Security holes exploit software design: security solutions, update software, smurfing + spoofing distributed denial of service, spoofing: hackers intercept a request and change the source address. They are organized around particular subjects such as marketing, hr, sales or production: data in warehouses are integrated from a variety of internal and external sources, data in data warehouses are typically transformed from their original format. Detailed data are often aggregated: data in data warehouses typically are nonvolatile, which means that the data do not change once in the warehouse, data warehouse process, extract: data are pulled from the source systems. Deciding exactly what data to extract is important: transform: data must be changed into a form that is suitable for decision support.
