Description: The mapping schema defines how information is organized and related in a database. This concept is fundamental to understanding the data structure in NoSQL databases, which are designed to handle large volumes of distributed data. In a NoSQL database, the mapping schema is based on a flexible data model, where data is grouped into collections that can contain multiple fields and documents. Each collection has a unique identifier that determines the uniqueness of the documents and is composed of one or more fields. Additionally, the schema allows defining relationships between different collections, facilitating efficient data querying and access. Unlike traditional relational databases, where the schema is rigid and requires strict definitions, NoSQL databases offer flexibility in schema definition, allowing developers to adapt it to the changing needs of applications. This mapping capability is crucial for optimizing query performance and ensuring system scalability, making it a popular choice for applications requiring high availability and real-time performance.
