Selections of tools in DW/BI

The selection of data warehouse technology – both hardware and software – depends on
many factors, such as:
• the volume of data to be accommodated,
• the speed with which data is needed,
• the history of the organization,
• which level of data is being built,
• how many users there will be,
• what kind of analysis is to be performed,
• the cost of technology, etc.
