The reader should know the basics of programming, as well as the basics of SQL and operations on databases. Basic knowledge of business processes will also be helpful. This book also deals with the subject of UI5; therefore, it is worth the reader knowing the basics of JavaScript. 

To create code in ABAP, the readers also need access to SAP systems with the developer key. 

To create applications in UI5, the readers should create a trial account in the SAP Cloud Platform. The SAP Web IDE Full-Stack developer environment is available there. The programming environment allows you to create and extend SAP applications on a full stack for browsers and mobile devices.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "In the Details window, create lines %C1 and %C2 with the values that are shown in the following screenshot."

A block of code is set as follows:

<script
    id="sap-ui-bootstrap"
    src="resources/sap-ui-core.js"
    data-sap-ui-libs="sap.m"
    data-sap-ui-theme="sap_belize">
</script>

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

data-sap-ui-bindingSyntaxt="complex"
data-sap-ui-resourceroots='{ "my.namespace":"./" }'

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

$ mkdir css
$ cd css

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: "Select System info from the Administration panel."
