Questions: The retail store manager of a telecommunications service provider has been manually entering the data record of device returns into the company's device database every time a subscriber swaps their old phone for a new one. A recent internal audit revealed that several device records are missing from the device database. Which aspect of data management should the store employ to avoid this situation? - Collection - Availability - Accuracy - Encryption

The answer is the third one (Accuracy): Accuracy.

Explanation for each option:

1. Collection: This refers to the process of gathering data. While proper data collection is important, the issue described in the question is not about gathering data but about ensuring that the data entered is complete and correct.

2. Availability: This refers to ensuring that data is accessible when needed. While availability is crucial, it does not address the problem of missing records in the database.

3. Accuracy: This refers to ensuring that the data entered into the system is correct and complete. The problem described in the question is that several device records are missing from the database, which indicates an issue with the accuracy of the data entry process. Implementing measures to ensure data accuracy would help avoid this situation.

4. Encryption: This refers to securing data by converting it into a code to prevent unauthorized access. While encryption is important for data security, it does not address the issue of missing records in the database.

Summary: To avoid the situation of missing device records in the database, the store should focus on improving the accuracy of data entry. This could involve implementing automated data entry systems, regular audits, and validation checks to ensure that all records are correctly and completely entered into the database.
