WD4A - Introduction

This Blog is for ABAP developers who are familiar with the ABAP development workbench and the user interface development methods available and who now want to implement business processes and their user interaction based on the WD4A framework.
This blog will help you better support users and it will help you with problems that can arise during the migration to WD4A framework. This Blog will discuss general concepts for designing and developing web-based systems and specifically details their specifications when the are implemented within the WD4A framework.
If you are experienced in developing web applications based on JSP and BSP or other technologies
you might be surprised at the restrictive handeling of  the WD4A framework when it comes to the manual integration of javascript. This restriction was introduced in order to enable the WD4A applications to support emerging client technologies that don’t use javascript for client-side flow control.

Sound knowledge of object oriented ABAP programming is a must for understating WD4A concepts. A number of technologies like HTTP, HTML, CSS, XML and client side scripting etc are integrated in WD4A applications.
These technologies are encapsulated and details of these are not shown to you when you use the WD4A framework for web application so that you can focus more on the business process and implementing it rather on the intricacies of these web development technologies. That is the magic of WD4A framework.

To clearly understand WD4A framework, one should know the following :

Communication process in HTTP and HTTPs ie the request response cycles.
Programming in a distributed development environment.
Difference between client side and server side scripting
Use of design patterns in programming
