asp page as mass update utility????

How can I write asp page that allows me to do mass update? I need to develop
web based utility that allows me to update couple of table in mass. For
example I got customer table and order table. I will have Customer as hiarchy
and orader underneath customer. In order secstion I can have multiple order
for one customer and I want to update about 5 fileds from order table as
editable grid, drop down and other stuff. I can also choose more than one
customer as well. How can I do it in ASP? I am new to ASP. Any suggestion
would be thank ful.
