Without a proper data governance process, big data projects can unleash
a lot of trouble, including misleading data and unexpected costs. The role
of data governance in keeping the big data house in order is just starting to
be understood given the relatively recent emergence of the technology and
its allocation to the IT department. Consequently, governance of big data
environments is at an early stage of maturity and there are few widespread
prescriptions for how to do it effectively. One fundamental problem is that
pools of big data are oriented more to data exploration and discovery than they
are to conventional business intelligence reporting and analysis.
