Exercise 4: Developing the sample application 47
• Implement browsing and searching (“Lesson 8: Implementing Browsing and Searching”
on page 123).
• Enable database maintenance (“Lesson 9: Enabling Database Maintenance” on page 129).
• Restrict access to the Compass Travel application by requiring user authentication (“Lesson 10:
Restricting Access to ColdFusion Applications” on page 143).
How to proceed
Each lesson in the tutorial is designed to let you proceed at your own pace. At any time, you can
stop and later return to that place in a lesson so that you can complete all the sections in the
lesson.
Each lesson guides you through a scenario to enhance the Compass Travel Trip Maintenance
application. Sections within a lesson present basic programming concepts that you need to
understand before completing the section exercises.
Depending on your programming experience, you can read the entire lesson and then proceed to
the hands-on exercises, or you can skip some information in the lesson and proceed directly to the
exercises. For each exercise, there is a completed version of each file created or modified in that
lesson. The completed solution files are in the directory cf_root/cfdocs/getting_started/solutions.
Appended to each filename is the lesson and exercise number. For example, the version of the file
tripdetail.cfm that you would have after performing the steps in Lesson 5, Exercise 4 is named
tripdetail_lesson5_ex4.cfm. To use the solution file and continue with Lesson 5, Exercise 5, copy
the tripdetail_lesson5_ex4.cfm file to the cf_root/cfdocs/my_app directory, and overwrite the
tripdetail.cfm file if it already exists in the my_app directory.
