In which of the following scenarios would a stored procedure be beneficial?

  1. An application running on a remote client needs to be able to convert degrees Celsius to degrees Fahrenheit and vice versa

  2. An application running on a remote client needs to collect three input values, perform a calculation using the values provided, and store the input data, along with the results of the calculation in two different base tables

  3. An application running on a remote client needs to track every modification made to a table that contains sensitive data

  4. An application running on a remote client needs to ensure that every new employee that joins the company is assigned a unique, sequential employee number


Correct Option: B

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) An application running on a remote client needs to be able to convert degrees Celsius to degrees Fahrenheit and vice versa - In this scenario, a stored procedure may not be necessary. Converting degrees Celsius to degrees Fahrenheit and vice versa can be easily achieved using a simple mathematical calculation and does not require the use of a stored procedure.

Option B) An application running on a remote client needs to collect three input values, perform a calculation using the values provided, and store the input data, along with the results of the calculation in two different base tables - In this scenario, a stored procedure can be beneficial. By creating a stored procedure, you can encapsulate the logic for collecting input values, performing the calculation, and storing the data in two different tables. This can simplify the code on the client-side and provide a centralized and consistent method for performing the calculation and storing the data.

Option C) An application running on a remote client needs to track every modification made to a table that contains sensitive data - In this scenario, a stored procedure can be beneficial. By creating a stored procedure, you can define triggers or audit mechanisms within the procedure to track every modification made to the sensitive table. This can help ensure that any modifications are properly logged and audited.

Option D) An application running on a remote client needs to ensure that every new employee that joins the company is assigned a unique, sequential employee number - In this scenario, a stored procedure may not be necessary. Assigning unique, sequential employee numbers can be achieved through the use of auto-incrementing columns or identity columns in the database table. These mechanisms can automatically generate a unique employee number for each new record without the need for a stored procedure.

The correct answer is B. This option is correct because a stored procedure can simplify the code on the client-side and provide a centralized and consistent method for performing the calculation and storing the data in two different tables.
