Conventions used
There are a number of text conventions used throughout this book.
Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "You can now start entering an alias for your input connection. Name it something such as airdelaystreaminginput."
A block of code is set as follows:
SELECT t1.Cartype, SUM(t2.mgNOx/60) as SumNOx FROM Cartraffic as t1 TIMESTAMPED BY ObservedT JOIN CarStats as t2 ON t1.Cartype = t2.Cartype GROUP BY t1.Cartype, TUMBLINGWINDOW(minute, 10)
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
SELECT CensusStation, COUNT(*) as Amount FROM Cartraffic TIMESTAMP BY ObservedT GROUP BY CensusStation, System.Timestamp()
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Please click Create to start the provisioning of your configuration."
