Document-based NoSQL databases are designed to handle unstructured or semi-structured data, such as JSON or XML, and provide flexible data models that allow for dynamic changes in the structure of data. The primary features of document-based NoSQL databases are:
1. Horizontal Scalability
2. High Performance
3. Indexing
4. Automatic Caching
5. ACID Transactions
6. Geospatial Indexing
7. Cloud-Based Deployment
8. Strong Consistency
9. Low Latency
10. Schema Migration

27-Apr-2023Document-based NoSQL databases store and manage data in the form of semi-structured documents, typically in JSON or BSON format. Each of these documents represents a single entity and contains all the information related to that entity.
Document-based NoSQL databases have a schema-less design, i.e., they do not require a fixed schema for the data that is stored. This allows for more flexibility in the data model, as the fields can be added or removed from documents as needed.
Such databases have powerful querying and indexing capabilities, improving the efficiency of search operations. They also tend to be horizontally scalable, meaning that they can be scaled across multiple servers to handle large amounts of data and traffic.

26-Apr-2023Document-based NoSQL databases are designed to store and manage unstructured and semi-structured data in the form of documents. The primary features of document-based NoSQL databases are:
1. Schemaless Design: Unlike traditional relational databases that require a predefined schema, document-based NoSQL databases have a flexible schemaless design that allows for easy addition, deletion, and modification of fields without the need for a database schema change. This makes it easier to store and manage unstructured and semi-structured data.
2. JSON-like Documents: Document-based NoSQL databases store data as JSON-like documents that contain key-value pairs. This makes it easy to map data to object-oriented programming languages and web APIs.
3. Scalability: Document-based NoSQL databases are highly scalable and can handle large amounts of data with ease. They can scale horizontally by adding more nodes to a cluster or vertically by adding more resources to a single node.
4. High Performance: Document-based NoSQL databases are designed for high performance and can handle read and write operations at high speed. They achieve this by storing data in memory, utilizing indexes, and optimizing queries.
5. Flexibility: Document-based NoSQL databases are flexible and can handle a variety of data types, including text, images, and binary data. This makes them ideal for use cases such as content management systems, e-commerce applications, and mobile applications.
6. Replication and Sharding: Document-based NoSQL databases support replication and sharding, which enables high availability and fault tolerance. Replication involves replicating data across multiple nodes to ensure that data is available in case of node failure. Sharding involves distributing data across multiple nodes to ensure that data is evenly distributed and that read and write operations are distributed across multiple nodes for high performance.
Some popular document-based NoSQL databases include MongoDB, Couchbase, and CouchDB.
