NoSQL is a type of database designed to handle unstructured and semi-structured data. It offers flexibility and scalability, making it suitable for applications dealing with evolving data models. Unlike relational databases that rely on predefined schemas, NoSQL databases are often schema-less or have flexible schemas. This allows for easier data integration and accommodates a wider variety of data types, such as JSON documents, graphs, and key-value pairs. Its core philosophy is to provide the option for the data model to be flexible.
Key features include:
- Flexible schemas
- Horizontal scalability
- High performance for specific workloads
- Efficient storage for diverse data types
While relational databases excel at structured data and transactions, NoSQL databases are preferred when dealing with:
- Big data
- Rapidly changing data
- Content management
- Internet of Things (IoT)
