Can blockchain data be stored in a relational database? If so what would the schema be? I know blockchain itself is a data structure, but how is the data stored? In JSON files? In a RDBMS? in CSV file? What do you see in the wild? I'm looking to see if I can implement something for a case study in a RDBMS which we are required to make use of.
Is there any example of a schema for a given blockchain with tables I can find? (I started creating my own and I think it's reasonable).
