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 are shown as follows: "Because there are no keys to link tables together, the ADO.NET Data Services methods that deal with links are unavailable to use, including AddLink, DetachLink, and SetLink".

A block of code will be set as follows:

CREATE TABLE [dbo].[Customers](
[CustomerID] [int] IDENTITY(1,1) NOT NULL,
[CustomerName] [varchar](50) NOT NULL,
[CustomerAddress1] [varchar](50) NOT NULL

When we wish to draw your attention to a particular part of a code block, the relevant lines or items will be shown in bold:

Imports System.ServiceModel
 ' NOTE: If you change the class name "IERPService" here, you must also update the reference to "IERPService" in Web.config.
<ServiceContract()> _
Public Interface IERPService

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 our text like this: "The first setting we need to change is, setting the Script for database engine type option to the SQL Azure Database option, as seen in the following screenshot".
