Data Catalog Applications¶

Data Catalog Applications are the applications that are automatically created when you create a data entity and publish it.
You can create Data entities through the Management > Data Catalog module.

When you publish a data entity, an Data Catalog application with the name “{DataEntityName}DataCatalogFlows” is created in the App Studio > Data Catalog Applications module.
This Data Catalog application has three process flows within with the following names.

• Add{DataEntityName}
• List{DataEntityName}
• Update{DataEntityName}

Locking/Unlocking Data Catalog Applications¶

The Locking or Unlocking feature for Data Catalog applications is the same as for applications. That is, you can lock or unlock a Data Catalog application and the lock/unlock applies to all the processes and entities within that application.

You need to unlock the Data Catalog application (created by different users) for editing or modifying details or for creating and editing any entities for that Data Catalog application.

When you create and publish a Data entity, a Data Catalog application is created with all the processes and entities within that Data Catalog application. The Data Catalog application thus created is locked automatically for other users. However, other users can view all the details of the application. If any other user wants to edit or modify the Data Catalog application, they need to unlock the Data Catalog application.

The locked Data Catalog application shows a lock symbol on the application card. When you open a locked Data Catalog application, the locked symbol appears on the title bar. If you try to edit or modify any locked Data Catalog application, it will show an error message as shown below.

For unlocking a Data Catalog application, follow the below steps.

1. Navigate to App Studio > Data Catalog Applications.

2. Click a Data Catalog application that is locked. The locked Data Catalog application will display a red lock symbol.

   
   

3. Click Open. The lock symbol is displayed on the title bar.

   
   

4. Click the Lock symbol on the title bar. The Data Catalog application gets unlocked and the lock symbol disappears.

Deleting Data Catalog Applications¶

You cannot delete a Data Catalog application or processes listed in the Data Catalog application. However, you can delete the Data Catalog data entity created in the Manage > Data Catalog section.

Process Flows in Data Catalog Applications¶

When you create a Data Catalog data entity and publish it through the Management > Data Catalog module, an Data Catalog application is created with the name “{DataEntityName}DataCatalogFlows” in the App Studio > Data Catalog Applications module.
