How to design Webservices and Backend for the page having multiple checkbox list control?

Hello Everyone,

 I have a page containing atleast 5 CheckBoxList control. Each of the CheckBoxList control has atleast 5 to 10 list items. I need  to update  the backend with all the checkbox values. It requires too many information to be passed to the Database. Can some one suggest the design solution for this? I have webservices and DAL which calls the stored procedure. If some one show the sketch of how the webservice and Stored procedure structure looks it will be helpful.

Cheers,
