Do I take a Top-Down or Bottom-up approach to Data Modeling?

This frequent question Donna Burbank gets from clients.  This is my understanding. A top-down approach is conceptual. It looks at the big picture and fits in the details. In a bottom-up approach, a data modeler uses the technical details (tables, rows, columns, stored procedures, macros, etc) to create the data model.  From what I learned, a hybrid approach is usually used by clients and it depends on the use case or purpose and audience. If it is more of a business audience and less technical, then a more top-down model may be easier to understand.
