Structured data

-
A benefit is the same data is gathered each time meaning it is easy to store and analyse , data can be processed more efficiently and data can be moved easily
The drawbacks of structured data is that gathered is fixed data may need to be changed to fit a method of collection and it is not flexible so it is limited on how it can be used
Unstructured data
-
It is collected it can be gathered from many different formats , type and it never the same each time .
The benefit of unstructured data is gathered freely as it occurs ( there is no limit to present values ) and more data can be gathered because it can include data that cannot be changed to fit in a table format .
The drawbacks of unstructured data requires more processing before the data can be gathered for analysis , more costly because specialist systems needs to able to analyse more different forms .
Semi structured

-
The benefit of semi-structured data there is not set format allowing variety of different forms the data has some structure to processing is still easy and it has the same benefits as the unstructure and structured
