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.

A block of code is set as follows:

[
  { $match: {"customer.name" : "Baane Mini Imports"} },
  { $group: {"_id" : {"orderNumber": "$orderNumber", "orderDate" : "$orderDate"}, "totalSpend": { $sum: "$totalPrice"} } }

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

db.Orders.find({"priceEach":{$gte:100},"customer.name":"Baane Mini Imports"}).count()]

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: "Set the Step Name property to Select Customers."
