How to design schema for NoSQL data models?
The same types of standard data modeling tools are not available for NoSQL data modeling. 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. Another important design driver is the types of data access that need to be supported.
How are NoSQL databases different from relational databases?
NoSQL databases are designed to break away from the rows and columns of the relational database model. But it’s a common mistake to think that NoSQL databases don’t have any sort of data model.
Which is an important design driver for NoSQL?
Another important design driver is the types of data access that need to be supported. Some use cases require access via a query language and others require access by one or more applications. Because no business or application domain is static, change over time must also be taken into account.
Why do we need a NoSQL schema for MongoDB?
Some use cases require access via a query language and others require access by one or more applications. Because no business or application domain is static, change over time must also be taken into account. When it comes to flexibility, NoSQL database schemas are much less costly to revise.
