What is NoSQL data modeling?
A NoSQL (originally referring to “non-SQL” or “non-relational”) database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. NoSQL databases are increasingly used in big data and real-time web applications.
How do I create a NoSQL database schema?
Schema design for NoSQL usually involves designing Keys, Indexes & Denormalization of attributes, all of which are inter-dependent on the application queries & workflows. The query requirements elicitation should include following specifications at a minimum: Business Data Entities.
