Multiple Cart Objects, or multiple store details in database?

I have been using a single cart for all of my clients different events, and we are at a point where i think it would make sense to store the records for each event in its own table. Example, they have an annual convention, their own industry training school, and now 2 certifications as well. If I want to store the data for each in its own table and am not sure what the easiest way to do this would be.

Can I have more than one cart object in a single site? Or do I need to find a way to have 3 separate checkout processes for the same cart object?

Thanks for your help, trying to plan this out and make the change before my orderdetails table has too many fields.

You can have as many carts as you want on a site. You could do separate checkout processes, or you could save a column in your cart to identify the tables to use. You could do it any number of ways it is just a matter of figuring out what database structure and user experience makes the most sense for your business.
