MDS-Meta Data Service

OAF Runs using MDS logic:


Meta is the object in a web page,Data being access n a request on Meta,and services is the connection from database and action performed.


OAF session is opened using Jdeveloper.


The JDeveloper OA Extension offers the following design time tools:
·         Unified Modeling Language (UML) tools to model and generate business logic
·         Guided user interface to lay out client user interfaces
·         Code generation for Controller classes.

The OA Framework View is implemented using an Oracle technology called UIX. UIX stands for User Interface XML; it uses XML to describe the components and hierarchy that make up an application page. UIX also provides the runtime capabilities to translate that metadata into HTML output that can be shown on a web browser or a mobile device. The metadata used to describe the UI is loaded into a database repository called Metadata Services (MDS), which is used at runtime to generate the HTML pages
