Conventions

In this book, you will find a number of text styles 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: "But for your reference, Excel looks for HTML <table> tags to identify tables on a website."

A block of code is set as follows:

SELECT *
FROM pmthistory a
JOIN users b on (a.userid = b.id)

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: "If we did not have the Clear All Filters button, the users would have to figure out how they would clear every slicer one at a time to start over."
