What is wrong with the Enterprise Data Warehouse? Quite a lot, it seems. By taking the narrow view that the struggle is that of accommodating and interrogating huge quantities of data, then initiatives such as the Virtual Data Warehouse and Logical Data Warehouse could make sense.

Was the marketing hook 'The Internet of Things' conjured up before the technical definition? Are we being persuaded to spend money on fending off yet another fantasy tsunami of data?

12
The options that you need to select when setting up an Azure Storage service account allow you to specify the durability and high-availability of your data, but they don't provide for data recovery to a point-in-time.

IT in general prefers the fuzzier idea of the trashcan, where the deleted compromising documents can blow around a digital landfill site for years.

Rob Sheldon investigates, and finds the cloud a worryingly public place.… Read more
