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.

Enabling data security

Role-based security is not enough to develop a completely secure application because the role-based security is applied at the client side and it's very easy for anyone to change the role name in the browser console and view the restricted UI. So, along with role-based security, data security is also important. Data security restricts what a user can fetch from the backend APIs.

If data security is applied with role-based security, and if someone spoofs the role from the browser console, then the REST call will return an empty dataset. Data security is applied on the server side so that it is always secure.

For the custom Business Objects created inside VB, security can be applied at the Business Object level, but field-level security is not possible. For external REST APIs, no additional security can be applied in the VB application. You have to rely on external API security to secure the data fetched from external REST calls.
