Hi,

Based on your requirement you can connect any kind of External systems.

The WD provides different Interfaces for accessing any Externals systems.

There is special procedure for every intereface.

first your will learn the WD fundametals then you will get all the details about how to connect external systems.

U can connect to R/3 and CRM and Oracele or Access to webservices and all.

Thanks,

Hi,

You can connect to any backend using webdynpro java.

If you know java .........

connect database using... JDBC/EJB/WebService.

Go through the model concepts in webdynpro while using ejb or webservice.

If your backend is SAP R/3 , then use Adaptive RFC model to connect with it.

Hi,

First you define your backend, it can be simple database or a R/3 or may be something else.

depending upon that go for using RFC or WebServices or simple database connection.
