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, user input, and Twitter handles are shown as follows: "We are using HR as our user for making the connection."

A block of code is set as follows:

STEVE 1000 2000 3000 4000
JAMES 2000 2500 3000 3500
ANDY 4000 4000 4000 4000

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

IIF( ISNULL (JOB_ID), NEXTVAL, JOB_ID)

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 open the PowerCenter Designer screen, navigate to Start | All Programs | Informatica 9.5.1 | Client | Power Center Client | Designer."
