Ans: Oracle Application Framework is a development framework used to build and customize applications within the Oracle E-Business Suite.
Ans: OAF follows a Model-View-Controller (MVC) architecture, where the Model represents the data, the View represents the user interface, and the Controller handles the interaction between the Model and View.
Ans: The key components of OAF include Pages, Regions, Controllers, and Entities.
Ans: OAF uses the Business Components for Java (BC4J) framework for data binding, which allows seamless integration between the user interface and the underlying data model.
Ans: A Page in OAF represents a single user interface screen and consists of multiple regions.
Ans: Controllers in OAF handle the flow of control between the Model and View components, including event handling and navigation.
Ans: The different types of Controllers in OAF include Page Controller, Region Controller, and Task Flow Controller.
Ans: A Task Flow in OAF represents a sequence of pages and defines the navigation and data flow between them.
Ans: OAF provides personalization features like Profile Options, User Preferences, and Personalization Framework to customize the user experience.
Ans: Entities in OAF represent the business objects and handle data manipulation and validation.
Ans: View Objects represent query definitions used to retrieve data, while Entity Objects handle data manipulation and validation.
Ans: Exceptions in OAF are handled using the OAF Exception Handling framework, which allows custom exception handling and error messaging.
Ans: Key features of OAF include data binding, customization capabilities, personalization options, integrated security, and support for multi-language and multi-currency environments.
Ans: OAF provides built-in features and libraries for handling multi-language and multi-currency requirements, allowing applications to be customized for different regions and languages.
Ans: View Objects in OAF represent query definitions used to retrieve data from the database and provide data to the user interface components.
Ans: OAF supports integrated security features, including user authentication, role-based access control, and data security.
Ans: BC4J is the predecessor of ADF Business Components and provides similar functionality for data binding and business logic.
Ans: OAF provides debugging options such as logging, tracing, and diagnostic tools to identify and resolve issues in the application.
Ans: The customization process in OAF involves extending or modifying existing components, adding new components, and configuring properties to meet specific requirements.
Ans: OAF provides built-in mechanisms to handle concurrent user access, including optimistic locking and row-level locking.
Ans: Personalization in OAF refers to the ability to customize the user interface, layouts, and functionalities based on user preferences and roles.
Ans: OAF allows developers to extend standard E-Business Suite functionality by creating custom pages, regions, and components that integrate seamlessly with the existing application.
Ans: OAF provides validation features through the use of validation rules, declarative validation, and custom validation methods.
Ans: Performance optimization in OAF involves techniques such as query tuning, caching, minimizing network round trips, and efficient use of data binding.
Ans: OAF provides features for handling internationalization, such as resource bundles for language-specific labels, date and number formatting, and currency conversion.
