You should familiarize yourself with the Concept of Multiversum.
"...Multiversum allows, instead of the existing blockchain simple data model, the creation of a Relational Crypto Database (an advanced and organized data storage solution) which can handle not just a single data-type, but a series of data grouped in graphs of complex data structures related one another. Relations are now first class citizens of the blockchain and are assured by cryptographic methods...."(White Paper)
I haven't understood yet, but the point is, and you can appreciate it.
