Hundreds of fields to be populated on the basis of various check box selection

Hi,

I have a requirement I have to display 593 fields on the basis of user's checkbox selection. There are 8 checkboxes and multiple checkbox combinations which is not mentioned. I need to consider all possible selection and populate values accordingly. If user selects any 2 or 3 or 7 checkboxes, I need to display the inner join of (respective tables)of  all the selected checkboxes. please suggest me the best possible way that will take least amount of time. Do i need to populated all 593 fields multiple times as per the user selection? please help
