Types of Data

Data is primarily classified into three types :-

1.) Structured Data
2.) Unstructured Data
3.) Semi Structured Data

Structured Data :-  It includes those data which fits perfectly with traditional RDBMS concept.
                                 The data is perfectly carved into rows and columns.
                                 The data can easily fit into the tabular format.
Example :- mysql database

Unstructured Data :- These kind of data do not have a fixed format or structure.
                                     It cannot be stored in traditional rows and column format.
                                     It cannot support any particular schema.
                                     We can put into tabular format.
Example :- Video streaming data,pdf,whatsapp messages etc.

Semi-Structured Data :-It is in between structured and unstructured one.
                                         It has some tags and schema associated with it.
