Databases using JSON as storage/transport format

Question

How many database systems there are that use JSON for storage or transport? I know of:

• CouchDB
• MongoDB
• DBSlayer

I remember I saw yet another vendor in a SO user's profile. That systems was using what they called binary JSON, but I can't remember the name of the product.

Lately, it appears that more and more DB projects are looking towards JSON for persistence storage. Some of them are even embracing HTTP as a transport layer.

Solution 1

MongoDb is the one that uses a binary JSON storage format. I don't know if there is another that is document oriented. Most of the others are key value stores and can only retrieve an object based on one key.

Solution 2

Persevere is another DB that is loaded up with JSON:

Primary transport is JSON HTTP/REST

Data is stored as JSON

It has a native JS/JSON client for running directly from the browser.

If you want a schema then it is defined using JSON

This is a non-authoritative list.

• FleetDB
• MongoDB
• OrientDB
• Apache Cassandra
• Redis
• RavenDB

Solution 5

MongoDB does not use JSON but BSON.

RethinkDB is a document oriented database with a JSON data model, which supports sharding and replication
