A company has a web application where users can search for products. The search results are generated by a query that joins multiple tables and applies complex filtering. The company wants to ensure that the query logic is not visible to users and that the database credentials are never exposed. Which approach should the development team take?

Store the query logic in a database view and grant users direct access to the view.

Use a client-side script to call a public API that performs the search.

Implement the search logic in a server-side script that connects to the database and returns only the results.

Embed the SQL query and database credentials in the client-side JavaScript code.

A web developer is building a form that allows users to enter their date of birth. The developer wants to validate the date format on the client side before the form is submitted to the server. Which approach should the developer use to ensure the validation happens without a round trip to the server?

Use a PowerShell script to validate the date before the form is rendered.

Use a SQL CHECK constraint on the database column to validate the date.

Use a server-side script in PHP to validate the date after the form is submitted.

Use JavaScript in the browser to check the date format and display an error message if it is invalid.

A database administrator wants to automate a routine backup by running a series of database commands from a script. Which approach is most appropriate?

Manually typing each command in the database client each time

Writing a client-side JavaScript to run in the browser

Using a command-line script with the database client and scheduling it

Using a GUI tool to run the commands interactively

Which of the following is a key advantage of server-side scripting over client-side scripting for database operations?

It works even when the user is offline

It reduces server load by offloading processing to the client

It allows for immediate client-side validation without a round trip

It provides better security because the script logic is not exposed to the client
