1.下载以及安装

http://orientdb.com/docs/3.0.x/fiveminute/java.html

https://orientdb.com/download

cd orientdb-3.0.0
cd bin

1.1 启动服务

sh server.sh

1.2 访问图形化界面

http://localhost:2480/studio/index.html

• Browse 可以查看user，命令： SELECT * FROM OUser
• SCHEMA 查看节点Vertex classes以及边Edge classes等信息
• SECURYITY 管理账户
• GRAPH 支持可视化，创建节点和边，例如输入命令：select from V; 可依可视化
• FUNCTIONS 可以定义函数来扩充sql
• DB 属性以及数据库的导入导出，支持其他数据库格式的导入
• 详情见Introduction to OrientDB Studio，http://orientdb.com/docs/3.0.x/studio/

1.3 创建maven项目

    <dependencies>
        <dependency>
            <groupId>com.orientechnologies</groupId>
            <artifactId>orientdb-client</artifactId>
            <version>3.0.0</version>
        </dependency>
    </dependencies>

1.4 java链接db并创建基本表
