For example, content management systems use a database in order to separate the content from page layout. In this case, the data is managed on the server side. Regarding the particular situation of AJAX applications, the data management could be a challenging problem.

It has the next functioning principle: it makes a data layer inside your Web 2.0 or AJAX application. Practically, Taffy DB Javascript database can be included in any type of web application that require the data management on the client side.
Taffy DB provides compatibility with all major AJAX frameworks like Dojo, Prototype, JQuery and so on.
