3. Reference WPx/Tx.y/YY-MM-DD/PP Objectives of the research  Using the declarative models including Task, Domain and User models to generate the user interface and the application code.  Providing a methodology framework for developing a user interface to database application. This framework including:  A meta-model that governs the semantics of task, domain and user models.  A methodological process for UI generation.  A tool implemented based on this methodology  Implementing DB-USE tool to achieve the following purposes:  Easy to use  Generating the runable and complete code  Generate the UsiXML

6. Reference WPx/Tx.y/YY-MM-DD/PP DB-USE’s task model An Action task is a task used to describe the end-user command to the system such as close a dialog, delete a data record, search information, open a dialog and so on. An Operation task is a task used to describe the display of the information to the end-user or the reception of the information from the end-user.
