MongoDB Basic Information
MongoDB is a popular NoSQL database known for its flexibility, scalability, and ease of use. It stores data in a JSON-like format called BSON (Binary JSON), which allows for dynamic schemas and makes it easy to work with complex data structures.
Key Features of MongoDB
- Document-Oriented Storage: MongoDB stores data in collections of documents, which can have varying structures. This allows for greater flexibility compared to traditional relational databases.
- Scalability: MongoDB supports horizontal scaling through sharding, allowing it to handle large volumes of data and high traffic loads.
- Rich Query Language: MongoDB provides a powerful query language that supports a wide range of operations, including filtering, sorting, and aggregating data.
- Indexing: MongoDB supports various types of indexes to improve query performance, including single-field, compound, geospatial, and text indexes.
- Replication: MongoDB supports replica sets, which provide high availability and data redundancy by maintaining multiple copies of data across different servers.
- Aggregation Framework: MongoDB includes a robust aggregation framework that allows for complex data processing and transformation operations.
- Flexible Schema: MongoDB’s schema-less design allows for easy modifications to the data structure without requiring downtime or complex migrations.
