Discussion Focus
How often have your students heard that “you have only one chance to make a good first impression?”
That’s why it’s so important to sell the importance of databases and the desirability of good database
design during the first class session.
Start by showing your students that they interact with databases on a daily basis. For example, how
many of them have bought anything using a credit card during the past day, week, month, or year? None
of those transactions would be possible without a database. How many have shipped a document or a
package via an overnight service or via certified or registered mail? How many have checked course
catalogs and class schedules online? And surely all of your students registered for your class? Did
anybody use a web search engine to look for – and find – information about almost anything? This point
is easy to make: Databases are important because we depend on their existence to perform countless
transactions and to provide information.
If you are teaching in a classroom equipped with computers, give some “live” performances. For
example, you can use the web to look up a few insurance quotes or compare car prices and models.
Incidentally, this is a good place to make the very important distinction between data and information. In
short, spend some time discussing the points made in Section 1.1, "Why Databases?" and Section 1.2
“Data vs. Information.”
After demonstrating that modern daily life is almost inconceivable without the ever-present databases,
discuss how important it is that the (database) transactions are made successfully, accurately, and
quickly. That part of the discussion points to the importance of database design, which is at the heart of
this book. If you want to have the keys to the information kingdom, you’ll want to know about database
design and implementation. And, of course, databases don’t manage themselves … and that point leads
to the importance of the database administration (DBA) function. There is a world of exciting database
employment opportunities out there.
After discussing why databases, database design, and database administration are important, you can
move through the remainder of the chapter to develop the necessary vocabulary and concepts. The
review questions help you do that … and the problems provide the chance to test the newfound
knowledge
