Hi Piotr,

Allow me to refer to following documentation, where the supported data storage architectures are explained nicely: https://docs.dataminer.services/user-guide/Advanced_Functionality/Databases/Supported_System_Data_Storage_Architectures.html.

Please see also following page on Dojo about the data storage architecture: https://community.dataminer.services/data-storage-architecture/

I hope this info already helps you.
