Since most NoSQL databases lack ability for joins in queries, the database schema generally needs to be designed differently.There are three main techniques for handling relational data in a NoSQL database.
For that reason many NoSQL databases are using what is called eventual consistency to provide both availability and partition tolerance guarantees with a maximum level of data consistency.
