Using the data for other php stuff

I'm trying to find a way to use this data for other means.. i.e standard mysql queries.

For example, If I'm collecting data normally into a table then I am able to do something like this
Table:
id - submitted by user id - my order - my side dish
1 - 54 - Hamburger - Fries
2 - 34 - Pizza - Spaghetti
3 - 54 - Soup - Potatoes

Then I could do simple commands like show all entries from user 54..
I have a lot of data I'll be collecting, and need to use it on other pages where it will be showing the data from many entries (not just one entry on a page or post). I also need to be able able to use the data to compare it to other tables. Can this type of thing be done or am I better of hard coding my forms? I've tried to search for hooks and things to do it, with no luck

Thanks!

I am assuming when you say "You don't have to go direct to the database either" you are referring to the Entry Object. But from the documentation I am not really sure how to go about using the code there. How do I specify the form id to get to the entry data?

Hey Chris, here is my code: http://pastie.org/private/b2g5ptyucvo43j5ftq0na

Starting at line 104 is where I am working with Gravity Forms. I think I have done a decent job as it pulls everything that I need.

I also have an AJAX call to a separate PHP file to set the attended? field: http://pastie.org/private/enrfw93yixxtvdlrlub4q

I would love your input. Thanks!
