Salesforce Platform Developer Practice Exam

Which best describes a Metadata-driven development model?

1. Requires extensive coding for each app

2. Apps defined as declarative "blueprints"

3. Utilizes hardware for app development

4. Focuses solely on visual design

The correct answer is: Apps defined as declarative "blueprints"

A metadata-driven development model emphasizes the use of metadata to define and configure applications. In this model, applications are created by specifying declarative "blueprints" which can outline the behavior, logic, and structure of the app, rather than relying on extensive coding for each component. This approach allows developers to build applications more quickly and efficiently, as changes can often be made by altering the metadata rather than rewriting code. By using metadata as the primary means of defining applications, developers can leverage built-in functionalities of the platform, which enhances scalability and maintainability. This results in applications that can be easily adapted to changing requirements without the need for extensive programming, which is a key advantage in agile development environments. While other choices may touch on aspects of app development, they do not align with the core principle of the metadata-driven model, where the focus is on declarative design rather than manual coding, hardware considerations, or purely visual elements. The strength of this model lies in its ability to abstract complexity and facilitate rapid development cycles by using metadata to drive application behavior.
