neo4j jdbc

Label:NEO4J's JDBC connection is actually sending an HTTP request (using the httpclient), for Chinese, when inserting data, JDBC uses UTF-8 encoded post submission, but when the Chinese data is returned, it does not indicate that the data is UTF-8 encoding. Therefore, HttpClient will use the platform to parse the data, if the platform encoding is GBK and other coding, the good case, the platform can be enco

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

https://www.ibm.com/developerworks/cn/java/j-lo-neo4j/NEO4J is a high-performance NoSQL graphics database. 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

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

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,

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!

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
