What is a disadvantage of the Top Down approach in Appian Data Design regarding editing?

The Top Down approach in Appian Data Design involves defining the data model through higher-level concepts like entities and relationships before specifying the underlying details like data types and constraints. One of the disadvantages of this approach is that it often necessitates direct editing of XSD (XML Schema Definitions) files to implement advanced database features.

Advanced DB features, such as complex data types or specific constraints, may not be easily represented in the higher-level abstract model initially defined. As a result, developers may have to delve into the XSD to adjust the schema according to these advanced requirements. This process can be cumbersome and adds complexity, as it deviates from the more intuitive, visual design approach that may be expected when using the Top Down method.

In contrast, other choices do not capture this particular disadvantage. While direct editing of XML schemas may apply in certain contexts, the core issue with advanced database features specifically relates to the necessity of modifying XSD files. The requirement for strict naming conventions, while a potential consideration in database design, does not directly pertain to the disadvantages of using the Top Down approach.
