Difference between UniData,UniVerse and Weaviate

1. UniData, UniVerse:
UniData, UniVerse is a multiValue database and application server with SQL mapping layer and meta database capabilities. UniData makes for easier database design, eliminating the constraints of SQL normalization. UniVerse is a component of the MultiValue application platform. Its advantage is that it is fast, has a flexible data server for developing enterprise apps. UniVerse-based applications maximize processing throughput of available resources, dynamically allocate available resources.

2. Weaviate :
Weaviate is an open-source GraphQL-based Smart Graph with the core features: semantic search, automatic classification, and knowledge representation. The primary database model is the Search Engine and the secondary database model is Graph DBMS. It allows our data to represent in a large graph format based on the GraphQL query language. It is a search graph based on a graph embedding mechanism called the Contextionary.
