Microsoft Dataverse was initially called Common Data Service (CDS). This designation still appears in some places, for example in the designation of the corresponding connector (as of April 2021).
Microsoft Dataverse is a flexible database which, by the way, can also save files / documents in which extensive “business logic” can be stored. You can create views and forms. In addition, “model-driven apps” can be generated from Dataverse databases. That might not sound like spectacular in this short list – but in practice it all makes perfect sense. In contrast to SQL Server, for example, Dataverse does not have to be technically administered. It is, so to speak, “just there”
At this point I would like to mention that Microsoft Dataverse is the data store of Dynamics 365. So there are first-class examples of the performance of this data memory.
