What is an advantage of the Top Down approach to database design in Appian?

The Top Down approach to database design in Appian emphasizes the creation of conceptual models and high-level schemas before diving into the specifics of database tables and relationships. One of the key advantages of this method is that it allows for a more abstract view of data, which can be beneficial for understanding the overall structure and relationships without getting bogged down by the technical details.

When utilizing the Top Down approach in Appian, data architects can design conceptual models and then move directly to the creation of the database tables based on these models. This often means that modifying these tables does not require extensive coding knowledge, making it accessible for users who might not be as technically skilled. This accessibility is crucial in environments focused on rapid development and deployment, allowing teams to quickly adapt to changing requirements without the overhead of complex coding tasks.

This approach contrasts with methods that might require significant SQL development or coding for modifications. Such methods can introduce additional complexity and lead to longer development cycles, whereas the Top Down design streamlines the process of creating and managing database tables.
