Well, i think that the model should be projected step down - from the black box to the most posible granuarity.
In first aprox. i think that the simple queriers should be black box'es, there also should be some kind of process modeling. (Data base writter,Listener,Archiver,etc...
like internal structure of Oracle Database) What kind of matematic tool i'll use - it still open problem. I think about construct a simple M/M/1 ? What you think about it ? Received on Fri Jan 19 2001 - 09:41:06 CET
