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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, and user input are shown as follows: "We'll create a calculated field named Floor to determine whether an apartment is upstairs or downstairs."

A block of code is set as follows:

IF [Apartment] >= 1 AND [Apartment] <= 3 
 THEN "Downstairs" 
ELSEIF [Apartment] > 3 AND [Apartment] <= 6
 THEN "Upstairs" 
ELSE "Unknown"
END

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Drag and drop the Customer field onto the Rows shelf."
