Since this is an emerging technology, solutions for NoSQL data modeling are still being developed. Once you know your patterns, you can design your database to handle these questions specifically. This is done via a partitioning model, and requires that the data modelling is built with this in mind. When that occurs we can create and save the new schema to the database with a schema_version field.

NoSQL databases allow you to implement DDD and Repository pattern properly. This aspect of NoSQL is well-studied both in practice and theory because specific non-functional properties are often the main justification for NoSQL usage and fundamental results on distributed systems like the CAP theorem apply well to NoSQL systems. How do you design for relational data in a non-relational database, i.e. Soft cover. We only store the data that we need to query, so our database doesn’t get too bloated. However, NoSQL data management currently lacks mature methods and tools to manage NoSQL … This requires careful planning to … As more enterprises utilize NoSQL database features, the design will mature with the following benefits: Reusable data model design patterns for more efficient application development.
