What Made Oracle Forms Productive?

• Strong defaulting from DB

• Properties for artifacts

• Built-in Triggers

• Database aware features – LOV, Master Detail

• Simple UI Design – Defaulting + Components

• PL/SQL Coding?

• Simple Architecture

Productivity in Oracle ADF

How is it done?

ADF Business Components

A framework that simplifies developing Java EE business

services for developers familiar with 4GL tools,

declarative development, and relational databases

• Simplify data access

• Simplify validation and business logic

• Uses SQL based data views

• Separate data views from business logic

• Implement best practices

• Easy customization

ADF BC - Making Things Simpler

• Query by example any field

• Master/Detail coordination

• List of values

• Calculated fields

• Various validations

• Range fetching

• Web service interfaces

• Transaction control

• Locking mechanism

• State management

All done declaratively without coding!

Declarative Validation

Sometime ADF Results in Less Coding

• Examples:

• Get translation to code

– Usually coding in post-query or When-Validate-Item

– ADF no code needed (joined view)

• Master-detail synchronization over Forms

– Forms - Requires parameter passing

– Automatic in ADF

Even Simpler Than Java

• Groovy Script expressions

• Even simpler syntax than Java

if ( FirstName=="Lex" && newValue > 5000)

{

return false

} else

return true
