-CouchDB est un projet de l'ASF (Apache Software Foundation).\\
-Il s'agit d'une base de données avec une interface RestFul - JSON. Comme j'adore tout ce qui exploite pleinement HTTP, je me penche depuis quelques temps sur couchDB, notamment pour la participation à la création d'un frontEnd PHP pour Zend Framework : Zend_Couch (nom temporaire)
-What CouchDB is:
-    * A document database server, accessible via a RESTful JSON API.
-    * Ad-hoc and schema-free with a flat address space.
-    * Distributed, featuring robust, incremental replication with bi-directional conflict detection and management.
-    * Query-able and index-able, featuring a table oriented reporting engine that uses Javascript as a query language.
-What it is Not:
-    * A relational database.
-    * A replacement for relational databases.
-    * An object-oriented database. Or more specifically, meant to function as a seamless persistence layer for an OO programming language.

+GUN is an ecosystem of tools that let you build community run and encrypted applications - like an Open Source Firebase or a Decentralized Dropbox.
+GUN is a small, easy, and fast protocol for syncing data. Because GUN is small, it can be added to your app to improve a single feature. But because GUN is easy, it can also replace hundreds or thousands of lines of code, networking calls, storage boilerplate, pub/sub routing, cache invalidation, and more. The power of GUN is that it abstracts this complexity into a unified simple API that is very different than traditional systems, with the aim of making it easy to build cool apps quickly.
