For example, data processing by big data analytics a specific algorithm can take only minutes, while its preliminary cleaning can take weeks. Organizations need to first raise awareness about big data and its benefits among the employees. Afterward, they need to provide training programs and support to help them learn the basic knowledge of big data technologies and how to utilize the big data tools to grasp valuable insights and achieve their work efficiency.
