OrientDB基于Java的文档数据库
OrientDB是兼具文挡数据库的灵活性和图形数据库管理链接能力的可深层次扩展的文档-图形数据库管理系统(NoSQL数据库)。可选无模式、全模式或混合模式下。支持许多高级特性,诸如ACID事务、快速索引,原生和SQL查询功能。可以JSON格式导入、导出文档。若不执行昂贵的JOIN操作的话,如同关系数据库可在几毫秒内可检索数以百记的链接文档图。
OrientDB 2.2.15 发布了,
值得关注的增强:
The Schema panel has been improved: now there are two main class categories: “User” Class and “System” Class. The “User” Class now has additional separation between “Vertex“, “Edge” and “Generic” Classes.
New fields to create Vertex, Edge and Generic Classes, along with their buttons, have been added in the Schema panel. It is now possible to specify the number of clusters during class creation – Issue #431 (https://github.com/orientechnologies/orientdb-studio/issues/431).
