Introduction CODE GENERATION is code that writes code [1] . Automatic Code Generation can Maintain consistent code quality and allows your code to evolve quickly in response to metadata changes Extend reuse to include code with similar patterns Result: increased speed, reusability, agility, and consistency in your application development

CODE GENERATION is code that writes code [1] .

Automatic Code Generation can

Maintain consistent code quality and allows your code to evolve quickly in response to metadata changes

Extend reuse to include code with similar patterns

Result: increased speed, reusability, agility, and consistency in your application development
