Course description

Overview: This course is designed for the non-programmer. Individuals with programming or scripting

experience probably will not need to cover some of the information in this book to get started with

ColdFusion development. Students taking this course should be experienced with HTML, Internet

concepts, SQL fundamentals, and database fundamentals. This course introduces students to the syntax,

functions, tags, and possible development solutions they're likely to encounter as they begin to develop

ColdFusion applications.

Prerequisites: This course is designed for the experienced computer user who has an understanding of

Internet functionality and fairly extensive experience with HTML. The target student should also

understand database and SQL basics. We strongly recommend that all students considering this course

should first take

 

ColdFusion: Creating Database-driven Web Sites, Level 1. Many vital concepts are

omitted from this book because they were covered in Level 1 of this course series. A student who is not

experienced with HTML, SQL basics, database fundamentals, and ColdFusion fundamentals, should take

the following Element K courses before proceeding with this course:

 

HTML 4.0 Level 1

 

HTML 4.0 Level 2

 

SQL Fundamentals

 

Introduction to MS Access 97

 

ColdFusion: Creating Database-driven Web Sites, Level 1

Delivery method: Instructor-led, group-paced, classroom-delivery learning model with structured handson

activities.

Benefits: Students will learn how to create dynamic Web sites that interact with databases and user

input.

What's next: ColdFusion: Creating Database-driven Web Sites, Level 2 is the second course in this

series. Students who want to continue to after this course can take ColdFusion: Creating Databasedriven

Web Sites, Level 3.

IMPORTANT

Students, training centers, etc do not need to purchase the full, enterprise or professional edition of

ColdFusion to use this book. We’ve developed the course using HomeSite, Microsoft’s Personal Web

Server, and ColdFusion Express, a freely available version of ColdFusion. Each of these applications can

be found for free on the Web, although it’s suggested that anyone using this book purchase HomeSite

from Allaire. This setup was chosen because it opens up the course to anyone who wants to learn

ColdFusion, regardless of their ability to purchase the $3000 version ColdFusion.

ColdFusion: Creating Database-driven Web Sites, Level 2

Performance-based objectives

Lesson objectives help students become comfortable with the course, and also provide a means to

evaluate learning. The concepts and tasks in this book are designed to provide the student with the skills

necessary to create a variety of applications, in addition to the specific applications they'll create. Upon

successful completion of this course, students will be able to:

 

Create dynamic tables to output query results, apply date functions to create a date stamp, and

implement a drill-down application.

 

Create an application that updates existing database records and records the date and time of

modifications.

 

Create an application that inserts new records and another that deletes existing records.

 

Enable form field validation with a variety of methods, and re-populate a form with submitted

data.

 

Create a keyword search application that can handle a variety of user criteria.

Additional information: ColdFusion Express

ColdFusion Express doesn't support all of the tags available with the full versions of ColdFusion server,

the Professional and Enterprise editions. The most fundamental tags are supported, but as you continue

to learn ColdFusion development, you should consult the CFML documentation that comes with all

ColdFusion products. This documentation will provide you with more information on all the ColdFusion

tags at your disposal. You can access this documentation via ColdFusion Administrator. Also, there are

over 200 functions available in ColdFusion 4.0. Of course, we can't cover them all - this course presents

certain ColdFusion functions that are best suited for the given task. Your own development efforts are

likely to require the use of other ColdFusion functions.

ColdFusion 4.0 Express is a freely available, pared-down version of ColdFusion. Because of its

availability to anyone interested in learning ColdFusion, and the fact that it supports many of the most

fundamental ColdFusion tags, this course was developed with ColdFusion 4.0 Express. Anything

developed for ColdFusion Express will work fine on the full versions of ColdFusion Server.
