various systems, while a Hadoop environment is well suited to deal with structured, semi-structured,
and unstructured data, as well as when a data discovery process is needed.
B. Hadoop environments are mostly ideal for analyzing structured and semi-structured data from a
single system, while traditional data warehousing environment is well suited to deal with
unstructured data, as well as when a data discovery process is needed.
C. Typically, data stored in Hadoop environments is cleaned up before storing in the distributed
file-system.
