Types of data:
Data is mainly divided into; structured and unstructured form of data. Structured
data is that data that is generated typically from firms processes and transaction
systems. For example inventory management system, customer management
system. This data well organised, and easily processed through the traditional
database. Unstructured data on the other hand, originate from a wide variety of
sources. For instance, social media, and can be in the form of text, video, or
images, or audio. Hence, unstructured data represent by far data that lacks rigor
structure of a firm and results to need for more complex system to help in
processing and interpreting the data (Beath, Becerra-Fernandez, Ross, and Short,
2012; Gandomi and Haider 2015).
Bigdata is characterised by its volume, velocity and its variety. Volume wise, the
size of the data available now is in grand scale, which makes it more difficult to
be evaluated using the tradition tools. So also, considering the pace at which both
the economy and the technology is changing, high velocity is needed for efficient
processing. Therefore, big data are produced and processed continually, rather
than on a one-off basis (Kitchin, and McArdle, 2016). In addition, earlier
researchers (O’Connor, 1912) seems to be focusing more on the wide variety of
data, which according to recent research, it is argued that the concept of variety
has been in organisations for a long time, although been hoarded due to
unavailable of technology to process the data (Gandomi and Haider 2015).
