# Master Data Import / Export

The **Master Data Import / Export** utility in **App Designer** allows users to **export and import master database setup data** between environments.\
This utility is primarily used to migrate or synchronize **system‑level configuration data** such as metadata, constants, menu definitions, and internal setup tables.

It plays a critical role in ensuring **consistency across environments** such as Development, Test, and Production.

***

### Purpose of Master Data Import / Export

The Master Data Import / Export utility is designed to:

* Migrate master setup data between environments
* Synchronize internal system configurations
* Support environment initialization and setup
* Reduce manual configuration effort
* Preserve consistency of system metadata

This utility focuses on **platform configuration**, not business entity data.

### Master Database Setup Overview

Master database setup tables contain **core platform configuration data** required for ONEWEB to function correctly.\
These tables store metadata and internal settings used across applications.

The master setup tables available for import/export include:

* `m_metab_constant`
* `m_metab_system`
* `m_metab_button_process_action`
* `m_metab_button_master`
* `m_locales`
* `m_process_menu`

Each table represents a specific aspect of system‑level configuration.

***

### Exporting Master Data

The **Export** tab in the Master Configuration window lists all master setup tables that can be exported.

#### Export Process

* Select one or more master setup tables
* Click the export action
* Each selected table is exported as a **JSON file**
* The exported files are downloaded to the local machine

Exported JSON files can later be imported into another environment.

***

### Importing Master Data

The **Import** tab allows users to import master setup data from JSON files.

#### Import Process

Users can import master data by:

* Clicking **Browse** and selecting the JSON files, or
* **Dragging and dropping** JSON files into the highlighted import area

Once imported, the selected master configuration data is applied to the current environment.

***

### Important Considerations

* Master Import / Export affects **system‑level configuration**
* Incorrect import may impact application behavior platform‑wide
* Always ensure environment compatibility before importing
* Avoid overwriting master data unintentionally in production environments

***

### Usage Guidelines

* Use Master Import / Export during environment setup or migration
* Export master data before making significant configuration changes
* Import master data in the correct order when required
* Restrict access to this utility to experienced administrators
* Validate system behavior after import

***

### Summary

The **Master Data Import / Export** utility provides a controlled way to migrate and manage **internal ONEWEB configuration data**.

Key points:

* Used for system‑level configuration, not business data
* Exports and imports master setup tables as JSON
* Supports environment synchronization
* Essential for platform initialization and governance

Used properly, Master Data Import / Export ensures **stability, consistency, and reliability** across ONEWEB environments.
