Partly to echo Richard's comment. 

One key thing that remains unclear is quite what you mean by 
"database", as Stata has no such notion. Is this a Stata 
dataset or a bundle of Stata datasets, or is the Stata 
processing a means towards an end of holding the data
in some other form? 

Similarly, I don't know what "term" means here either. 

In broad terms, your specification seems a long way from the code 
you posted. 

Perhaps you should work on the specific suggestions already 
made, as I don't think your problem is yet precise enough 
for anyone to write down code without making further wild
