Just a question

Hi everybody, I've been trying to find a case of study to make some kind of validation over a data stored in other place and delivered by XML in SOAP format, I think that if we can make something like that we could validate credit cards or numbers stored in other place, this tool could be a great DB to make some validations over to many matters in forms, and other services trough the web. I believe that if we can find this case of study, maybe could be a good thing to validate credit cards, ID's, nicks, and other kind of data. I'll appreciate comments and documentation about this.
