Public and Private Data

Broadly, data sources can be of two types:

  • Private data
  • Public data

Private data: As the name suggests, it is private and belongs to an organisation, and there are certain security and privacy concerns attached to it. It is used for the companies’ internal analysis purposes in order to gain business and growth insights. Some examples of such organisational private data are telecom data, retail data, and banking and medical data.

Public data: This is the data that is available for public use and is offered by many sites such as government websites and public agencies for the purpose of research. Accessing this data does not require any special permission or approval, hence the name. Also, there are many programming techniques that are used to fetch public data through code, which you will learn about later in the module.

Let’s listen to Anand to understand more about data sources types.

To summarise, data is of two types, public and private, and each comes with its set of disadvantages. Public data is not always relevant or useful, and private data is not always easily available.

In the next segment, you will learn about the different types of private data sources.
