Hi Nethra You are absolutely right but it not just contained the connecting classes but also the methods for getting the results in desired format. Look at the recommended article section in the right. Thanks.

Hi what amit said is right... Advantages: A change from one DBMS to other will only involve a change to the part in the data access layer. A change in the Use Interface (from desktop to the web will need only some changes in the components of the presentation layer. The benefit of writing the presentation and business layered architecture in different languages is that it is an advantage of the presentation and business layers is that it is feasible to use different developer teams to work on each. It means that only PHP skills are required for data access layer and business layer and HTML CSS and XLS skills for presentation layers. It is easier to find a developer with skills in one of these rather having a kind of developer having all of the skills. Another main advantage of using XML/XLS in the presentation layer is that it the output can be changed from HTML to WML or PDF or any other format using a different XLS style sheet. XLS files can be used to change XML documents into a number of formats and not only HTML. It has better wait balancing system because the entire work load is divided. Security polices can be imposed without effecting the clients. Source: Wifinotes Refer this link for better understanding... Link i hope it help you....
