the content will be updated continuously! Start Features Acid transactions High Availability Scalable to hundreds of millions of nodes and relationships High-speed Traversal Deployment mode Single Instance Mult

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

Label:, Figure database Neo4j Introduction:Http://www.neo4j.org/learn/neo4jNEO4J is an open source map data, very easy to use, lightweight and flexible, embedded, powerful, and related information is complete.According to the official website of neo4j, the database can support billions of nodes:Massively scalable, up to several billion nodes/relationships/propertiesand support distributed deployment, Master

category, and this node has a property name with a property value of Andres CREATE (n:Person {name : 'Andres'}); Insert Edges. Insert a forward edge of A to B, and the category of the Edge is follow MATCH (a:Person),(b:Person) WHERE a.name = 'Node A' AND b.name = 'Node B' CREATE (a)-[r:Follow]->(b); Update the node. Update the node for a person category and set the new name. MATCH (n:Person { na

neo4j Introduction Graph database Requirements  can be clearly intuitive way to store the graph data, rather than distort the change for other alternative way  can simply map operations, such as search, traversal, etc. The basic idea of the graph database (graph) is composed of nodes (node, vertex) and relation (relationship, edge) to record data on nodes (properties of nodes, property)  nodes are organized into graphs by the relationship, and the

Graphical operator interface settings. 2.2 Cypher Basic Statement Cypher is the database language of neo4j, get started words at least need to know and delete to change. Inserts a node. Inserts a node for the person category, and this node has a property name with a property value of Andres CREATE (N:person {name: ' Andres '});Insert Edges. Insert a forward edge of A to B, and the category of th

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

of the execution plan: dbms.index_sampling.background_enabled: Whether the index information is counted in the background, because the execution plan of the Cypher query is based on the statistical information generated, Timely updating of indexed statistics is important for generating performance-optimized execution plans; dbms.index_sampling.update_percentage: How much of the data in the index is updated before updating the index's statistics; cypher.statistics_divergence_thr

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

implemented based on the java language and has two distribution versions. the community version is open-source on Github with the license of GPLv3. the Source Code address is High Availability and is supported throughout the day. The development of Neo4j is very active and involves many projects, including rest api binding (implementation list of various languages) and spatial database support (source code address. Due to frequent updates to the

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
