These are the sort of workloads experienced by the majority of web applications. This coupled with CouchDB’s HTTP interface make it a natural fit for the web.
In this part, we’ll tour a document-oriented web application—a basic blog implementation. As a lowest common denominator, we’ll be using plain old HTML and JavaScript.

CouchDB’s API is the same, regardless of whether you’re running a small installation or an industrial cluster.
There is no right answer about which application development framework you should use with CouchDB. We’ve seen successful applications in almost every commonly used language and framework. For this example application, we’ll use a two-layer architecture: CouchDB as the data layer and the browser for the user interface. We think this is a viable model for many document-oriented applications, and it makes a great way to teach CouchDB, because we can easily assume that all of you have a browser at hand without having to ensure that you’re familiar with a particular server-side scripting language.
