Existing approaches to data warehousing are increasingly unfit for purpose. The creation of ever-larger warehouses or data marts counts against any meaningful analysis being carried out, and the financial performance of organisations will suffer as they struggle to compete in markets where others have adopted a more modern approach. Data warehouses have to be brought up to date: a different approach is required in how multiple relational and non-relational data sources are dealt with so that the amount of data needing to be analysed and reported against in the warehouse is better controlled and managed. However, the technologies chosen must also be easy for IT staff to implement and manage - the complexities of the underlying technologies must be hidden to provide a system that is easy for all to use.
