The document provides an introduction to NoSQL, particularly focusing on CouchDB, which stores data in JSON documents and supports replication and accessibility through a REST API. It discusses various features and characteristics of NoSQL databases, including ease of deployment and the absence of a required schema. Additionally, it compares popular NoSQL document stores like MongoDB, CouchDB, Couchbase, and Redis, highlighting their unique attributes and use cases.

7. Relational (SQL) model.

8. NoSQL Model
What? Is that all?

11. NoSQL/CouchDB characteristics
• Just a collection of JSON documents.
• Views are defined using JavaScript (Python possible, not fully qualified).
• A database can contain all types of documents.
• How you decide to “type” your documents is totally up to you.
• No data reformatting/schema changing required.
• REST API. Available to any tool that can do http requests (including your
browser using Javascript/AJAX).
• Libraries available for all major scripting languages.

12. Why couchDB?
• Replication allows deployment where needed. Very simple and easy to deploy
• REST/HTTP is accessible through all HP internal firewalls and can be exposed
to external entities on a case by case basis.
• REST/HTTP is accessible by ALL programming languages including command
line utils like cUrl.
• Fully open source(Apache License).
• Simpler features mean simpler admin tasks.
• Binaries available for Mac and Windows for development purposes and local
data caching.
• MAJOR FEATURE: You can attach ANY document to a couchdb JSON
document. This allows the attachment of things such as serial logs and core
dump files.

13. Popular NoSQL document stores
• MongoDB: Very popular commercial database. Proprietary clients and API.
Support for most programming languages. “Big Data” features.
• CouchDB: Opensource (Apache). REST API. Client libraries available.
Supports replication but no advanced features such as sharding.
• Couchbase: Both opensource community edition and commercial edition. Uses
custom API with supplied client libraries.
• Redis: not really a document store. Key/value store for “Big Data”.
