HBase Data model has four dimensions whereas RDBMS has two dimensional model ( row , columns)

  • column families specified when the table is created and cannot be changed once the table is created.

  • columns need not be declared when the table is created

  • column familiy can have any number of columns , dont need to specify upfront
