What is DD4T

Well, It's the high time to think about DD4T. What is DD4T? What makes more easier to the developer and Editor to talk about DD4T.!!  DD4T is a framework that developed by Tridion veterans. The framework makes it easier for Tridion developers to develop, deploy and maintain a project.

The basic building blocks of Tridion  like, schema, components, template etc. are still remain the same as below.

So what changes, if you look at the below diagram, you could see the different between both

So, the whole logic goes to the web server, CMS just plays the role of generating the pages and delivering it to the Broker, no Template logic or HTML in CMS any more. DD4T solves the problem by making sure the pages and content are published to the broker as data, without any HTML rendering.

If we summarize the diagram.

1) The role of editor and visitor are normal, and that is the main aspect of DD4T architecture.
2) Everything is published to the broker database.
3) Tridion templates uses DD4T to generate XML.
4) DD4T generate the html, not the templates
5) Web application has the complete role and logic for generating the html
6) Doesn't needs to be expert in tridion, Just a .NET developer can be done.
7) In simple the release can be managed well.
8) No dependency with templates.
