1.速度数据库:
VelocityDB 是一个 .NET 对象数据库,可以嵌入/分发并扩展到图形数据模型 (VelocityGraph)。该数据库速度快且内存消耗低。 VelocityDB 是一个性能极高、易于使用、可扩展、可嵌入和可分发的对象数据库系统。

2. 伏特数据库:
VoltDB 是分布式内存中 NewSQL RDBMS 和使用无共享架构的符合 ACID 的 RDBMS。该数据库由 Michael Stonebraker、Sam Madden 和 Daniel Abadi 设计。最初,VoltDB 数据库包括集群吞吐量和延迟以及 CPU 和内存使用情况的图表。 VoltDB 基于 H-Store 并随着多核服务器上每 CPU 核数的增加而扩展。 VelocityDB 和 VoltDB 的区别:
