1. UniData，UniVerse：
UniData UniVerse是具有SQL映射层和元数据库功能的多值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应用程序平台的组件。它的优点是速度快，具有用于开发企业应用程序的灵活数据服务器。基于UniVerse的应用程序可最大化可用资源的处理吞吐量，动态分配可用资源。
2.减轻：
Weaviate是基于GraphQL的开源智能图，具有以下核心功能：语义搜索，自动分类和知识表示。主数据库模型是搜索引擎，辅助数据库模型是Graph DBMS。它允许我们的数据基于GraphQL查询语言以大图形格式表示。它是一种基于称为Contextionary的图嵌入机制的搜索图。 UniData，UniVerse和Weaviate之间的区别：
