Neo4j Graph Database

*Neo4j: Graphs for Everyone

Neo4j is the world’s leading Graph Database. It is a high performance graph store with all the features expected of a mature and robust database, like a friendly query language and ACID transactions. The programmer works with a flexible network structure of nodes and relationships rather than static tables — yet enjoys all the benefits of enterprise-quality database. For many applications, Neo4j offers orders of magnitude performance benefits compared to relational DBs.

*Using Neo4j Neo4j is available both as a standalone server, or an embeddable component. You can download or try online.

*Extending Neo4j We encourage experimentation with Neo4j. You can build extensions to Neo4j, develop library or drivers atop the product, or make contributions directly to the product core. You’ll need to sign a Contributor License Agreement in order for us to accept your patches.

*Dependencies Neo4j is built using Apache Maven version 3.3 and a recent version of supported VM. Bash and Make are also required. Note that maven needs more memory than the standard configuration, this can be achieved with export MAVEN_OPTS="-Xmx512m".

*OS X users need to have Homebrew installed.

->With brew on OS X
->brew install maven
->Please note that we do not support building Debian packages on OS X.

*With apt-get on Ubuntu ->apt install maven openjdk-8-jdk

On top of that, to build Debian packages and Neo4j Desktop: apt install debhelper devscripts dos2unix dpkg make xmlstarlet # You will need a license for install4j, which is only needed for Neo4j Desktop curl -O http://download-keycdn.ej-technologies.com/install4j/install4j_linux_6_1_4.deb dpkg -i install4j_linux_6_1_4.deb

*Building Neo4j

Before you start running the unit and integration tests in the Neo4j Maven project on a Linux-like system, you should ensure your limit on open files is set to a reasonable value. You can test it with ulimit -n. We recommend you have a limit of at least 40K.

->A plain mvn clean install will only build the individual jar files.

->Test execution is, of course, part of the build. For further reading-https://neo4j.com
