neo4j visualization

1. introduction Neo4j is a high-performance, non-relational, fully transactional, and robust graph database. When processing complex network data, neo4j has excellent performance [1] and is suitable for social networks, dynamic networks, and other scenarios. It is implemented based on the java language and has two distribution versions. the community version (communityversion) is licensed by GPLv3 in Git 1.

System Requirements: Open JDK 8 must be installedYou can use the following command to view the system Java environment1 grep GCJ1. Download the JDK and installOfficial website: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.htmlThe version downloaded in this example is jdk-8u144-linux-x64.tar.gzUnzip and place in the/usr/local/java/directory, as shown in2. Modify the system environment variables to point the Java environment to the newly installed environment1 vim

With the weakness of relational database in some aspects, to understand the characteristics and performance of the current popular database patterns will undoubtedly provide us with more choices and directions. Neo4j is a kind of graphic database, which has outstanding advantages in traversal and associated query. Cut the crap and get to know the neo4j before you let us try how to use

5000 items are observed according to the test), we recommend that you use the transaction-Type Insert interface (usually the data operation interface of NEO4J), the speed is still acceptable; when the data volume is large, we recommend that you use the dedicated BatchInserters interface, which does not create transactions during insertion. It is estimated that the memory usage is very small. Basically, the memory remains unchanged during operations o

Getting started with Neo4j (2): matching ModesAnnouncement: All data comes from the book "Building Web Applications with Python and Neo4j", just for study not for commerce.Pattern and Pattern matching are the core of Cypher and describe the shape of the data we want to find, create, or update. If you do not understand the pattern and pattern matching, you cannot write effective and efficient queries.I. Dat
