With the customization features provided by Oracle Metadata Services (MDS), developers can customize the application using JDeveloper, making modifications to suit the needs of a particular group, such as a specific region or industry or site.

Using JDeveloper, you can implement customizations on existing artifacts that are provided. The application can also be extended with new custom artifacts that are packaged into a JAR file, and integrated using customizations on the existing application.

However customizations to the application require a lower level approach, for which JDeveloper needs to be used.
