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 (prop

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 con

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

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 envi

NEO4J Introduction Data storage is generally an integral part of application development. The data that is generated and required in the application run is persisted in a specific format. A common task in application development is to convert between the domain object model of the application itself and the data storage format. If the data storage format is similar to the domain object model, the mapping relationship required for the conversion is mo

Before delving into the graph database, first understand the basic concepts of the attribute map. A property graph is a Vertex that consists of a vertex (edge), a label (lable), a relationship type, and a property. Vertices are also called nodes, and edges are also called relationships (relationship); In graphs, nodes and relationships are the most important entities, all nodes are independent, and nodes are labeled, so nodes with the same label belon
