According to Dain C. Hansen, Big Data turns traditional information architecture on its head with such new technologies as Hadoop and NoSQL. Hansen recommends three initial steps in the approach to Big Data:

• Throw out everything you know about data management, data integration tools, and start completely over; and throw out all the business applications that do not run on Big Data
• Then isolate big data IT systems from current, non-big data enterprise IT systems.

Hansen says users will then qualify for the first step of the journey: bridging the two worlds of enterprise data and big data.
