computer science - Optimal update frequency -


i have dataset on data mining operation performed. want base frequency of performing data mining operation on frequency data updated. there equation give me optimal mining frequency on basis of data update frequency? if not, , wanted derive own, how go it? if wanted include more variables? need pointers reading materials if there available. thank you.

this isn't cs problem though sounds 1 (unless it's homework problem... i'll assume have real world problem solve). assume if "data mining" doing more running queries against live oltp database (such setting cube on separate system). it's going boil down user problem. answer going depend on:

  • the patterns in data capturing (is cyclical i.e. hourly/daily/weekly). updates more frequent once cycle not useful. if it's event based, , events not happening continuously, updating mining system more incoming events useless.
  • can collect data transform data-mining setup without bogging down users or systems writing original data? if not, need when system load low. if analyzing logs, or utilizing automatic replication (i.e. oracle streams) not constrained here.
  • when can folks/processes doing data mining stop , accept new data-set... can't pull rug out under ongoing work , replace data working on.

the answer won't can "derive." come constraints of users (automated or human) @ either end.
