# App Designer

**App Designer** is a **Smart Form and Data Modeling tool** in ONEWEB that allows users to define and manage **Entities**, which form the foundation of application data and user interfaces.

In the ONEWEB platform, an **Entity** represents a collection of related business attributes that together describe a real‑world business object.\
Examples of entities include:

* Customer
* Order
* Product
* Tax Invoice

Each entity serves as a **single logical unit** that can be used across the platform, including:

* Smart Forms
* Process workflows
* Data validation and storage
* User interaction screens

***

### Purpose of App Designer

App Designer is designed to help users:

* Define business data structures in a centralized manner
* Model entities that represent real‑world business concepts
* Create reusable data components for forms and processes
* Ensure consistent data usage across applications
* Bridge the gap between data design and UI configuration

By using App Designer, applications can maintain **data consistency, reusability, and scalability**.

### Entity Concept in ONEWEB

An **Entity** in ONEWEB:

* Groups related business attributes into one object
* Acts as the primary data model for Smart Forms
* Can be reused across multiple forms and processes
* Represents a business concept rather than a technical table

In most business scenarios, an Entity in ONEWEB can be directly mapped to:

* Use case diagrams
* ER diagrams
* Business domain models

This alignment allows both business and technical users to work with a **shared understanding of data structures**.

{% hint style="warning" %} **Important**\
The first step in creating any **Smart Form** on the ONEWEB platform is to **define an Entity**.

It is critical to carefully analyze and define the **scope and responsibility** of the business entity before starting form configuration.\
A well‑designed entity leads to:

* Cleaner form designs
* Simpler process integration
* Easier maintenance and future enhancements {% endhint %}

***

### Role within ONEWEB Platform

App Designer works closely with other ONEWEB designers:

* **Page Designer** – Uses Entities as data sources for UI components
* **Process Designer** – Uses Entities to pass and manage data within workflows
* **Microflow Designer** – Uses Entities for logic and integration

Together, these tools ensure a seamless flow from **data definition → user interaction → process execution**.

***

### Summary

**App Designer** is the foundation for data modeling and Smart Form design in ONEWEB.

Key points:

* Defines Entities that represent business objects
* Entities group related business attributes
* Entities are reusable across forms, processes, and logic
* Proper entity design is essential for scalable applications
* App Designer ensures consistency across the entire ONEWEB platform

This reference section provides the conceptual basis for understanding how data is modeled and used throughout ONEWEB applications using **App Designer**.
