The first step is to establish business requirements, and work out the specific needs of the people who will use the application. But they still need to think about the data model they will use to organize the data.Ī fundamental property of NoSQL databases is the need to optimize data access, which puts the focus on query patterns and business workflows. This puts an emphasis on figuring out how the scalability and performance of the system will work. They are typically developing applications for massive, horizontally distributed environments. Generally speaking, because NoSQL databases are designed to store data that does not have a fixed structure that is specified prior to developing the physical model, developers focus on the physical data model. When it comes to flexibility, NoSQL database schemas are much less costly to revise. Some use cases require access via a query language and others require access by one or more applications.īecause no business or application domain is static, change over time must also be taken into account.

Another important design driver is the types of data access that need to be supported.
One recommendation is to begin with a business domain model expressed in a form that can be incorporated in an application, such as a JSON document.
The same types of standard data modeling tools are not available for NoSQL data modeling. Various formal tools exist for describing the relationships between the main objects in a business domain, and these formal descriptions can then be used to dictate how the data will be stored. Relational databases have had generations of users and developers to work out standard design methods. A useful description of how the data will be organized is the beginning of a schema. But it’s a common mistake to think that NoSQL databases don’t have any sort of data model. NoSQL databases are designed to break away from the rows and columns of the relational database model.
