Not all data used for analysis is internal data (data that is created and maintained by your own company), so it needs to be obtained from somewhere other than your company's centralized database. If data is publicly available, then it can be downloaded directly from the internet. If the data is not provided in an easily digestible structured format, it will require you to transform the data before you work with it.
