Web Service Help



We have Oracle database. I want to connect to that Oracle database, retrieve the table data and insert it in the object of Salesforce Application. I came to know that we need to use web service in Salesforce for this requirement.


Can someone please explain the detail steps for the above requirement  please...

I explored in but instead of getting knowledge, I rather confused bcoz I am relatively new to Salesforce...


If anyone can explain me the step by step procedure that would be of great help.


Many thanks in advance...


Hi Priyanka.. 


You need to write a global class with webservice method and generate a WSDL and that WSDL needs to be consumed by ORACLE. For login method use Enterprise WSDL and call the Login method of Enterprise WSDL .

So u need to consume 2 WSDLs at ORACLE. 

1. Enterprise WSDL for Login Method.

2.The WSDL generated from the global class for actual operation.
