They are single values whose size and type are fix and do not have any special methods. It concerns all data which can be stored in database SQL in a table with rows and columns. Even though we are currently making major progress in processing and thus also in gaining valuable insights from semi-structured and unstructured data, structured data is often considered more valuable. A hierarchy is defined wherein all similar entities form a group, and such groups are organised into the hierarchy of semi structured data examples. The 3 "V"s of big data are Volume, Velocity, and Variety. Semi-Structured Data Semi-structured data includes e-mails, XML and JSON. Medical records: Healthcare generates . 2. 1.
