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: "This language has a variety of statements but most would recognize the INSERT, SELECT, UPDATE and DELETE statements."

A block of code is set as follows:

SELECT parameter1, STTDEV(parameter2) 
FROM Table1 Group by parameter1 
HAVING parameter1 > MAX(parameter3)

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

$ sqlite3 testdatabase.db

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: " Then at the bottom of the page, within the Linked Frameworks and Libraries, click on the + and a modal window will appear."

Note
