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 应用程序平台的一个组件。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 的应用程序最大化可用资源的处理吞吐量，动态分配可用资源。
2.编织：
Weaviate 是一个开源的基于 GraphQL 的智能图，其核心功能是：语义搜索、自动分类和知识表示。主要数据库模型是搜索引擎，次要数据库模型是图形 DBMS。它允许我们的数据以基于 GraphQL 查询语言的大型图形格式表示。它是基于称为上下文的图嵌入机制的搜索图。 UniData、UniVerse 和 Weaviate 之间的区别：
