Can I save dataset object to an application variable?

Hi My friends,

Can I save dataset object to an application variable? I want all the
customer use this dataset. and diffrent customer create diffrent dataview
object from this dataset, so it don't need to connect to database everytime
.. I know I can use cache object , but cache object can be deleted
automatically if server's memory is low, is this correct?
Would you like to give me more information about how to improve database
webform performace.

Thanks ahead.

Larry
