That depends on your requirements, about which we know nothing.

Sorry for stupid and incomplete post .
My requirement is like
I have one table(col1,col2,col3) .There are many columns but my where clause doesn't need it . There are about 3 frequent query
against this table .One query is select on col1(primary key) .Second query is order on col2(int type) . third query is order on col3
.col1,col2 are constant whereas there are frequent updation on col2 .
I want a snapshot of database .Instead of taking data from database ,i can take it from cache .

That sounds like a basic enough thing to do that any of those packages should support it.
