## What it is
MongoDB is a widely used open-source NoSQL document database written in C++, including the mongod server and mongos sharding router. It stores data in flexible JSON-like documents and supports replication, sharding, full-text search, vector search, and a rich aggregation pipeline.

## Use cases
- store application data in a flexible document database
- run a self-hosted NoSQL database with replication and sharding
- build semantic search or AI apps with vector search
- scale horizontally across shards for high-throughput workloads
- query and aggregate semi-structured JSON data

## When to choose
- you need a flexible schema and document-oriented data model
- you want built-in horizontal scaling via sharding and replica sets
- you need integrated full-text or vector search alongside operational data
- you want a mature database with drivers for most languages

## When to avoid
- you need strict multi-row ACID relational transactions and joins
- you cannot accept the SSPL license for a hosted-database-as-a-service offering
- your workload is small and a lightweight embedded database would suffice
- you need heavy relational reporting with SQL

## Facets
- artifact type: application
- maturity: stable
- function: database, search-engine, vector-database, caching
- domain: databases, backend, web-development, developer-tools
- platform: windows, self-hosted, cloud, cpp
- tags: nosql, document-database, sharding, replication, aggregation-pipeline, sspl, mongod, mongos, search, linux, macos, docker
