copying data from crm to sql database using webservices

Question

Hi folks, Please provide an example showing how to copy data on a daily basis into mssql server from crm using webservices(a scenario which uses only c#.net and another scenario that uses only SSIS) both scenarios would also work. If any specific example related to Eloqua API/Salesforce.com crm would be helpful if not then any crm's example would work. Thank you
