Big Data: Data Cleansing and Data Training Remain Big Challenges
The universe of 4.4 zetabytes of data in size, according to a 2014 IDC estimate. But who’s managing that data and how? Forrester says now that the 4.4 zettabytes of data are currently being managed and will grow to 44 zettabytes. Will humans ever be able to effectively manage data of that big?
Data management as a whole is not currently in the best of health. A Forrester report found that despite increased spending by businesses to create big data platforms, considerably more work needs to be done to be able to productively use those platforms. Two big issues for big data are the difficulty of preparing and cleaning data to be processed and the challenge of having the right tools and skills to be able to properly interpret and analyze the data.
The results of the Forrester survey, reported by TechRepublic, found that:
- 67 percent of businesses can’t access their big data
- 59 percent of businesses aren’t able to integrate with big data
- 56 percent of businesses say the update process for their big data is slow
Michele Goetz, principal analyst for Forrester, said that “there is a need to introduce intelligence into the process of interpreting all of this data so the consumers of this data can be empowered to use it through self-service data access.”
Great post, thanks for sharing. Because of the rising importance of data-driven decision making, having a strong data governance team is an important part of the equation, and will be one of the key factors in changing the future of business. There is so much great work being done with data cleansing tools in various industries such as financial services and health care. It will be interesting to see the impact of these changes down the road.
