Service-Now prerequisites
To start with Service-Now, you should have a basic understanding of Java scripting and SQL. Please keep in mind that as an admin or developer you are not allowed to access the database layer or application code layer but Service-Now provides its own classes, functions, and methods for development and other work. In addition, if we talk about the supporting technology behind this application, then Service-Now is Java-based and uses Oracle, MySQL, and SQL server databases and as a web server, Tomcat is being used.
