Test Bank For Database Systems Design Implementation and Management 12th Edition coronel Chapter 1 Database Systems 1 Chapter 1 Database Systems 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?

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
