	Table of Contents

	Introduction

For the most part, we have tried to keep conventions in this book as simple as possible.

Many new terms are identified and are printed in italics.

In the listings, all code that you type in (Input) appears in boldface monospace . Output appears in standard monospace.

SQL code and keywords have been placed in uppercase for your convenience and general consistency. For example:

  SELECT * FROM PRODUCTS_TBL;  PROD_ID    PROD_DESC                       COST ---------- ------------------------------------ 11235      WITCHES COSTUME                29.99 222        PLASTIC PUMPKIN 18 INCH         7.75 13         FALSE PARAFFIN TEETH            1.1 90         LIGHTED LANTERNS               14.5 15         ASSORTED COSTUMES              10 9          CANDY CORN                      1.35 6          PUMPKIN CANDY                   1.45 87         PLASTIC SPIDERS                 1.05 119        ASSORTED MASKS                  4.95 9 rows selected.

The following special design features enhance the text:
