Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "If you're using a Mac, Navicat should simply be in your Applications folder unless you dragged and dropped it elsewhere from the installer window."

A block of code is set as follows:

BEGIN
    INSERT INTO emp_log SET emp_id = NEW.id, date_created = NOW();
END

Any command-line input or output is written as follows:

CREATE TABLE if not exists emp_log (
   id int auto_increment primary key,
   emp_id int,
   date_created datetime
  );

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "To launch Navicat in Windows 7 and earlier, go to Start menu | All Programs | PremiumSoft and click on the version of Navicat you have installed on your PC."
