Relational databases create more problems when dealing with these trends. This leads to the emergence of a large number of different techniques to address specific aspects of these problems, which can interact with or replace existing RDBMS-also known as hybrid persistence (Polyglot persistence). Database substitutes are not new, they have been in the form of object Databases (OODBMS), hierarchical databases (such as LDAP) for a long time. However, over the past few years, a number of new

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

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

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

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

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

NEO4J Introduction
Neo4j是一个高性能的,NOSQL图形数据库,它将结构化数据存储在网络上而不是表中。它是一个嵌入式的、基于磁盘的、具备完全的事务特性的Java持久化引擎,但是它将结构化数据存储在网络(从数学角度叫做图)上而不是表中。Neo4j也可以被看作是一个高性能的图引擎,该引擎具有成熟数据库的所有特性。程序员工作在一个面向对象的、灵活的网络结构下而不是严格、静态的表中——但是他们可以享受到具备完全的事务特性、企业级的数据库的所有好处。
