Hive technology is integration of CVS and big data joining. [CVS- concurrent version system] CVS is the process of saving repeated data together to reduce total space required for the data storage. For example if the table address is repeated in the tables of sales, inventory, purchase etc. The common attributes in the three tables will be saved in single table and the linked with other attributes with pointer. When we take big data join the HIVE technology will connect 50 to 100 attributes together from more than 500 tables.
