Building Enterprise Apps with Oracle Visual Builder

# Building Enterprise Apps with Oracle Visual Builder

Oracle Visual Builder is a powerful low-code platform designed for building enterprise-grade web applications quickly, without sacrificing customization or scalability. In this guide, we'll explore how to leverage Visual Builder to create modern business apps, connect to APIs, and implement advanced features using custom JavaScript and REST integrations.

## Why Oracle Visual Builder?

Visual Builder stands out in enterprise environments thanks to:

- **Low-Code + Pro-Code Flexibility**: Drag-and-drop components with support for custom JavaScript logic - **Seamless Oracle Integration**: Native support for Oracle SaaS, ERP, and REST services - **Security & Authentication**: Enterprise-ready identity and role-based access control - **Faster Delivery**: Ideal for delivering internal tools and business portals rapidly

Whether you're modernizing legacy systems or creating dashboards from scratch, Visual Builder helps you ship production-ready apps faster.

## Getting Started

To begin, you'll need access to Oracle Cloud and Visual Builder Studio:

```bash 1. Log in to Oracle Cloud Console 2. Navigate to Developer Services → Visual Builder 3. Create a new Web Application project ```

Once inside the project workspace, you can design pages using the built-in Page Designer and bind data directly from REST endpoints.

## Working with REST Data

Most enterprise apps rely on dynamic data. Visual Builder makes it easy to connect external APIs:

``` Service Connections → + Create → Add REST Endpoint ```

You can then drag data onto pages, auto-generate tables, and use Action Chains for CRUD logic — no manual wiring needed.

## Adding Custom Logic (Pro-Code Mode)

While Visual Builder is low-code first, you can go further with custom JavaScript:

```javascript // Example: Custom validation in Visual Builder PageModule.prototype.validateInput = function(value) { if (!value) { throw new Error("Field cannot be empty"); } return true; } ```

Custom code allows you to implement complex business rules, validations, and conditional UI behavior.

## Best Practices

- **Use Action Chains for reusable logic** - **Keep API services centralized in Resource Catalog** - **Combine low-code UI with modular JS functions** - **Test using Oracle Visual Builder Tester for QA**

## Deploying to Production

Deployment is streamlined within Oracle Cloud:

``` Deploy → Stage Application → Publish to Live URL ```

You can host apps internally or expose them as standalone portals to external users.

## Conclusion

Oracle Visual Builder empowers development teams to deliver enterprise apps faster while still allowing customization through code. With its integration-ready architecture and low learning curve, it's a top choice for Oracle ecosystems.

Whether you're automating workflows, building dashboards, or creating customer portals — Visual Builder offers the flexibility to scale from prototype to production.
