A programmer chooses a database for a new application that needs to store information, including dates, times, names, and amounts. Which of the following database features is this an example of?
D. Variety
Explanation:
The feature being described refers to the ability of a database to store different types of data, such as dates, times, names, and amounts. This characteristic falls under variety, as databases support multiple data types like strings (text), integers (numbers), dates, and timestamps to accommodate different kinds of information.
Why not the other options?
A. Concurrency – This refers to multiple users accessing and modifying the database simultaneously without conflicts.
B. Speed – While performance is important, the focus here is on storing different data types, not query execution speed.
C. Scalability – This relates to how well a database can handle increasing amounts of data or users, but the question focuses on data diversity.
Thus, variety is the best choice, as it describes the database's ability to store multiple data types.
