 # Couch Rules: Using CouchDB as a Rules Engine
 
 This is a prototype effort to evaluate the suitability of using [CouchDB](http://couchdb.apache.org/) as the foundation for a rules engine using the built in [document validation features](http://docs.couchdb.org/en/stable/ddocs/ddocs.html#validate-document-update-functions).
 
 ## CouchDB overview
 
-CouchDB is a document-oriented database that stores documents in JSON format and supports [map/reduce](http://docs.couchdb.org/en/2.2.0/ddocs/ddocs.html#view-functions) for querying documents. CouchDB exposes a number of [REST endpoints](https://docs.couchdb.org/en/latest/intro/api.html) for interacting and managing single instances or clusters. In addition, CouchDB supports a special type of document called a [design document](http://docs.couchdb.org/en/2.2.0/ddocs/index.html) that are used to query, display, aggregate and validate updates to data in a CouchDB database.

 When creating or updating a document in a CouchDB database, validation functions are used to "prevent invalid or unauthorized document update requests from being stored."
