A database is an organized collection of which type of related data?
Correct answer: A. Logically
- A. Logically
- B. Physically
- C. Loosely
- D. Badly
Explanation
Here are the options, along with explanations for why each option is correct or incorrect:(A) Logically - This is the correct answer. A database is designed to store data in a logical way, with relationships between different pieces of data. This makes it easier to find, manage, and update the data. For example, a database of customers might include tables for customer information, orders, and products. The tables would be linked together so that you could easily find all of the orders for a particular customer, or all of the customers who have purchased a particular product.(B) Physically - This is incorrect. While data in a database is stored physically on a storage device, the logical organization is more important. The physical structure of the data is not important to users or applications that interact with the database.(C) Loosely - This is incorrect. A database is designed to have a strict structure to minimize data redundancy and inconsistencies. Loosely structured data would be more difficult to manage and query.(D) Badly - This is incorrect. A database is designed to store data in a well-organized way, not badly
