Document database

Meaning in software engineering, with examples

nounCommon term

In software engineering, document database means: A NoSQL database that stores each item as a self-contained document, usually in a JSON-like format, so related data can be kept together without fixed tables.

In Turkish: doküman veritabanı, belge tabanlı veritabanı

How it is used

MongoDB, Couchbase and Firestore are well-known examples. Documents are grouped into collections, and fields can differ from one document to the next. Teams choose them for flexible data, but must think carefully about embedding versus referencing data.

Example sentences

  1. Product pages with very different attributes fit well in a document database.

  2. We moved the event logs to a document database because their structure keeps changing.
