Data Intensive Web Service

Question

Hi , I am developing a web service for a customer hosting an online job application form. The customer has about 200 input fields ( mostly boolean values of Yes / No questions , string and integers ) which he will be sending to my webservice . Currently I have just written the skeleton code for my web service which is a simple web methodd that accepts 10 i/p fields , validate them and write them to my database My question is what is the best way to accept and send such a large flow of input data? Should I use this same simple function with i/P parameters , or should I go for a structure , collections etc? Keeping in mind that this is an online job application feeding data to my webservice , what is teh best approach one must follow when desiging such data intensive yet time critical web services? Thanks Meena .
