Conventions

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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The json.load() function loads the data into Python."

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

$ pig ./BigData/pig_sentiment.pig

New terms and important words are shown in bold.
