Overview of this book

Organizations are moving their applications, data, and processes to the cloud to reduce application costs, effort, and maintenance. However, adopting new technology poses challenges for developers, solutions architects, and designers due to a lack of knowledge and appropriate practical training resources. This book helps you get to grips with Oracle Visual Builder (VB) and enables you to quickly develop web and mobile applications and deploy them to production without hassle. This book will provide you with a solid understanding of VB so that you can adopt it at a faster pace and start building applications right away. After working with real-time examples to learn about VB, you'll discover how to design, develop, and deploy web and mobile applications quickly. You'll cover all the VB components in-depth, including web and mobile application development, business objects, and service connections. In order to use all these components, you'll also explore best practices, security, and recommendations, which are well explained within the chapters. Finally, this book will help you gain the knowledge you need to enhance the performance of an application before deploying it to production. By the end of this book, you will be able to work independently and deploy your VB applications efficiently and with confidence.

Loading data on page load

In the previous section, we learned about the different life cycle events of a page; now we will execute a vbEnter event, which will help to load page data before a page is loaded.

In this section, we will execute a use case that will load data from the Employee Business Object before page load and show the data in a table component. The following are the high-level steps to achieve the use case:

  1. Create a type and a variable of the Array Data Provider (ADP) type.
  2. Register the vbEnter event and load the Employee Business Object data.
  3. Populate the Employee Business Object data from the ADP variable in a table.

We'll create a new web application with the name chapter7 under our VBCSBook application and develop all the use cases in this web application. Refer to Chapter 3, Exploring Visual Builder Ingredients, specifically the Understanding the application's structure section, to see how to create a new web application.
