How long do collection variables import to sccm database automaticly

[yyyyuuuu386]

I want to learn sccm 2007 database and reports this week .

 

just a moment ago , I add a variable in a computer property of collection .

and then I check v_CollectionVariable , vSMS_CollectionVariable and CEP_CollectionVariables , there is no data about my adding variables record in these views or tables .

 

so I want to ask how long do collection variables import to sccm database automaticly . or which views and tables are the collection variables stored in ?

 

thanks in advance!

in testing envrioment , it is very fast to write computer's variables to database .

wish to help others who want to know it
