Apache CouchDB uses a multitude of formats and protocols to store, process, and transfer data. JSON is used to store data, JavaScript as a query language, while HTTP is used for API. A clustered database allows users to run a single logical database server on a variety of servers or VMs as well. CouchDB uses views as the main tool to run queries and create reports from stored files. Views allow users to filter documents by relevance to ensure availability of relevant data regarding database process. This information can then be mapped and extracted according to user preference.
