Summary
As described in this lesson, ColdFusion offers several alternatives to validating data. If
you are familiar with standard page validation code, ColdFusion supports these
development approaches. However, ColdFusion form tags simplify data validation.
Additionally, you can use JavaScript with ColdFusion to execute client-side functions.
In the next lesson
Now that you are sure that your application can save valid data, in the next lesson, you
will write code to add trips to the database. Additionally, you will add logic to update
existing trip data in the Trips table.
