Looking for a good online payment processing service

[Chrisman886]

I'm going to be selling a service online and I need a third party payment processor to help me with the money part. The development is no problem, but I would like the payment processor to be able to interface with a database (SQL or Oracle preferred). I've never used an online payment processor so I don't know if this is standard or not. Can anyone recommend any payment processing service that may fit my needs as close a possible? Sorry if I'm being too vague but I'm not even sure about the information I need to provide for one to narrow down a decision. Any information would be appreciated.
