neo4j graph database tutorial

Recently, on the basis of NEO4J Java API and RMI, a set of neo4j management tools is designed, which is divided into server side and client side, and communicates with RMI in middle. Basic functions include diagram database basic information Maintenance Management (creation, editing, deletion, statistics, etc.), graph

according to certain rules, usually only a subset of the sub-graphs can be accessed. The NEO4J database provides a declarative cypher language to query the graph, and neo4j generates a traversal scheme to query the graph. You can also specify the traversal scheme directly,

should be excavated further to increase the knowledge coverage of Knowledge Atlas. Common Mining Techniques: Inference: Mining for entity attributes or relationships through a rule engine for discovering unknown implied relationships Entity importance ordering: When querying multiple keywords, search engines will select entities that are more relevant to the query to display. Common PageRank algorithms compute the importance of entities in the knowledge map. Second,

Cypher is a very good language for working with graph databases, and here are some basic features to learn about his basic usage. Let's do a demonstration with our intelligent Motion Picture

be an actor, a director, or an actor and director. In a relational database, we may need to create different tables for actors and directors. In the graphical database, these three types of people are the data in this node set, but the difference is that they are connected to different nodes through different relationships. In other words, in a graphical database
