JDeveloper(OAF) Architecure

Model will take care the Data Base related Transactions, Model contains the following:

• Entity Object (EO)
• View Object (VO)
• Callable Statement (PL/SQL Statement)
• Prepare Statement (Single Select Statement)
• OADB Transactions (Oracle Apps Data Base Transactions)

View is nothing but the OAF Page Output. View is implemented by UIX (User Interface XML).

Controller will take care of web browser activities like HTTP Get and HTTP Post
Controller have got three methods:

• Process Request
• Process Forms Request (HTTP Get)
• Process Form Data (HTTP Post)

HTTP get: While loading the Page we use HTTP Get.
HTTP Post : After Loading the page if we want any changes the we use HTTP Post.
We will discuss in detail about MVC architecture in the next chapters.
The Below figure shows the interaction between Model, View, and Controller.
