1. neo4j IntroductionNeo4j is a Java-implemented, high-performance, NoSQL graphics database. NEO4J uses graph-related concepts to describe the data model, modeled by the relationship of nodes and nodes in the diagram. NEO4J is fully acid-compliant and transactional. NEO4J the domain data with "node space", the node spa

Recently need to use neo4j to do a small test, seemingly a smooth installation but when the server started the error. Finally found the problem is JDK1.7 installation, less modified a symlink. My installation steps are as follows: JDK1.7 was downloaded from Oracle and Java_home variables were modified in ~/.BASHRC. The code is as follows Copy Code Export Java_home=/usr/libexec/java_home-v 1.7 Checked the curren

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.

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

was created, the system needs to know important information such as the number of nodes and connections contained in the current database, index, and index. This information will help Neo4j design an efficient and effective execution plan, so that our query requests can be responded faster. The next section describes the execution plan process in detail, but one of the steps for an effective execution plan is Index Sampling. In fact, Index Sampling i

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
