This list defines complexity levels for ADF applications. Once you have determined the complexity of your application, you can refer to the ADF Skills Chart to find the highest skill level recommended to have on the project in different areas.

Very simple

A very simple application uses a few simple standard components with default behavior to query and modify database data in tables. In order to be considered very simple, the application should have only few screens ( < 20). It must be acceptable that application functionality and visual appearance is dictated by ADF defaults.

Simple

A simple application uses standard UI components with simple declarative validation. Data is stored directly in database tables. A simple application can consist of many screens. It must be acceptable that application functionality and visual appearance is dictated by ADF defaults.

Normal

A normal application uses all standard UI components an mainly default functionality. Most validation is declarative. It will have only few or simple integrations with external systems. Data is stored directly in database tables. It must be acceptable that application functionality and visual appearance might be constrained by ADF standard components.

Complex

An application is considered complex if any of the following is true:

• The application uses PL/SQL APIs instead of tables
• The application uses data controls based on Web Services
• The application is integrated with external systems
• The application makes use of customization
• The application makes use of custom skins
• The application is large (200+ screens)

Very complex

An application is very complex if any of the following is true:

• The application uses custom components
• The application deviates significantly from normal behaviour
• The application is very large (500+ screens)
