3. What is personalization in OAF?

Oracle Apps Framework has an OA Personalization Framework associated with it so that you can personalize any OAF page in an Oracle E-business Suite application without changing the basic or underlying code of that OA Framework page. Oracle Application Framework makes it very easy to personalize the appearance of the page or even the personalization of data displayed on an OA Framework page.

    1. Function Level

    2. Localization Level
    3. Site Level
    4. Organization Level
    5. Responsibility Level
    6. Admin-Seeded User Level
    7. Portlet Level
    8. User Level

5. what is a Javabean?
JavaBeans is an object-oriented programming interface that lets you build re-useable applications or program building blocks called components that can be deployed in a network on any major operating system platform.

6. What is query Bean?
QueryBean is used to execute and return the results of a query on behalf of the QueryPortlet application.

7. What is the difference between auto-customization search criteria and result based search?
Results based search generates search items automatically based on the columns on the results table.
In Autocustomization search we need to set what all fields are required to display as a search criteria.

8. What is MDS?
MDS is MetaData Service. When a web page is broken into small units like buttons,fields etc they are stored in a database. These are not stored as binary files but as data in tables. The data are present in JDR tables. MDS provides service to store & return page definitions. MDS collects those definitions in components/fields in a meaningful manner to build a page.

9. What is XML?
XML is a markup language for documents containing structured information.
Structured information contains both content (words, pictures, etc.) and some indication of what role that content plays (for example, content in a section heading has a different meaning from content in a footnote, which means something different than content in a figure caption or content in a database table, etc.).

10. What is the difference between customization and extension?
Customization is under direct user control. The user explicitly selects between certain options. Using customization a user can:

  1. Create a new custom Application
  2. Alter the functionality of an application
  3. Alter existing UI
  4. Alter existing business logic
Extension is about extending the functionality of an application beyond personalization. Using extension we can:
  1. Add new functional flows
  2. Extend or override existing business logic
  3. Create New application/module
  4. Create New pages and regions
  5. Create New attributes
  6. Extend/Override defaults & validations
