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: "The customer_service associates the customer and the service relations."

A block of code is set as follows:

<hibernate-mapping package="carportal" schema="carportal_app">
  <class name="Account" table="account">
    <id name="accountID" column="account_id">
      <generator class="identity"/>
    </id>

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

SELECT first_name, last_name, service_id
FROM customer AS c CROSS JOIN customer_service AS cs
WHERE c.customer_id=cs.customer_id AND c.customer_id = 3;

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: "Another option is to use a Linux emulator such as Cygwin and MobaXterm."
