Release 10.1A: OpenEdge Reporting:
Query/Results Administration and Development

> ## Application databases

> To deploy all or a portion of an application database, you must perform a dump-and-load operation. These are the situations that force you to deploy all or a portion of an application database from the development environment to the user environment:

> - If the application database does not exist in the user environment, you must deploy the entire database.

> - The application database exists in the user environment, but there are some changes to the schema of the database that you must deploy to the user environment.

> - The application database exists in the user environment, but there is new data (for example, new user definitions in the `_User` file) that you must deploy to the user environment.

> A dump operation produces text files containing data definitions (`.df`) files and data (`.d`) files. Transfer these data definition and data files to the user environment to recreate the application database or to load updates into an existing application database. When you deploy a database, remember to deploy the source code for any trigger procedures associated with the application database.

> For more information about database triggers, see the OpenEdge Development: Progress 4GL Handbook . For more information about dumping and loading databases, see the OpenEdge Data Management: Database Administration .
