Developing a Single EDW
If you were still in the process of combining and constructing one data warehouse for all your enterprise functions, big data may stomp out those plans for good. In its expectations of disruptive tech trends for 2013, Gartner Research writes that the maturity of strategic big data will move enterprises toward multiple systems content management, data marts, specialized file systems, for example tied together with data services and metadata to make a logical enterprise data warehouse.
Relying on Existing Infrastructure
Many early big data adopters are hitting a wall on one aspect of implementation in particular: belief that present information infrastructure is sufficient. According to a survey of 1,144 business and IT professionals involved in some stage of a big data program, most enterprises should not expect to simply layer on more analytics programs or solutions. On the surface, a combination of adding storage and one or more larger servers can support the growth of an information management foundation. However, it is important to understand that anticipating and architecting the infrastructure is key to delivering the business value of the intended business case, the survey authors wrote.
Mounting Social, Privacy Concerns
One of the lures over big data plans is the promise of finding profits in social media posts and public sources. Rumbling beneath that are quandaries among the legal community and at the government level about business big data plans with personal information including information stored in the cloud. And the IEEE and other industry organizations are taking their own cautionary view on the actual returns from noisy data sets like Facebook posts and tweets.
