1. UniData，UniVerse：
它是一个具有 SQL 映射层和元数据库功能的 MultiValue 数据库和应用程序服务器。 UniData 简化了数据库设计，消除了 SQL 规范化的约束。 UniVerse 是 MultiValue 应用平台的一个组件，它的优势是用于开发企业应用程序的快速、灵活的数据服务器。基于 UniVerse 的应用程序最大化可用资源的处理吞吐量，动态分配可用资源。
2. 伏特数据库：
它是分布式内存中 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
