Data Model Design

Modeling in NoSQL refers to the process of designing how data will be structured and organized within a NoSQL database. Unlike traditional relational databases, NoSQL databases offer more flexibility in terms of data modeling, allowing for different types of data models to cater to varying use cases and requirements. There are several types of NoSQL data models:

Document-based Model
In a document-based model, data is stored as flexible, JSON-like documents within collections. Each document represents a single record or entity, and documents within the same collection can have different structures. This flexibility enables the storage of heterogeneous data and facilitates the representation of complex relationships between data elements.
