The model for business intelligence is rapidly changing from hub and spoke to that of a data supply chain, as I pointed out in “Why Building A Distributed Data Supply Chain Is More Important Than Big Data”. More data, more apps, more forms of analytics will all put stress on the centralized model of the enterprise data warehouse and gradually create many different nodes for storing and processing data, all of which communicate with each other.
But all data supply chains will not be equal. There will be huge differentiation created in how these supply chains are constructed. It will take time and experimentation to figure out what works and what does not, but in my view, the ability to create and preserve context for data will be the key requirement.
