What would trigger a Database Exception?

• A. Invalid data type in user input
• B. System overload
• C. Incorrect handling of invalid credentials
• D. Database connectivity issues

Answer: (D)

A Database Exception is primarily related to issues that arise during interactions with the database. One significant reason this type of exception is triggered is due to connectivity issues. When an application attempts to communicate with a database and fails to establish a connection—whether due to network issues, the database server being down, or misconfigurations—this results in a Database Exception. Connectivity problems can prevent the application from querying or updating records, leading to errors that must be managed programmatically. Such exceptions are critical to handle, as they can disrupt the user's experience and affect the application’s overall performance. Other potential issues, such as invalid data types from user input or handling invalid credentials, typically fall under validation or authentication exceptions rather than a direct database exception. System overload may lead to performance issues but does not specifically indicate a failure in database operations related to connectivity.
