1. Neo4j ：
Neo4j 是最著名的图形数据库管理系统，它也是 Neo4j, Inc. 开发的 NoSQL 数据库系统。它不同于 Mysql 或 MongoDB，因为它具有与其他数据库管理系统相比的特殊功能。 Neo4j 还以图表的形式存储和呈现数据，而不是表格格式或 Jason 格式。在这种情况下，整个数据由节点表示，在那里您可以创建节点之间的关系，这意味着整个数据库集合将看起来像一个图形，这使得 Neo4j 与其他数据库管理系统不同。
2. Redis :
Redis 或 Remote Dictionary Server 是一个应用分布式内存键值数据库的内存数据结构项目，由 Redis 实验室开发，最初于 2009 年 5 月 10 日发布。它也是开源软件下发布的BSD 3 条款许可证。它还为我们提供了内存效率、高可用性、快速运行速度，并提供了一些功能，如复制、集群等。
