Knowing the technologies used in VB
You don't require any programming skills to work with on VB as it provides a drag and drop feature with which you can build an enterprise-grade application. But it's really worth knowing what technologies are used in VB development:
- JET: JET stands for Java Extension Toolkit, which is Oracle open source technology that is used to build interactive UIs. VB uses JET to design UIs using a rich set of UI components for web and mobile applications. To find out more about JET, you can visit http://oraclejet.org. You can also refer to the JET cookbook for working with UI components at https://www.oracle.com/webfolder/technetwork/jet/jetCookbook.html.
The following screenshot shows various JET components in the VB component palette:

- HTML5: HTML stands for Hypertext Markup Language, which is used to build responsive web user interfaces. In combination with JET, VB allows us to use HTML5 to extend your UI's functionality in order to make interactive web and mobile applications. To learn more about HTML5, refer to https://www.w3schools.com/html/.
- JavaScript: JavaScript is a web scripting language that's used to develop and control dynamic content. It is also used for client-side validation of web pages. In VB, JavaScript can be used extensively to extend web page functionalities such as client-side validation, filtering records at the client side, and so on. To learn more about JavaScript, refer to https://www.javascript.com/.
- CSS: CSS stands for Cascading Style Sheets, and is used in web applications to make UIs interactive. With the help of CSS, you can completely change the design of web applications. VB also allows you to write custom CSS to make your web and mobile application interactive. To learn more about CSS, refer to https://www.javatpoint.com/css-tutorial.
Having understood what technologies you should know for VB, next we'll explain the VB architecture.
