Business experts: Some of them set the problem  objective and some provide the decision model that which is based on domain knowledge. The decision model  indicates the data to be collected, the processes from which the data will be collected and the period for which data needs to be collected.

Information technology experts: They design the database which is likely to be filled during trasaction processing, and they also manage the database

Data analysis experts: They understand data mining, statistical and OR techniques.
