How does the `<cfcatch>` tag contribute to application robustness in ColdFusion?

The `<cfcatch>` tag in ColdFusion is a crucial component for building robust applications by providing error handling capabilities. Robustness, in this context, refers to an application's ability to gracefully handle unexpected situations, such as errors in code execution, database connection failures, or invalid user input, without crashing or displaying confusing messages to the user. The `<cfcatch>` tag is part of a broader error handling structure that includes `<cftry>` and `<cfthrow>`. First, the `<cfthrow>` tag is used to explicitly raise an error. This is useful when you detect a condition that should halt normal processing and signal an error state. For example, if a database query returns no results when it's expected to, you might use `<cfthrow type="Application" message="No data found." />`. The `type` attribute categorizes the error (Application, Database, Custom, etc.), and the `message` provides a descriptive expla....
