DAL, for which of the following reasons are analytical sandboxes the preferred type of data repository rather than those used by the rest of the organization?
Select all that apply.
A) The IT group in a company cannot interfere with the nature of data, security policies, and data transfer protocols that are required and used by the data analytics team.
B) The data analytics team is a high-performing team working on extremely short deadlines and cannot afford to wait for members of other IT teams to set up the databases, data mining procedures, and test data models.
C) The data analytics team needs to collect and analyze high volumes of diverse types of data in order to achieve its goals, whereas IT is inclined to grant access to only the minimum data needed to achieve data analytics’ objectives
D) The IT group in most organizations simply does not have the expertise to provide the data and support the analytics team needs
E) Creating a sandbox for the data analytics project ensures none of the operations need to be done in the live, production version of the organization’s databases, thereby eliminating the risk of unauthorized access or corruption.
