¢º Operational feedback

¡Ø integrate data-driven decisions back into the operational systems.
¡Ø Example : electronic data interchange(EDI) systems
¡æ keep track of inventory and can automatically place orders when inventory reaches certain levels.
¡Ø also valuable wherever a corporation interacts with customers. (a call center)

 

¢º End users and Desktop tools

¡Ø most important component in any DW.
¢¹ analysts who use the DW in a specialized way. (searching for information)
¢¹ application developers
¢¹ business users who act on the information.
¢¹ Analyst

¡Ø want to access as much data as possible to discern patterns.
¡Ø use special-purpose tools.(statistics packages, DM tools)
¡Ø the purpose of the DW is to create value.
¡Ø a DW brings together data in a cleansed, meaningful format.

¢¹ application developer

¡Ø develop stable and robust applications.
¡Ø some specific needs from DW.
¡æ the application they are developing need to be shielded from changes in the structure of the DW.
¡æ the developers need acces to valid field values and to know what the values mean.(metadata)
¡Ø applications are a product for the end users.

¢¹ business users

¡Ø the ultimate devourers of information derived from the corporate DW.
¡Ø needs : the development of application, the architecture of the warehouse.
¡Ø the people who use the computers on their desks and are willing to take advantage of direct access into the DW environment.
¡Ø applications built for specific purposes.
¡Ø examples
¡æ a resource scheduling application(genetic algorithms)
¡æ a sales forecasting application(neural network)
