Databases & Data Storage
MongoDB
Definition
MongoDB is a source-available cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.
Why It Matters
MongoDB is the most popular document database and a leader in the NoSQL space. Its flexible data model and scalability have made it a popular choice for modern web applications.
Contextual Example
A developer building a new web app might choose MongoDB because its flexible document model allows them to iterate quickly without having to define a rigid schema upfront. They can store complex objects directly in the database.
Common Misunderstandings
- MongoDB stores data in a binary format called BSON, which is a binary representation of JSON.
- It is well-suited for use cases where the data structure is variable or evolves over time.
