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.
Why are NoSQL databases used in 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. They are typically developing applications for massive, horizontally distributed environments.
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.
What’s the difference between NoSQL and key value databases?
Instead, NoSQL databases have a data model that reflects their particular category. Document databases can store a great deal of information in a single document and can nest documents. Key-value stores have a simple data model, just as their name implies.
What are the different types of NoSQL databases?
NoSQL databases fall into four main categories or types. One thing they have in common is that they do not use the rigid tabular row-and-column data model that traditional relational databases (sometimes called SQL databases) use. Instead, NoSQL databases have a data model that reflects their particular category.
Are there any implicit relationships in NoSQL table schema?
There are relationships in my data, but they are mostly what would be N:N in a relational db; there are very few normal 1:N relationships. So in this case, I’m trying to create implicit relationships that will allow me to browse from both ends of the relationship.
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.
